Command and Staff Training Simulation - I/ITSEC 2014 Demo

Whether you’re wargaming or managing a local crisis, simulation plays an important role in command staff training. Its job is to model the situation to provide learning opportunities for the trainees and to stimulate the command and control (C2), or Mission Command systems, they use. Simulation helps trainees and instructors plan the battle, fight the battle, and review the battle.

Brian Spaulding spent his days at I/ITSEC 2014 showing our visitors how MÄK tools are specialized for Command Staff Training. He explains how our most recent version of VR-Forces highlights aggregate-level simulation (with a new "thunder run" demonstration) and how our WebLVC-based web app helps decision-makers accomplish specific training objectives in a light-weight, interoperable way. Check out our demos with Brian below.

Here’s more about our Command Staff Training approach.

A solid foundation to a bigger, better world

Whole-Earth simulation
I spent a few minutes pulling threads about whole Earth simulation out of Jim Kogler's mind. Here's what I learned: There seems to be a general misunderstanding these days about the ability of game engines and military simulation systems to accurately represent the whole planet Earth in training simulations. Jim, why are people interested in modeli...

Introducing MAK Legion: a next-generation scalability and communication framework delivering millions of entities

Introducing MAK Legion: a next-generation scalability and communication framework delivering millions of entities

I'm excited to introduce the latest innovative technology our team has been developing: MAK Legion  a next-generation scalability and communication framework that can manage and deliver millions of entities in both local and cloud deployment environments.

As you know, MAK has been a trusted and leading provider of simulation interoperability products since our inception 30 years ago. But about two years ago, we asked ourselves an important question, inspired by the needs of the US Army Synthetic Training Environment program: "If we had the chance to re-design DIS or HLA today to meet tomorrow's most aggressive scalability requirements, and to better leverage modern technology such as multi-core machines, high-bandwidth networks, massively-multiplayer gaming paradigms, and cloud services  what would it look like?" Legion represents the answer to that question.

Legion's modern data-oriented implementation, client-server approach to mirroring of state, whole-earth geographic interest management, thread-safe API, simplified ownership transfer, reuse of SISO Enumerations and DIS/RPR data types, and powerful code-generation tools all contribute to Legion's ability to make large numbers of entities easy to manage from any engine or application.

Going Hybrid in 2021

2020 transformed us. The way we did business came to a halt, and we were all forced to navigate a world under lockdown – we experienced an immediate shift to all things virtual, and there was a steep learning curve. (See below for a roundup of our articles that outline our approach to make virtual events and meetings more engaging, more personal, and more human.) 

This year, we’re taking advantage of our lessons learned to bring you a richer, better MAK experience. We’ve heard from many customers and friends that they’re ready to re-engage personally with us - we are excited for this, though we understand that the definition of  “personal” will be unique to every company. As we expect to see the world start to emerge from complete lockdowns, we are modulating our approach to meetings so that we can connect more deeply and personally with you where you are, both physically and virtually, through a hybrid seminar session approach.

Here’s how it works...

Changing the world by making virtual events better

We’re all entering into the 8th month of our new pandemic-reality. It’s tedious, it’s different, it’s changed how everyone does business — and who knows when the world will get back to normal. Dan Brockway, MAK’s VP of Marketing and my colleague, recently wrote a LinkedIn article about how, since the pandemic started, our shift to all-virtual everything has created a sense of “virtual event fatigue”. I get it, and I feel it, and... well, I agree with Dan that we can do better. But what does doing better *actually* look like?

Getting ahead of the game with 3D modeling and simulation

Getting ahead of the game with 3D modeling and simulation

This article was originally written and posted for publication in ST Engineering’s Agil Blog

At the dawn of the new millennium, two of the biggest aircraft manufacturers were vying for a $200 billion contract to build America’s next-generation fighter jet – the F-35 Joint Strike Fighter.

The Air Force demanded a fighter jet that would be faster and more maneuverable, while the Navy needed a version with longer wings to land on its aircraft carriers. But among the biggest challenges was to build a third variation which would be a world-first – one that could land vertically on shortened runways for the Marine Corps.

Head in the Clouds: Learnings from deploying MAK ONE in the cloud

Modeling, Simulation & Training systems have been interoperating in local and wide area networks long before there even was an ‘Internet’ - it's safe to say that we’re no strangers to complex information technology (IT) architectures. That said, the commercial world of IT has exploded over the years. We've already taken a deep dive into the pulse of modern IT in our MAK ONE Guide to Virtualization, and we've illustrated how MAK products are designed to play to the advantages of servers, virtualization, and public/private clouds. Today I'd like to share a few learnings from our cloud deployments on AWS (Amazon Web Services) and our private cloud to demonstrate the world of opportunities available with MAK ONE. Our heads are already in the cloud - join us!

Using Scenario Events to Trigger Simulation Action

When VR-Forces added ‘scenario events’ back in release 4.3, the intent was to support a Master Scenario Events List (MSEL). In operations-based or discussion-based exercises, a MSEL provides a timeline and location for expected exercise events and injects -- actions that push the scenario forward.

Using Qt Designer to Create Dialog Boxes for Lua Scripts

One of the features of VR-Forces Lua scripting that makes it so easy to create useful tasks and sets is automatic generation of dialog boxes. This feature makes it so easy to create dialog boxes that our developers often use it to create the dialog boxes for new C++ tasks, instead of using the Qt API. (VT MAK uses Qt, a cross-platform API to create the graphical user interfaces (GUIs) for its products.) Unfortunately, other than providing some support for indenting, the automatically generated dialog boxes are very generic in their layout. Prior to VR-Forces 4.6, if you wanted a dialog box that supported the user with a UI design that was more than utilitarian, you were out of luck. However, in VR-Forces 4.6 we added the ability to use Qt Designer to create custom dialog boxes for Lua scripted tasks and sets.

Tech Tip: Which Compiler Do I Need? Making Sense of Microsoft Compiler Versions

The Windows versions of MAK products are built using the Microsoft Visual C++ (MSVC++) compiler. Because application and library compatibility is usually broken between different versions of the compiler, applications that interoperate must be built using compatible compilers. To help customers choose the correct version of an application to install, each MAK application installer includes the compiler version it was built with in the installer filename. Additionally, the About box for each application includes the compiler used to build it.

VR-Forces 4.6 - Order of Battle

When you are creating a scenario in VR-Forces, you usually have complete access to all of the simulation objects in a simulation model set (SMS) and can create as many as you want. However, in the real world, commanders do not have unlimited resources. They are constrained by their Order of Battle (OOB), which specifies the men and material available in a hierarchical structure. VR-Forces now supports the creation of OOBs. You create an Order of Battle in the context of a scenario. However, once you create an OOB, you can export it and then import it into other scenarios. This lets you quickly create new scenarios that use the same OOB for training or scenario development.

Strategies for Building VR-Forces Scenarios

Many of the web sites that most of us read regularly are not composed of static pages. They pull content from a variety of sources to customize the pages for the reader. You might see the same news article show up on the sites for multiple different news outlets. This is called content reuse. The goal is to get maximum use out of each content component. Similarly, VR-Forces supports many strategies for reusing scenario components. Using the same terrains for many different scenarios is an obvious case, but for this tech tip we will focus on ways to reuse scenario content – simulation objects and tactical graphics.

VR-Forces 4.6: User-Defined State Properties

Simulation objects in VR-Forces have many state properties, such as speed, heading, altitude, force, and so on. You can set many of these properties using set data requests. In past releases, if you wanted to add a new type of state property, you had to use the VR-Forces Toolkit to write a plug-in or update the application. VR-Forces 4.6 lets you add new state properties without writing code.

Tag – You’re It

During the time between VR-Forces releases, as we work with development versions that have all the new features, we get used to the usability improvements that we’ve added. When we have to go back and use a prior release, the usual reaction to the old version of whatever function has been updated is, “Darn, the old way of doing things is so annoying (by comparison)!”

One of the new usability features in VR-Forces 4.6 is a revision to filtering the object creation palettes. In VR-Forces 4.5 and prior releases, you could filter the object list by selecting the force and category in drop-down lists. Lists are OK if there aren’t too many options, but if you have to scroll, they can be annoying. And even short lists take longer to use than icon bars. In VR-Forces 4.6 we have replaced the drop-down lists with quickly accessible icons.

Light Points

Pilots rely on visual inputs the most to orient themselves in flight. Because vision is so important, night flying can introduce new challenges – limited eyesight, night illusions and light blindness. To combat these issues, pilots train to use a consistent, regulated set of lights (to indicate approach, threshold, etc) to help guide them through darkness, identify where they are, and assess how fast they are moving.

High Performance is our Middle Name: MÄK RTI Performance Blog 1

Although there are many criteria for evaluating and comparing RTI implementations, one of the most important is performance. Choosing an RTI that maximizes throughput and minimizes latency, bandwidth, and CPU usage can mean the difference between success and failure for an HLA simulation program. 

Performance, however, is a difficult thing to quantify. There is not just one number that defines an RTI. There are many types of HLA exercises with wildly varying requirements. High performance on one exercise does not necessarily mean high performance on a different exercise. How many federates are you using? How many updates per second? Are you using a WAN configuration? Are you using any of the services such as DDM or time management? Are you using a Java or a C++ federate? Are you using HLA 1.3 or HLA Evolved? 

The answer to all of these questions can have significant effects on performance. In order to provide the flexibility that meets the needs of most users, an RTl’s configuration options must be robust. It should support the needs of most users out of the box. It must also provide the ability to reconfigure performance capabilities for the exceptional cases, if necessary.

Rapid Scenario Creation in VR-Forces: Now with Chain Guns on Helicopters

A common question from people who are new to VR-Forces:“How easy is it to create new scenarios in VR-Forces?” It’s a good question to ask when you are evaluating CGFs. The answer is always: &ldquoIt depends.”

There are obviously some very complicated scenarios you could dream up that would make scripting them quite complicated and difficult. That said, most scenarios are very easy to script. At the end of this post, you’ll watch a scenario with a helicopter flying over some mountains - I whipped this one up in about three minutes. It runs a bit faster than real time, so you can enjoy it in about one minute or so.

After I create the scenario, I slow it down, play it, and show some of the new 3D/2D integrations that are making VR-Forces 4.0 so popular.  As a bonus, I also demonstrate a new feature coming to VR-Forces 4.0.4 in June. We’ve overhauled our machine gun model and added chain guns to helicopters and other vehicle types, which is something customers have been asking about for a long time.

VT MÄK Announces the Release of RadarFX SAR Server 1.0

We've just launched RadarFX, our new Synthetic Aperture Radar (SAR) simulation and visualization product! We built it in conjunction with our partner, JRM Technologies.

In the real world, a SAR sensor is typically attached to an aircraft or satellite.  A SAR system generates photograph-like still images of a target area by combining radar return data collected from multiple antenna locations along a path of flight. Requests from users on the ground define the target area to be scanned, and other parameters used to generate and return the image.

VR-Link for Unity

We are almost ready to release our beta version of VR-Link for Unity - an HLA/DIS Interoperability module for the Unity Engine!  The official 1.0 release is scheduled for late February.  Meanwhile, you can see a quick demo video here.

On the right, you’ll see a helicopter flying a route in VR-Forces. And on the left, you’ll see that same helicopter being reflected in real-time into a Unity-based sample application - over HLA through the new VR-Link for Unity asset.  For this demo, we used Unity’s well-known "bootcamp" sample terrain, which we also loaded into VR-Forces by exporting it as a height field and image.  And through VR-Link for Unity’s model-mapping GUI, we mapped the HLA entity type to a pre-existing Unity helicopter asset.

VR-Link for Unity gives you access to HLA/DIS objects and interactions directly from Unity’s standard C# scripting and development environment, so that your Unity applications become natively HLA and DIS compliant.  But since the module is built on our traditional C++ VR-Link libraries, it supports all the various flavors of HLA and DIS and works with any RTI that conforms to the appropriate HLA standards.  You can also leverage VR-Link’s FOM mapping capability to support custom HLA FOMs.  If you’re building M&S applications on the Unity Engine, and are interested in DIS/HLA interoperability, we’d love to hear from you.  If you are interested in participating in our beta program, or even just willing to help by describing some of your Unity-based projects, please drop us a note at This email address is being protected from spambots.

Zoom, Terrain Scaling, Linux support and more coming soon in VR-Vantage 1.3.1!

By Brett Wiesner - We know we needed to get a linux build of VR-Vantage out to customers ASAP but we felt like sneaking in a few more features along the way was a good idea. We will release VR-Vantage 1.3.1 around the end of July with support for Red Hat Enterprise Linux 5 and also some great new capabilities like zoom and terrain scaling.

With zoom, you can magnify the view and see things that are far away without changing the observers location. This is useful for UAV sensor applications, ground based binocular views or even periscopes!

Terrain Scaling is a VR-Vantage XR capability that allows you to exaggerate the height of the terrain in order to get a different perspective of the situation. Don’t know which path is an easier climb or drive? Or maybe you want a clearer picture of the relationship between aircraft and the terrain? Exaggerate the slope with terrain scaling and you’ll find out easily!

Attending SIW, Fall 2011: Take 2

I recently attended the Fall 2011 Simulation Interoperability Workshop in Orlando (with Aaron Dubois -- check out his account of SIW here), which I have been attending since 1990 or so. One of the focus areas for this meeting was the NASA Smackdown, which is a lunar lander and rover simulation event that took place at the Spring 2011 SIW and will again be shown at the Spring 2012 SIW. It is organized by NASA with participation from a dozen colleges and universities around the world. A few more universities plan to attend next year, including Arizona State University. We are providing the RTI and technical support for this event again next year. It is really a great way for future engineers and scientists get familiar with distributed simulation and MÄK is pleased to continue to support it. I also spent some time in the MSDL and CBML product development group meetings. Phase II of MSDL is getting started and the CBML group is just finishing up their Trial Use period for Phase I. We are keeping our eye on these developing standards and may support them in future product versions. If you are at all interested in using these standards in MÄK products, please let us know.

MÄK RTI Performance Blog 4: Individual HLA Services Benchmarks

We’ve talked about Latency and we’ve talked about Throughput in the MAK RTI, but now we’ll get into HLA Services.

One major advantage of the MÄK RTI is its ability to turn HLA services on and off. If you are not using DDM, for example, you can have the RTI turn that feature off to get a performance increase. 

Two things need to be noted when using this feature. First, even with all services turned on, the MÄK RTI is very fast. The test federate could still send over 120 thousand updates per second. That is much more than every simulator that we know of, so users really should not fear leaving all services on. Second, every service has its own overhead cost, as is shown in the following chart:

Configuring VLC to receive video streams with low latency

Last week you read all about setting up buffers in VR-Vantage to best suit streaming video. This week I’ll talk about configuring VLC to receive video streams with low latency.

VLC is a commonly used application to show received network video streams out of Vantage and is used often in testing. (You can get VLC from their The default settings for viewing network streams in VLC includes quite a bit of buffering to make sure the video plays smoothly. Sometimes you want to see the video with as little latency as possible, which will require changing a few settings.

Tuning your GPU for VR-Vantage

Many IGs are targeted to one environment. IGs designed specifically to provide the correct cues to high-flying-fast-jets don’t do so well in first-person-shootouts. Truck driving simulators don’t generally render the water well enough for maritime operations. Part of this is due to the choices in the content and part is the tuning of the IG and the graphics processing unit (GPU).

We’ve designed VR-Vantage IG to render beautiful scenes in any domain "“ air, land, and sea "“ and to fit into your simulation architectures. Version 2.0 has concentrated on both beauty and performance so you can get the most out of the graphics card.

Graphics cards these days are awesome. They take a steady stream of data and turn it into beautiful pictures rendered at upwards of 60 times each second (60Hz). To pull it off, the GPU computes color values for each pixel on your display. A 1920x1200 desktop monitor has over 2 million pixels and at 60Hz, thats 120 million color values. A lot of processing goes into each pixel so that collectively they form a beautiful picture. AAA game development houses do the work to configure the graphics card for all their target platforms; you, as a system integrator, have to do the same thing for your training customer.

Partner integrations with MÄK Products

On a quick walk around the show floor here at ITEC 2012 in London, I was excited to see the number of partners and other product vendors demonstrating new integrations between their products and ours:

1) Antycip Simulation is demonstrating a new dynamic ocean visualization plug-in to VR-Vantage, based on their MyOcean3D technology.  This plug-in generates realistic-looking waves by using fast-fourier-transform techniques to generate a dynamic height field, encoding the height field in a texture, and passing the texture to custom shader code running on the GPU.  The shader supports vertex displacement both vertically (for crests and troughs) and horizontally (for curling and breaking wave tips).  In the demonstration, a ship simulated by VR-Forces bobs and rocks realistically on the waves.  This is accomplished through a dynamic form of“ocean clamping&rdquo, where a simple physics model is run in VR-Vantage to offset the ground-truth positions and orientations published over HLA by VR-Forces.  The MyOcean3D plug-in to VR-Vantage is already in use at one customer site, and we are interested in hearing whether you’d like to see this become part of the standard product offering.

2) Discovery Machine is demonstrating a brand new integration between their Knowledge Service Modeler AI software, and our VR-Forces CGF.  With the Knowledge Service Modeler, users can construct strategies in a graphical language that is: accessible to a wide range of users; hierarchical in nature; object-oriented; fully reflective; and easily integrated into existing systems.  In their demonstration, Discovery Machine is showing how users can quickly build complex and high-level behaviors in their editor, and immediately assign those behaviors to VR-Forces entities in an interactive simulation environment.

MÄK RTI 4.4 is finally here!

We are pleased to announce the release of MÄK RTI 4.4, a major feature release that significantly improves performance, as well as adds several new features. 

While MÄK has always focused on performance with our RTI, over the last year we doubled our efforts. Version 4.4 is the second major release with significant improvements in performance. For this release, we have overhauled the message sending and receiving process to dramatically reduce the time to process incoming messages from the network while significantly lowering CPU processing time. Additionally, we have separated the sending and receiving of messages into separate threads so that performance will not be affected when either one of these is heavily taxed. To better understand what makes the MÄK RTI the fastest RTI on the market please read this.

We didn’t stop with performance: you can now use the MÄK RTI with FOM Modules in Lightweight Mode and international customers can now easily translate the text found in the RTI assistant to target the local language.

How do Web & Mobile technologies fit into Modeling & Simulation?

We’ve been busy this year learning the how’s, what’s, and why’s behind web & mobile technology in the context of the Modeling & Simulation community. But we’re not finished - we want to open a conversation with you to hear your thoughts on how Web & Mobile technologies are affecting Modeling & Simulation.

On October 8, we’ll be hosting our very first Web & Mobile Virtual Symposium. What is a Virtual Symposium? Back in the day, the ancient Greeks hosted symposia to meet and discuss philosophy, politics, and matters of the heart. Back then, people had to physically attend the symposium to be face-to-face. On October 8th, we invite you to come virtually using Zoom "” a web-based video conferencing app.

We really want to meet face-to-face, so for this meeting you’ll have to have a video camera and access to the internet. I know that this is a challenge for many people in our industry, so we’ve scheduled the symposium for 12pm US Eastern time; we hope that you can take a break for lunch if you are on the East coast, go to work late if on the West coast, or join us after work if in Europe. If joining on your work laptop isn’t an option, consider downloading the Zoom App on your mobile phone and finding a quiet place outside your office to connect with us.

MÄK’s DI-Guy Makes Driving Simulations More Realistic with Intelligent Humans

NADS miniSim driving simulator uses DI-Guy to inject realism into its driving environment

The recent holiday season marked the one-year anniversary of DI-Guy joining the MÄK team "“ and what a year it has been! From increasing DI-Guy performance and ease-of-use, to developing new ways to control characters, to building more realistic character simulations, and to creating much more content out-of-the-box, 2014 has been the year of DI-Guy.

With such a strong year in the records and such a strong product on the shelf, it makes sense that the National Advanced Driving Simulator (NADS) trusts DI-Guy’s human character simulation in its NADS miniSim„¢ driving simulator.

MÄK RTI Performance Blog 5: Bundling and Compression Benchmarks

If you’re just joining us in this 5 part blog series, welcome! Check out the previous few blogs describing the goal of this series, Latency benchmark info, Throughput benchmark info, and HLA Services benchmark info. 

In addition to turning services on and off as noted in my last blog, the MÄK RTI provides a few ways to reduce the traffic in the network. The two most commonly used methods to do this are bundling and compression. The ideal value to set both of these features varies by the type of simulation being done. Thus it is best to understand their effects on traffic to use effectively. The following graph shows the effects of bundling on network throughput:

The above graph shows our test application with message bundling turned on and off. For this test, the bundling was set at the default 1400 bytes, or just a little under the UDP packet maximum. We also show bundling at 5,000 bytes for comparison. A cursory look at the graph will show a significant speed improvement on small message counts. The improvements then start decreasing until you actually get a small penalty under medium message counts. Once messages become bigger than the bundle value, bundling stops occurring and the performance results are the same as not bundling at all.

Promoting Open Streaming Terrain For Modelling and Simulation at IMAGE and NDIA

By Brett Wiesner - Recently I gave a presentation at IMAGE 2011 in Scottsdale, Arizona and at an NDIA meeting in Fairfax, Virginia on the benefits of Open Streaming Terrain (OST). I thought I’d share just a brief synopsis of that here.

Terrain databases are an important part of any simulation and there are four main approaches for building terrain databases. You have hand modeled terrains that are built by artists and 3D modelers. There are tool generated terrain databases that are built by terrain generation tools. You have direct from source terrains that are constructed on the fly from source data in the client application. And finally you have streaming terrain, where content is streamed from a sever to a client directly. Each of these terrain approaches has its advantages and drawbacks.

Open Streaming Terrain (OST) is a kind of streaming terrain, where the data (elevation, imagery and feature data like roads and building footprints) is streamed from a server to a client using open standards. It’s the open standards thing that’s the important part. See, by using WMS, WFS, TMS or any of the open standards looked after by an open governing body like the Open Geospatial Consortium (OGC) or Open Source Geospatial Foundation (OSGeo) you can build an application that“talks” to other compliant applications and can take advantage of petabytes of free (or fee) source data thats out there on the internet right now.

RTI 4.0.4, VR-Link 4.0.3, and the HLA Evolved API

By Aaron DuBois - The MAK RTI version 4.0 was released on the same day that IEEE officially released the IEEE 1516-2010 standard, otherwise known as HLA Evolved. We were very excited to be able to fully support the new version of HLA from the very first day the standard was out. The down side, however, is that we did all of our development for RTI 4.0 before the standard was finalized, and even at the very end there were minor tweaks happening. Unfortunately we failed to capture the very last change made to the C++ API. As a result, versions 4.0-4.0.3 of the MAK RTI were built against a nearly-final version of the C++ headers, which means that those versions are not quite compatible with the final version of the specification. The new release of RTI 4.0.4 fixes this, and is now built against the final version of the header files.

The final change that was not included in the previous RTI versions was related to a defect in one of the final draft versions of the specification. We actually wrote about this defect in a previous blog post. The problem was with the createFederationExecution RTIambassador methods. There were three variations of this method, each with different input parameters. Some of these parameters contained default values, and as a result there was an ambiguity between two of the variations. We mistakenly thought that there hadn’t been time to get a fix for this ambiguity into the spec, but apparently it did make it in after all. The third variation was renamed to createFederationExecutionWithMIM.

So what does this mean? If you are an RTI customer, but are currently using HLA 1.3 or 1516-2000, this doesn’t affect you at all. The new version of the RTI contains a few bug fixes, so you may want to upgrade anyway, but the HLA Evolved API change won’t be a problem unless you decide to move to the new standard. If you are using HLA Evolved, however, we strongly recommend that you upgrade to the new release and recompile your federate against the new header files. If you were using the third variation of createFederationExecution you will also need to edit your code to use the renamed method. Otherwise, no code changes are necessary. Once you recompile your federate, it will then be truly compatible with the final version of the HLA Evolved specification.

Transportation Research Board’s Annual Conference

We’re here at the Transportation Research Board’s (TRB) annual conference in Washington D.C. with transportation professionals from around the world; we’ve seen members of federal, state, and local governments, along with plenty of researchers from universities.

In this exposition of very robust and specific traffic simulations, MÄK’s web-based traffic simulation, TurboTraffic, is making quite a splash. The ability to quickly define traffic flows on the road network (provided in the cloud from OpenStreetMap), assign a volume of traffic, and then immediately see cars flowing into intersections is causing people to think of new applications. This "quick sketch" style lets non-experts create traffic where they previously would have hired a traffic consultant or simply gone without.

DIS 7 Extensions with the Attribute PDU

DIS 7 brought a large number of improvements to the standard. Two of these improvements, however, stand out above the rest due to their flexibility in supporting all sorts of simulators and not just specific use cases. The first of this improvement is heartbeating for specific types of entities, which I covered in a past newsletter, so let’s move on to the second major general improvement: extensibility.

The Attribute PDU is a new type of message in DIS that works much differently than other PDUs. This PDU is not meant to be used alone and it contains extra information about an existing PDU. For example, say you want to add new parameters to your entities. You can now create an attribute PDU with those parameters and bundle it with your standard entity message. The DIS 7 standard also comes with tens of new record types for all sorts of new data.

Unfortunately, the actual implementation of Attribute PDUs is very confusing. You can attach this PDU at the end of an existing message for one type of effect. You can also send it separately with an identifier. Or you can even send an attribute PDU that affects multiple PDUs by itself. In order to be compliant with DIS 7, all three options need to be managed. Luckily, we do that for you. All you have to do is fill out your data and add it to your object.

Best INTEL Processor For Mid to High-End Gaming PC

Best INTEL Processor For Mid to High-End Gaming PC

Intel offers several processors that are widely held to be some of the best CPU's around for PC gaming systems. They exist in a natural progression of both performance and price, but that doesn't mean the most expensive is necessarily the best choice. It's all about what you plan to do with your system and what your long and short term budgets are. For near term budgeting, consider the reasonable life expectancy of your next PC purchase before you will probably want to replace it. For casual gamers purchasing a top of the line machine, this could be 5+ years. On the other hand, casual gamers may find it just as satisfying and cheaper to purchase a middle of the line machine now and replace it with whatever is middle of the road 2-3 years down the line. Hardcore gamers may find themselves upgrading more often, and should budget accordingly.

So what's the best Intel gaming processor? Let's take a look at them:

MÄK RTI Performance Blog 2: Latency Benchmarking

Welcome to the first topic of our multi-post series highlighting specifics about the performance of the MÄK RTI! We’ll start with the topic of Latency, or the amount of time it takes for data to reach its destination. 

Much of the literature on distributed simulations indicates that latencies of up to 30-100 milliseconds are tolerable without losing the feeling of real-time interactivity. Even a 3D graphics-based application running at 60Hz has 16 milliseconds in which to compute and draw each frame, meaning that latencies of 5-10 milliseconds may not even effect the time at which a particular event is drawn. Meanwhile, typical latencies for the MÄK RTI are closer to 100 microseconds on our gigabit network "“ fast enough to meet the needs of even the most sensitive real-time simulations.

VR-Forces 4.3 Simulation Model Set Enhancements

In VR-Forces 4.3, we’ve made a number of enhancements that are not immediately obvious, but are still very useful if you know how to take advantage of them. In this post I’ll share some tips on how to make use of the improved Simulation Model Set (SMS) management that is part of VR-Forces 4.3.

For those who don’t already know, a Simulation Model Set (SMS) in VR-Forces is the set of configuration files that defines the entities and objects available for creation in a scenario. This includes everything from their names and type enumerations to their behavior logic and physical movement dynamics. An SMS is typically modified using the VR-Forces Entity Editor tool.

VR-Forces ships with some preconfigured SMSs with hundreds of objects to use in scenarios, however, it is quite common for customers to add specific models, or to modify the shipped VR-Forces models to suit the needs of various projects.  In the past, this was most often done by editing the default SMS in VR-Forces directly, or by copying it wholesale and making edits to the copy. Both of these options lead to significant upgrade work when moving to a new version of VR-Forces where parts of the default SMS were edited, since the changes have to be merged.

MÄK at the Singapore Air Show - Take 2

You have to hand it to Singapore. They sure do know how to put on an Air Show. There’s nothing like holding a pleasant conversation with customers or colleagues only to be interrupted by the roar of an F15 jet passing right in front of the door then ascending like a rocket straight into the clouds. Very impressive. 

MÄK is presenting in two locations at the Singapore Airshow. Our COTS products are on display at the TME Systems booth and our Battle Lab (a.k.a. ISR Lab) is in the Ideas section of the ST Engineering booth. 

The Battle Lab is getting a lot of attention. Some are attracted by the analysis graphics shown in the AGI SimMetrics display and others by the Simulated Video streaming from the UAV’s sensor IG through the comms model to the Ground Control Station.

MÄK CST Fills the Command and Staff Training Capability Gap

Simulation has become an accepted, routine, and critical method of training militaries worldwide. Many nations have invested heavily in large simulations for wargaming, however there is no "one size fits all" training simulation. Software that may be appropriate for one nation may be too cumbersome, resource intensive, and unmanageable for others. A low-overhead simulation system will address a nation’s wargaming and constructive simulation requirements, while also being much more economical in terms of procurement, training, and sustainment. 

MÄK CST fills the Command & Staff training capability gap. It combines the user-friendly features of a game with capabilities of the larger, more complex simulations to help trainees learn how to make stronger battlefield decisions. Because of its flexibility and ease-of-use, MÄK CST can be used in the classroom, in the simulation center, on deployment, and at home stations.

The MÄK FOM Editor: At Home on the Web

Maybe you’ve seen the newest addition to the MÄK Product Suite: the MÄK FOM Editor. Some of you may have been surprised to see it’s a web page "” most modeling and simulation applications are heavyweight desktop applications.  MÄK is leading the industry by bringing lightweight and powerful web applications to the modeling and simulation community. For this article, I want to describe why we choose the web for the MÄK FOM Editor and discuss some of the technologies that enabled it. I will also talk briefly about security and what is happening to your data when you use it.

At home on the web

We chose to develop the MÄK FOM Editor as a web-based application because we could do it quickly with less hassle than a standard desktop application. First, we could develop it once and deploy it on any platform for which our customers had a web browser (we assume you all do). Second, since there is no heavyweight deployment process, it means we could release new versions of it "“ with bug fixes and new features "“ almost every day! While the former makes development cheap enough , the latter is really the best part. Within a day of using it, one of the first users reported a few minor problems and within hours they were resolved.

Windows 7 and RTI slow down

Recently we have been seeing widespread Windows 7 adoption by our customers, we are internally moving to it too. However, we have noticed some very strange behavior on Windows 7 with some of our applications.

The most significant problem we have run into is extremely slow startup times for the MAK RTI. This problem is usually obvious; the RTI Assistant will take between 3 and 15 minutes to load.

While its loading you will just see a blank console window. HLA Federates may take an equally long time to load because they are waiting for the RTI.

What is this Logger Tape?

Interoperability is hard. It is hard because there are a myriad of open standards out there, as well as multiple protocols, operating systems, and, of course, requirements. At VT MÄK, we understand this. To help, we have always tried to support the widest variety of configurations that we can. All of our products support four different DIS versions, three different HLA versions, and a plethora of FOMS, operating systems, and compilers. VR-Exchange expands this even further with DDS, TENA, and many other protocols.

Generic Attributes and Parameters in VR-Link 5.1

Among it's many other new features, VR-Link introduces generic attributes and parameters for version 5.1. Generics are a way of accessing extended information in your FOM that is not normally supported. For example, lets say your FOM, based on RPR, contains an extra attribute on entity objects called "RadarSignature." Once generics are enabled in VR-Link, all you have to do is ask for your data:

VR-Link: Not Just for C++ and C#

Now that VR-Link for C# is released, we are excited to build new simulations on top of C#. I personally find C# to be fantastic to work with, so I can't wait. But even more interesting is that VR-Link is actually built as a CLI (Common Language Runtime) library.

The CLI is an intermediate language that can be used to build applications on any other language that conforms to the CLI standard. There are many. As of this writing, Wikipedia ( lists 32 separate languages that can interface with a CLI library. This includes scripting tools such as Python, PHP, and Ruby, purer languages such as Eiffel, and commonly used simpler languages, such as Visual Basic! Our customers are no longer bound by language limitations and will now be able to choose the language strictly based on which one is more useful for the job. You can even mix and match as you please.

My HLA federates aren’t talking to each other!

Because HLA has so many configuration options, it can be frustrating to learn that your system isn’t communicating when you think everything is set up correctly. The MÄK RTI team works very hard to make it as easy to use as possible, but sometimes things go wrong. HLA federations can be very complicated.

Luckily, the new MÄK RTI 4.2 provides a revamped RTI Assistant that will help you find the problem and fix it faster than ever. In this blog, we will identify and attempt to remedy the most common problems.

Are all the federates correctly connected?
Double clicking on your RTI Assistant tray icon opens up the Federations View.

RTI RID Configuration Tips: Part 2 "“ The Advantages of MTL

This is part 2 in my series of blog posts on RTI RID configuration tips. Each of these tips, unless otherwise noted, works in HLA 1.3, HLA 1516-2000, or HLA Evolved. Take a look at part 1 HERE, and stay tuned for future posts in this series.

RID files are written in Lisp

The RID file is written in MTL. MTL stands for MÄK Technologies Lisp. MTL is basically a limited form of the Lisp programming language. The primary purpose of the RID MTL file is to set specific variables which are parsed by the RTI’s MTL parser and loaded into configuration settings. The same goal could be achieved using other formats such as XML (another popular MÄK configuration file format), but there are advantages to MTL.

The first important thing to understand is the difference between the setq and setqb commands. The "˜b’ in the setqb command stands for "bound". This command is used to set the bound variables that are recognized by the RTI. So the only variables set using setqb should be those that are documented RID parameters that are accepted by the RTI. The setq command, however, can be used to set any temporary variables you want that can be used in RID processing. Why would you want to do this? Well, used in conjunction with other features of MTL, this can make your life just a little bit easier. Here’s an example:

RTI RID Configuration Tips: Part 1:“ RID Consistency Checking

As anyone who has edited a RID file for the RTI can tell you, there are a lot of different parameters available to customize how you want the RTI to function. It can be pretty overwhelming. Over the years we’ve tried to make RTI configuration as simple as possible, while still preserving the ability for users to get their hands dirty with the nitty-gritty details of RTI operation. To this end we’ve tried to choose default settings that make sense, and we created the RTI Assistant to allow you to quickly and easily edit the most commonly used connection parameters from a simple GUI. Hopefully that helps many of you stay out of the RID file as much as possible, but chances are at some point you will have to take the plunge and delve into it. To help you out when that day comes, I’ll be writing a series of blog posts with tips and tricks that will hopefully come in handy. I’m not going to go through each parameter in detail. Instead I’m going to cover some general configuration techniques and tips on debugging potential RID issues. If you have a question about individual RID parameters, please see the back of the RTI Reference Manual or drop us an email at This email address is being protected from spambots. You need JavaScript enabled to view it.. Unless otherwise noted, all of the tips I’ll be discussing can be used for all HLA versions: HLA 1.3, HLA 1516-2000, and HLA Evolved.

Coming: Lines sure to get your terrain embed

Okay, the title this week was a little weak, it was an attempt at a good pun on par with the Economist’s discussion of the S&P Downgrade:“Substandard & Poor: AAAaaargh! (ARTICLE)”. Sorry"¦

As many of you know, MAK’s vision of the future of terrain is a combination of live streaming source data coupled with high resolution insets. The idea is, you still need to obtain (or create) high fidelity terrain databases largely by hand. However, the technology to generate moderate fidelity terrain from streaming source data (imagery, elevation, and feature data) is getting better every day. So, the world you want is one where the hand generated terrain is smaller and smaller and well blended with the source data providing the rest of the world. In this world you may generate a DB for your base of operations, and a DB for the area where you will insert after a helo to fight. However, the space between the base and the extraction point will be procedurally generated to appear to be high fidelity from the perspective of the helicopter. Such blending should let you go from space to someone’s dining room table. In the three pictures below we embed the hand crafted OpenFlt DB "VR-Village" into the broader world as supplied by VR-The World ( (Yes, the transition is smooth and beautiful).

Do I need a new graphics card?

Frequently we get questions about hardware requirements for customers who are trying to use VR-Vantage as an IG for a specific program. Typically, the customer is looking to achieve 60 frames per second (FPS) in VR-Vantage and their scene is rendering slower than they would like/expect. They have read the MÄK Blog about minimum hardware yet didn’t find the answer they were looking for.

Over the years, many of us have been conditioned to assume that buying newer/better hardware will yield better performance; if your performance isn’t up to snuff, just buy something newer. This often works – new GPUs are released yearly, often with phenomenal performance improvements. The cost for this new hardware is low compared to the total program cost, so upgrading can make sense. That said, most terrains used in the Modeling & Simulation community aren’t particularly complicated and so should run really fast even on old hardware. So how can you figure out if it’s your terrain that is slowing you down or if it’s your graphics card that is the culprit? This blog will try to answer that question for you.

To understand where your bottleneck is, you need to understand if your application is CPU or GPU bound. For this blog I will use the term “CPU” to mean not just the physical processor, but also the process of organizing and passing information to the GPU. Simply put, VR-Vantage can be bottlenecked in many places: collecting information from the network, updating the scene graph, sending information to the GPU, or the GPU itself may be bottlenecked trying to render the actual scene. Of these possible bottlenecks, upgrading your video card will only help the final case. That means if your scene is slow for any reason besides the final render step, you need to optimize your scene’s content and configuration, not by buying a better graphics card.

Do I need a new graphics card? Part 2

A week ago, I wrote a blog entitled “Do I need a new graphics card?” to answer the common question: Will I get better performance if I just upgrade my graphics card? In the blog, I discussed the difference between CPU and GPU bound scenes, and made the point that if you are CPU bound, getting a new graphics card will not help much. Typically scene performance will improve more with better terrain organization. 

While that is all true, there is one additional problem you may encounter that will spoil performance and can be addressed by upgrading hardware: running out of video memory. VR-Vantage 2.0.1 now tracks your total video memory, how much you are using, and if any of your textures have been pushed out of memory (evictions). Once you have consumed all of your video memory, the card will start swapping textures off the card and into the system memory. This is incredibly slow and will seriously affect frame rate. Scenes that were fast may all of a sudden have a 100ms draw time. 

To see how your scene is performing, turn on your Performance Statistics Overlay (found in Display Settings -> Render Settings).  You would want to see something below 80% usage. As you move around in your scene, if the memory consumption gets up to 100%, or you start seeing Evictions, then your performance is being seriously affected by a lack of memory.

Parallel Publishing in VR-Link

VR-Link 5.1 has put a heavy emphasis on performance. The MÄK Engineers have gone through every bit of VR-Link to find hundreds of speed improvements in the already fast libraries. There comes a point, however, that most of your speed improvements are going to come with multi-threading.

VR-Link now includes multi-threading classes that allow you to update publish your DIS and HLA objects in parallel, greatly speeding up that side of the simulation. But don’t worry, we have abstracted out most of the complexity required to multi-thread, and your code does not have to increase in complexity at all.

The trick to this simplicity is that we have now created a DtPublisherContainer, a class that can tick all the publishers at the same time but can be used in a single threaded environment otherwise. For example, if your code before looked like this:

HLA Ownership Management in VR-Link 5.1

Transferring control in simulations is a complicated dance. Both the relinquishing and the receiving simulations have to agree in principal and then exchange lots of complicated transactions to make the exchange. The complexity leaves most who attempt it frustrated and hopeless.

It doesn’t have to be that way. In VR-Link 5.1, MÄK offers you a technique to make the transfer of objects pre-approved and thus easy. Each participating simulation starts by agreeing to take any objects offered and agreeing to relinquish any objects asked for. With the approval steps out of the way, only a single message is needed to take control of another simulation’s airplane, for example. Similarly, with a single message your simulation can give back control when you are finished. We’ve included examples in VR-Link to illustrate this technique. So give it a try "” it’s actually kind of fun.

VR-Link for C# loads all protocol-specific material at runtime

If you’ve been playing with some of our VR-Link for C# examples, you might have noticed something strange. We usually include one example for each networking protocol, so you get F18DIS, F18HLA13, and F18HLA1516e.

But our C# examples do not do that. There is just a single F18Sharp executable. Don’t worry, we didn’t suddenly decide to drop all our networking standards. In C#, we have slightly changed the VR-Link interface to load all the protocol-specific material at run-time instead of at compile time.

Now you don’t even need to recompile to get all your protocols. You can define which protocol you want in your run-time configuration, or even command line arguments.

"Your software has crashed for unknown reasons..."

As a software engineer, just writing that line brings my heart rate up. HLA in particular makes things a little harder because of the sheer number of exceptions that HLA throws, even for non-exceptional reasons. In this article, we will discuss two minor additions to VR-Link 5.0.1: One that helps find the error and another that helps you recover from an error gracefully.

First things first "” finding the error. Have you ever had a crash (hopefully not too many) in VR-Forces and encountered a little dialog asking you to save a memory dump? If you send that memory dump to us, we can analyze the VR-Forces source code and find the cause of that crash. This is actually a fairly simple feature that Windows provides. To make it even easier for you, however, we now have a simplified version of this in VR-Link that you can implement in your own applications.

DtMinidump miniDump("ApplicationName"); //Enable mini-dump.

How to handle disparate DIS versions

Now that VR-Link 5.0 is out and we have added support for DIS Version 7, you might have questions about compatibility between DIS versions and VR-Link. In a nutshell, if everyone is using VR-Link 5.0, there will be no compatibility problems. If you have systems not using VR-Link, or using an older version of VR-Link, then you might have some situations arise.

DIS Version 7 is not fully backwards compatible with previous versions of DIS. If you are sending DIS 7 PDUs, there is no guarantee that the other systems in your exercise will be able to read them. For this reason, by default, VR-Link 5.0 still sends DIS version 6 PDUs. This means that upgrading to VR-Link 5.0 will not suddenly make your exercise incompatible.

If you want to send DIS Version 7, you can set the global variable DtProtocolVersionToSend to 7 (this is defined in the file pdu.h). Now, you are sending DIS 7 compatible PDUs. You can also, of course, set that value to any number between 4 and 7 to send a specific version of the protocol. You can even do this at runtime using the command line if you are using our included command line interface:

DtVrlApplicationInitializer appInit(argc, argv, "VR-Link Application");

If you are parsing the command line (or loading a VR-Link configuration from a file) simply typing "--disVersion 7" as a command line parameter will force your application to send DIS Version 7 messages.

Receiving legacy PDUs into a VR-Link 5.0 version should give you no problem at all. VR-Link has always been able to support receiving multiple protocol versions even in the same exercise. For years, we have been able to read versions 4-6 of the DIS protocol. Now, you can read versions 4-7. This is regardless of what version you are actually sending. (As an aside, this is also true in HLA where you can mix HLA 1.3 federates with HLA Evolved federates.)

There are two values that define what DIS version you can receive: DtProtocolVersionToRecvMin, and DtProtocolVersionToRecvMax. Both are also located in pdu.h. In nearly all situations you should not need to change these values, since by default they are set to the lowest and highest values that VR-Link can provide.

Those two values exist in older versions of VR-Link as well, although they are set to 4-6 instead of 4-7. If you feel up to it however, you can take an older version of VR-Link and tell it to read DIS Version 7. It will not understand new concepts, but in some cases it understands enough to be able to communicate with newer systems.

Keeping pace with modern programming languages

Programming languages have been evolving since the first computer was created. Early languages, including Autocode, FORTRAN, and FlowMatic, made way for many of today’s modern languages. The era of the C language introduced better structure and access to low-level system functions and devices. Then came C++, adding object-oriented programming constructs. Now we have a whole class of simple, modern, general-purpose, object-oriented programming languages, like C# (pronounced C sharp), that are gaining popularity.

VR-Link has been with you since the beginning and we plan to be with you to the end. So "“ drum roll please "“ we are excited to introduce C# support for VR-Link! Because our C# implementation of VR-Link is built as a Common Language Infrastructure (CLI) library, you can build your applications using C# or any other language that conforms to the CLI standard. There are currently 32 separate languages that are a part of the CLI standard, including Python, Ruby, and Visual Basic, as well as functional languages like F# and Lisp. (Functional languages provide an incredible amount of power when manipulating objects or groups of objects - read more about programming with F#.)

MÄK wants to make your life easier and we hope that by adding C# and other CLI-compliant languages, we have. If you have questions or requests, get in touch with us at This email address is being protected from spambots. You need JavaScript enabled to view it. (or leave us a comment below)!

How MÄK’s FOM Editor Handles Differences between HLA 1.3 and 1516 FOMs

Last fall, MÄK introduced our FOM Editor, a web-based application for creating and extending HLA FOMs. The original goal of the tool was to make it easier for people to quickly develop their own HLA Evolved FOM modules to extend widely used existing FOMs, such as the RPR FOM. Once we had a tool that supported HLA Evolved FOMs, however, it was simple to add support for HLA 1516-2000 as well. Both 1516-2000 and 1516-2010 (as HLA Evolved is more officially known) use XML formats and contain a lot of the same information. The formats are a bit different and 1516-2010 added some new things, but there is a lot of overlap.

Until recently we have not had any support for HLA 1.3, but we just upgraded the FOM Editor to import 1.3 OMT and FED files for conversion to HLA 1516 formats. To try it you will need a valid 1.3 OMT file at a minimum, but a FED file is also recommended for a full import. Just drag your OMT file onto the Project page, and once that’s complete, follow it up with your FED file.

Things are a bit different in 1.3 than in 1516. The most obvious difference is that rather than using a single type of file, a 1.3 FOM is defined by a combination of an OMT file and a FED file (neither of which is in XML). That’s a fairly minor difference from the point of view of the FOM Editor, but there are more important differences that don’t become apparent until you delve into the content of the files. Datatypes just aren’t the same in 1.3 as in 1516, and the FOM Editor has to make some assumptions and choices when converting a 1.3 file to a 1516 file. Below is a list of some of the most notable differences between 1.3 and 1516 FOMs, as well as a brief description of how the FOM Editor handles each case.

OMT Diff Tool

I recently had need to compare to OMT files to see what would be required for bridging them using VR-Exchange.  Rather than doing it by hand, which would have most likely been a large waste of time and risked missing something important, I spent a few hours writing a tool that would compare two OMT files for me.

One of the issues of comparing OMT files is that a simple text based diff won''t give you the results you want because there is a lot of semantic information that needs to be compared.

The customer gave me two OMT files and said that they were both RPR FOM based with some extensions. That should simply work with VR-Exchange out of the box. However, using the OMTDiff tool we found that there were several enumerations with the same name, but with different values.  Using this information I was able to quickly create a modified HLA broker for VR-Exchange that intercepts these enumeration values and translates them properly.

Coming Soon to a Federation Near You: RPR FOM 2.0

SISO’s annual Simulation Interoperability Workshop (SIW) will soon be here and as always, a number of us MÄKers will be in attendance.  There is a lot going on this year but one of the most notable "” at least in my (admittedly biased) opinion "” is the meeting of the RPR FOM PDG. Earlier this year RPR FOM 2.0 was successfully balloted, though with a number of comments. A small group of us has been working to resolve those comments and at SIW we’ll be holding a full PDG meeting to vote on final decisions (feel free to join us). That means we may soon have an official RPR FOM 2.0 standard!

Some of you are probably thinking, "What’s the big deal? I’ve been using RPR 2 for years." It’s true, many of us have been. Despite never being officially standardized, draft 17 of the FOM has become a de facto standard, used throughout the world in many important federations. But draft 17 had a number of issues which the RPR drafting group has been trying to address over the last couple of years. Perhaps the most glaring problem was the lack of support for HLA 1516-2000 or 1516-2010 (HLA Evolved). While a number of versions have been produced by different groups over the years, there was no one official version. On top of that we have fixed bugs, inconsistencies, poor datatype naming, and confusing descriptions and documentation. We now even have a modularized version for HLA Evolved. I am happy to say that I believe this is the best version of the RPR FOM yet. I encourage you all to check out draft 20 of both the FOM and the accompanying GRIM (Guidance, Rationale, and Interoperability Modalities) document.

If you are going to be at SIW and would like a higher level overview of RPR FOM history, what we’ve been up to lately, and where we think the FOM is headed in the future, I also encourage you to attend the presentation of a paper I co-authored with Björn Möller of Pitch Technologies, Patrice Le Leydour of Thales, and René Verhage of CAE titled "RPR FOM 2.0: A Federation Object Model for Defense Simulations."

Support Tips #1 "“ Licensing: Maintenance date issues

Every year we receive a number of support questions which have to do with licensing. We hate to receive them, because licensing should be easy! For the most part it is, as many customers never run into any problems at all. However, when a problem does crop up customers frequently feel at a loss.

MAK Support Changes

As many of you know, MÄK has an unorthodox model for technical support. We are proud of how we do support, and believe it’s a key reason why people buy our products (other than the fact that we make awesome products!). In the next few weeks, and continuing over the summer, we will be making a few minor changes to how we handle technical support.

HLA Evolved is Coming!

Good news! HLA Evolved has just cleared a major milestone with the IEEE SAB and REVCOM approving the changes to the HLA Standard. IEEE will now will complete an editorial review and then publish the new IEEE 1516-2010 family of standards. This pretty much means the standards are finalized and will appear on the IEEE website soon.

Design Decision: RTI Federations View and Network Component View


When adding features to a product we frequently need to make design decisions. Often these decisions come after many hours of sometimes heated arguments. Today I want to write about one of the design decisions we made with the RTI, and what its implications for the future are. I want to talk about the two main information dialogs in the RTI Assistant: the Federations View, and the Network Component View.

Design Decision: Where is the rtiexec GUI?

Today I want to discuss a key design decision we made with the RTI in version 3.4: we removed the rtiexec user interface. For many years the MÄK RTI’s rtiexec had two user interfaces: a console and a QT based GUI. In version 3.4, we removed both options and made the rtiexec a simple daemon with no interactive interface.

HLA and RTIs: What’s with all the crazy names?

Frequently people write to support and say“My RTI Crashed!”, or they write "I have 10 federates, and the RTI is installed on Machine X." When I read sentences like these I sometimes cringe. I cringe because RTIs really don’t crash; a component of your RTI crashed. Maybe I cringe because I have been working with RTIs for a very long time.

Support Tips #2 -Tuning the MAK RTI for low latency

Occasionally we receive a support request asking for the latency of a message in the RTI.  Answering these questions is difficult as there are many factors which can affect RTI latency. Not least of these is the network itself and the tick rate of the federate. These are probably the two largest factors in determining latency.

RTI 4.0 and VR-Link 4.0 Status Update

Today I just wanted to provide a status update on our upcoming MAK RTI 4.0 release, and the corresponding VR-Link 4.0 release .  These releases will add support for HLA Evolved to each product. As most of you know, HLA Evolved is the latest version of the IEEE 1516 standard which was released this spring.

The HLA Evolved Upgrade (part 1)

An HLA Evolved compatible MAK RTI is almost ready for release. As we have been awaiting its release we have received a few requests for more information about HLA Evolved, specifically the work required to update a federate to the latest version of HLA. I was always surprised about this because I have always used VR-Link; our plan is to make VR-Link source compatible, so there will be almost no work required to upgrade a federate using VR-Link.

The HLA Evolved Upgrade (part 2)

After you have connected to the RTI and Joined a Federation, your federate will tell the RTI what Classes it will be publishing and subscribing to: these are the HLA Declaration Management Services. For objects, this is done through the RTIAmbassador’s publishObjectClass() and subscribeObjectClassAttributes() respectively. Additionally for Objects you will need to tell the RTI which attributes in the class you will be publishing or interested in. The process is similar for interactions, but with interactions you must subscribe to and publish all attributes.

Flood of Federates Forming a Functional Federation (and Fast)

Recently one of our customers contacted us for consulting on how to setup a large federation that would scale up to 1000 federates. Here is how we setup their federation for scaling to large numbers of federates.

Upon first arriving, we took a look at their Federation Object Model (FOM) to get an idea of what types of objects and interactions they were sending through the RTI and how much data was being used.

Support Tip #3 - Post RTI 4.0 Include Paths

If you have upgraded to a new version of the MAK RTI, you have probably noticed that the RTI include paths have changed. This means that MS Visual Studio project files which worked with pre 4.0 RTI versions likely no longer work. This problem manifests itself when your previously compiling application can no longer find RTI.hh or some other standard RTI header file.

The Multiple Views of VR-Forces 4.0 GUI

VR-Forces 4.0 is getting close to release!  As many of you are aware, we’ve been working hard over the past year to give VR-Forces a whole new GUI based on MAK’s VR-Vantage visual product.  One of the key new capabilities of this GUI is the ability to work with many different views of the scenario at the same time.

Starting VR-Forces

When VR-Forces starts up, it needs to connect to a DIS or HLA exercise. To do that, you need to specify at least a minimum set of configuration parameters. The VR-Forces Launcher provides a graphical user interface for specifying these parameters. It is ideal if you want to run in combined mode (one front-end and one back-end that start together) or in independent mode (front-ends and  back-end are started separately) with just one front-end and back-end.

Pattern-of-Life Simulation with B-Have 2.0

Pattern-of-Life analysis is becoming increasingly important in today’s military. It revolves around the continuous observation of behavior patterns for a population, town, or street. Most people and populations tend to have very distinct patterns in our lives. We get up, brush our teeth, go to work, go to lunch, go home, kiss the kids, and go to bed. Okay, maybe your life is more interesting than mine, but when you think about it in the big picture people in general are fairly predictable. This gives way to the“See something, say something” signs we see in airports. On a subconscious level everyone recognizes patterns in our lives: we wear winter coats when it’s snowing and shorts when it’s hot. When someone is wearing a winter coat and it’s hot outside, you notice it.

VR-Forces 4.0.1: We’re back!

The title today is a bit of a positive spin on a few problems we have had with VR-Forces. Perhaps, we should say“VR-Forces 4.0.1: were sorry, but we will be better.” It’s important to always be honest, even when you make a mistake. With the introduction to VR-Forces 4.0 we were so excited about new visualization, we left out some important features. You let us know we messed up, and we understand. With VR-Forces 4.0.1 we have started to add the features back in, and have put most of the other features on a priority list where they will show up in VR-Forces maintenance releases later this year.

Coming: Extrude your world

Today I wanted to give you another glimpse of some technology which is coming to MAK products like VR-Forces and VR-Vantage: streaming feature data.

Future versions of VR-TheWorld server will be able to load and stream geospatial feature data, including VMAP, .shape, and S57, among others. There are many applications for streaming feature data, but one of the better ones is to use to to generate richer terrains from raw source data. Currently VR-The World, VR-Vantage, and VR-Forces support streaming imagery and elevation source data. Adding streaming feature data will allow for the automatic extrusions of buildings and the placement of line, point, and areal models on top of the streamed imagery. It means when you walk off your embedded hand modeled open flight terrain (See Blog“How to get your terrain embed”), you will still be in a 3D world full of fairly rich objects.

Attending SIW, Fall 2011

Last week a couple of other MÄKers and I once again made the trip down to Orlando to attend the biannual Simulation Interoperability Workshop (SIW). I’m sure many of you are familiar with the workshop, but for those of you who don’t know it, SIW is where people in the simulation industry from around the world meet to discuss the work they’ve been doing in simulation interoperability and develop the standards that the industry uses. This is where standards such as HLA and DIS are developed.

The workshop consisted of the usual presentations and development group meetings. To me, one of the most interesting was the RPR FOM revival meeting. There is a new push right now to restart the RPR FOM Product Development Group (PDG) and finalize the RPR FOM 2 standard. There are currently several draft versions of the standard, but nothing official. As a result, different simulations will end up using slightly different versions of RPR 2. At MÄK, we’ve added support in our products for a few of the more popular RPR 2 drafts, but we are definitely interested in seeing the standard finalized. We’re excited to be part of the RPR FOM 2 standardization effort, and we hope that RPR will continue beyond that as well. After all, the new version of DIS is nearing completion, so the RPR FOM will need to keep up.

SimMetrics “ It’s 10 o’clock; do you know where your children are?

In the next few blogs I want to talk about a new exciting product MÄK is working on with AGI”SimMetrics. SimMetrics is a cool product that uses AGI’s analytics and MÄK’s visualization to model sensors, sensor tracking, the GPS Constellation, and GPS receivers to produce a real time analytical capability integrated with your simulation environment. All of this is done to add high fidelity real time Intelligence, Surveillance, and Recognizance (ISR) capabilities to your simulation environment. To model a high fidelity ISR capability, you need to know where you are and where your targets are. SimMetrics helps you easily do both.

To help you understand where you are, SimMetrics models the entire GPS constellation taking into consideration both your position and the calendar time.

Accurate GPS catalogues are used so if a satellite is off line for maintenance or currently experiencing technical difficulty, two factors which will have significant impact on your ability to know where you are.

Attending the SIGE: Fall 2011

The Aeronautics Institute of Technology (ITA) annually organizes the Defense Operational Applications Symposium (SIGE). This year the event was scheduled between September 27th to 30th. The SIGE, in the 13th edition, is an international event which the main goal is to create a suitable environment for experiences exchange between military and civilian academic, industrial and commercial institutions interested in defense research and development.

This is a conference where papers are delivered and companies such as Latin Media and VT MÄK are able to attend and exhibit today’s latest COTS technology.

ITA is basically a military school/college where a lot of students come to study aeronautical engineering.  There are a number of divisions within ITA, all offering their expertise and specialty.  There is one group within ITA who has a suite of VT MÄK products that we (I) provided them.  It is a collaborative effort with GMU (See attached) where they are developing a C2 application at GMU in Virginia and then this information and expertise is transferred to Brazil.

Logger 5.1 Release Features

Logger 5.1 now features an improved remote control interface (RCI), making it easier than ever for you to control the Logger remotely from your applications, such as After Action Review (AAR) systems and Instructor Operator Stations (IOS). The Logger RCI has migrated from a PDU centric toolkit to an API that mirrors the internal Logger architecture. The interface is designed to support multiple Loggers as if they were a single Logger, which allows for distributing the load among several processors or machines.

An Interesting VR-Link Use Case: Aerial Refueling

The other day I was talking to a customer about an interesting use case involving VR-Link. They are using VR-Link to network two simulations together for Aerial Refueling Exercises. While DIS and VR-Link have both been around for over 20 years, this was the first time that they were used for aerial refueling.  The aircraft involved are moving at high speeds and physically connect to each other during flight. It turns out, this is pretty tricky, which I’m sure most of you have already gathered. Using VR-Link, this customer modified how the messages were sent to make sure the simulation was fast enough to provide adequate training. If you are interested in seeing this in person, the Air National Guard will be highlighting this in their booth at I/ITSEC this year.

Tech Tip:“ Using Spawn and Sink Points to Create Background Traffic

We are working on our demos for I/ITSEC and the Traffic Generation feature in B-HAVE 2.0 for VR-Forces 4.0.1 is proving to be a big help. Jim Kogler has blogged about this feature in his Pattern of Life blog, but to recap, when you add spawn points and sink points to a scenario, VR-Forces automatically creates entities (civilian lifeforms or civilian vehicles) at a set interval at the spawn point. They then move towards a randomly chosen sink point. When they get to the sink point they are deleted. This provides a steady stream of entity traffic that moves purposefully without the need to create plans, assign tasks, create routes, and so on. So I thought I would share some of my experiences with them.

My scenario has 18 spawn points and 18 sink points in a relatively small area. After one minute of simulation, more than 200 entities get created. After four minutes more than 400 are created. So when you plan your scenario, consider how many entities you want (including any entities that have specific plans as the main point of the scenario) and plan the number of spawn points accordingly; otherwise, like the Sorcerer’s Apprentice, you may find yourself dealing with a flood of entities.

All things MÄK at I/ITSEC

It’s great to be back at I/ITSEC for another year"”seeing those familiar faces, a few that I haven’t seen in over 10 years, is a wonderful thing that makes being here a fun and special time.

As far as what’s happening on the show floor, I’ve seen some really innovative visual technologies around. Something that I’m sure fellow MÄK bloggers have commented on is how well our streaming terrain is being received. It seems like every time I turn around there’s a new crowd asking for a terrain demo.  I haven’t seen anything yet that is comparable to our streaming terrain"¦perhaps this explains our popularity.

Last night was a fun night for MÄK as well: instead of putting on the ChowdahFest as we do every year, MÄK decided to put on a series of events - the MÄK Fest. Last night’s event included lots of fun at “Howl at the Moon”, a renowned dueling piano bar in Orlando. It was fun to see all of our MÄK staff, customers, and I/ITSEC friends hanging out, wearing cowboy hats (the funny hat trend continues), and having a great time.  I’m looking forward to seeing fireworks tonight at Epcot and doing some karaoke tomorrow night at Orlando CityWalk!

MÄK: Seeing Fireworks at I/ITSEC

After another busy day on the show floor yesterday, MÄK let loose for the second night of our first ever“MÄK Fest.” We sent two busloads of MÄK staff, customers, partners, and I/ITSEC friends to Disney’s Epcot to enjoy a lakeside fireworks show, complete with dinner, drinks, hot chocolate, and the classically beautiful Disney Christmas décor.

While we enjoyed ourselves, I had the chance to speak with many different groups of customers. While the most common topic was the state of the economy, it was encouraging to hear how creative everyone is becoming to meet end-user requirements on reduced budgets. I was gratified to hear how MÄK is playing a role in meeting these challenges with our COTS products and solutions.

The evening was a complete success and I’m looking forward to tonight’s party at "Rising Star "“ Universal CityWalk." It will include a bit of classy karaoke, including a live band and back-up singers. If you’re at I/ITSEC now, stop by our booth (#2549) to pick up your tickets!

MÄK Tools in the NextGen Environment

When preparing fo the ATCA conferences this year, we wanted to show how MÄK tools can be used in the NextGen environment.  One example we showed used the VR-Exchange protocol translator to build a bridge connecting ADS-B traffic to simulation standard protocols, such as DIS and HLA Evolved (High Level Architecture).  By creating a custom Broker for VR-Exchange using the toolkit, it allowed us to bring in live air traffic to our synthetic environment in order to visualize the traffic as well as have our simulated entities respond to the live traffic.  This is just one example of how MÄK’s open toolkits allow for the products to be extended  and customized  for creating mission focused solutions.

Len’s Take on our CEO Transition

As the news of Warren’s upcoming departure from MÄK has spread after today’s announcement, I’ve heard from a few long-time partners and customers asking for my take on what this means for MÄK. So I wanted to share a few quick thoughts. But first, this is good time to express how lucky I feel that I’ve had the opportunity to work for Warren for more than 18 years.

I first met Warren when I was 20 years old, when he conducted an on-campus interview at MIT. As I walked past all of the other companies’ representatives wearing suits and ties, there was Warren wearing sneakers, jeans, and a T-shirt (although he did have a blazer on over the T-shirt). I said to myself“That’s the guy I want to work for!” And I have enjoyed doing so ever since. Over the years, I’ve found Warren to be a visionary leader, an eternal optimist, a businessman of unimpeachable character, an outstanding role model, and a good friend. I wish you the best of luck, Warren, in your post-MÄK life, and I thank you for creating and cultivating a company that remains engaging, successful, and fun even after almost two decades.

Tentative Plans for VR-Vantage 1.5

Having released VR-Vantage 1.4 it’s time to move on to the next version. We showed several technology demonstations at IITSEC this year and we are in the process of productizing them for VR-Vanatage 1.5. 

Effects based sensors let users visualize NVG, FLIR and other sensor views without materially classifying data. While these sensor visualizations are not physically accurate, they are pretty good and since they don’t require any changes to models or databases they are super easy to use. They still utilize JRM’s world class technology for sensor visualization, just without the high fidelity physics based stuff (which can be enabled via a drop-in add-on module).

Video streaming is also being added. You can stream simulated video from a VR-Vantage channel to a client application in real time. This is usefull for applications like UAS ground operator stations where the simulated video is streamed from the UAS to the operator station.

IPv6 and the RTI

Earlier this week MÄK released the latest version of the RTI, 4.1. One of the big features of this release was support for IPv6. For those that don’t know much about IPv6, it is the latest version of the Internet Protocol and replaces IPv4. The primary motivating factor behind the creation of IPv6 was the size of the IP address space in IPv4. IPv4 addresses are only 32 bits long. That’s enough for 4,294,967,296 different addresses, but it’s not enough for the size of the internet today.

VR-Forces 4.0.3 with HLA Evolved

Last week, MÄK was pretty excited to release of VR-Forces 4.0.3, which included HLA Evolved support! At this point the complete MÄK Product lineup supports the latest version of the HLA Standard. 

This means that users who want to build federations that take advantage of FOM Modules and other HLA Evolved features will now be able to do it with VR-Forces. FOM Modules is a particularly powerful feature. It allows subgroups of Federates in a larger Federation to share FOM extensions without propagating the FOM extensions to everyone; most federates that don’t use the module can completely ignore it knowing that they will get the information they require in the base FOM, while the subgroup will get information from the base FOM as well as the model.

While FOM Modules and other compelling features are encouraging several major sectors of the HLA market to move to HLA Evolved, many existing federations remain firmly tied to HLA 1.3 or DIS. VR-Forces remains firmly committed to supporting each of these interoperability choices. You can rest assured, whichever simulation interoperability choices you make, MÄK stands behind you.

Simulated Video at AUSA

Ft. Lauderdale in February, AUSA is a great show to attend. This week we are showing how our simulated video technology can be used for stimulating SRI’s real-time video exploitation solution, TerraSight. We’re simulating a UAV flying over the convention center and vehicle traffic in the area.  Using VR-Vantage, we create the sensor view from the UAV and stream that video to TerraSight using MISB standard protocols.  By replicating the exact same data feed that a UAV would produce, integration was seamless. While I was explaining how this system could be used for training, mission rehearsal, or experimentation to a customer, they kept looking in the sky for the UAV. It wasn’t until I unattached the eye point from the UAV and flew around a bit that they were convinced it was a simulation.

VR-Forces 3.12.x Maintenance Period Extended

I am pleased to announce the extension of the VR-Forces 3.12.x maintenance period to December 31st, 2012. While we have seen many customers quickly migrating to the VR-Forces 4.x platform, MÄK understands there are still many other customers who face complex schedules and tight budgets who have not been able to upgrade their VR-Forces 3.x based products yet. As a customer focused company, it’s MÄK’s goal to be as responsive as possible to customer needs. We believe this extension will provide the time needed for many customers to upgrade while still supporting existing systems. 

Of course, MÄK is also committed to helping our customers understand the upgrade process. VR-Forces 4.x has a completely improved and redesigned front end, so we understand the upgrade process can be intimidating. MÄK is currently helping customers understand and work through the challenges faced by an upgrade - we want to help you too. While we are helping customers through the normal support channels (This email address is being protected from spambots. You need JavaScript enabled to view it.), we are also proactively helping through private customer-focused webinars and customer visits. If you are interested in working with us through any of these processes, please don’t hesitate to contact your sales representative (This email address is being protected from spambots. You need JavaScript enabled to view it.).  

As always, the content of our releases and maintenance windows are highly influenced by your needs and requirements. Please don’t hesitate to let us know any concerns or questions you may have about VR-Forces maintenance issues, or any other issue for that matter. We will use your input to reevaluate the current maintenance window in October 2012 to determine if further extensions are necessary.  We look forward to hearing from you!

Better Aircraft Control Tasks: VR-Forces 4.0.4 Sneak Peak

Today I want to give a sneak peak of a coming VR-Forces feature. When we release VR-Forces 4.0.4 early this summer, users will be able to control aircraft in a new and intuitive way. 

Lots of people use VR-Forces to set up complex scenarios with aircraft. Historically this has been done with routes and waypoints. It means you must plan out your routes or set several waypoints, then build plans for your aircraft to move over the routes or between the waypoints. It’s a logical way to script air scenarios, but for pucksters who move a lot of aircraft around in real time, it’s quite complicated.

ATC Global 2012 in Amsterdam

This week I am exhibiting at ATC Global 2012 in Amsterdam. There are 5000 attendees and 200 exhibitors here focused on Air Traffic Management - more specifically, the next generation Air Traffic Management systems being built in the US and Europe. 

So far, theres been lots of interest in our visualization and simulation interoperability solutions. I’ve seen several booths use Google Maps as an interim visualization tool because they didn’t realize that there is a more flexible option - VR-TheWorld and VR-Vantage. 

High Level Architecture (HLA) is becoming the recognized standard for ATM simulations and I have had several enquiries as to how MÄK can help with simulation interoperability. Customers are relieved when they learn that there are MÄK products, such as VR-Link, that do all of the hard coding work for them.

Plug-in Control: VR-Forces 4.0.4 Sneak Peak

In our effort to continually make the user experience better, I wanted to show a small feature we are adding to VR-Forces 4.0.4  -- due out in June 2012 -- which allows users to choose what plug-ins to load when they start VR-Forces. This is a pretty simple feature that’s best described with a picture:

Visualize Radio Communications in VR-Vantage

The next major release of VR-Vantage (1.5 coming out Q3 2012) will let users visualize radio communications. Users of VR-Vantage Stealth, VR-Vantage PVD and VR-Vantage XR (and eventually VR-Forces and SimMetrics) can tell who’s sending radio messages by their“Squawks”. You’ll also be able to see who they’re communicating with via &ldquoRadio Communication Lines”.

VR-Vantage 1.4.1 Released!

VT MÄK is pleased to announce the release of VR-Vantage 1.4.1. This release marks another milestone in our Open Streaming Terrain story by adding the visualization of streaming vector data.  VR-Vantage applications (like VR-Vantage Stealth or VR-Vantage IG) can now stream in point, linear and areal features from a compliant terrain server using the open standard Web Feature Service (WFS) protocol, and use those features to generate textured 3D geometry on-the-fly at run-time.  VR-Vantage applications can:

  • Generate 3D geometry for buildings, fences, and walls by extruding polygons from geo-specific footprints (linear or areal features), and applying geotypical textures based on feature attributes
  • Place pre-built 3D models representing trees, geospecific buildings, lampposts, etc., into the scene based on the locations and attributes of individual point features ("point feature substitution")
  • Automatically populate forests with trees, or populate roads with telephone poles, fire hydrants, etc., by randomly placing 3D objects within areal features, or along linear features.

Combined with our existing support for streaming elevation and imagery, these new capabilities allow you to very quickly visualize 3D environments that are both global in scale, and visually rich:  Just upload your source data to a compliant streaming terrain server such as MAK’s VR-TheWorld Server, configure your feature-to-geometry mappings using an XML-based“.earth file”, and tell VR-Vantage to connect.

To demonstrate the new capabilities, we’ve collected readily available source data for the Hawaiian island of Oahu, put this data on our VR-TheWorld Online server, and shipped a sample .earth file with VR-Vantage 1.4.1.  Check it out using any VR-Vantage application (Download VR-Vantage FreeViewhere) or watch a video tour of Hawaii here.
