A New Thread: Aerodromes coming to the MAK ONE Fall 2021 release

In product management, we often look at releases as a tapestry, where each thread represents some set of features that are closely related to others. The threads spend some time at the surface to paint a particular color, and then sometimes disappear in the tapestry only to resurface some later time in a future release. (I've mentioned this analogy...

The MAK ONE Road to Release

Earlier this year, I shared the MAK ONE Tapestry story about how a mature product evolves at MAK. With each release, there are threads of capability that are wrapped up, others that continue on, and others still that are just beginning and will bring new benefits for releases to come. I'd like to update you on where we are today. We've been working...

The Threads that Weave the MAK ONE Tapestry

MAK is quickly approaching that magical time of year — release time! Almost every March for the last ten years, we have released the MAK ONE suite. Usually, I/ITSEC heavily influences our release roadmap; we have a general goal to finalize features to show off at I/ITSEC, and then a full push to go through final testing and bug fixing that culminat...

Tech Tip: Using Entity Control Panels in VR-Forces

VR-Forces has always allowed you to give detailed instructions to entities by issuing tasks, creating plans, or writing custom Lua scripts. These are great tools for defining how you want an entity to behave and then letting it run. But when you need to give simple, immediate commands to an entity to initiate a change in behavior the Entity Control...

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.

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.

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.

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.

Thinking of Linking - Problems with MAK RTI 4.0 on Linux

As many of you may have seen, we just released MAK RTI version 4.0.1. This release fixed two significant problems with MAK RTI version 4.0 on Linux. We recommend all customers who are using version 4.0 move quickly to version 4.0.1 to prevent additional problems. Today I wanted to take a moment and explain in more detail the nature of the problems.

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.

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.

VR-Exchange: Adding Support for Your MATREX Federation

While VR-Exchange has always supported DIS and HLA through the RPR FOM (multiple versions), this year MÄK is making a concerted effort to broaden our support for other commonly used FOMs and protocols.

To this end, we have recently added several new brokers to support FOMs used extensively by the US DoD. We have started with a broker to support the MATREX Federation. We currently support MATREX version 7.x, but will upgrade to version 8.0 when it is released later this year. In the past we have had limited support for MATREX via a FOM Mapper plug-in. While this limited approach worked, we believe it was not very robust. All new translation to the MATREX FOM is done through a new stand-alone broker, offering robust and MATREX-specific translation options. Additionally, we are pleased to announce support for the Joint Land Component Constructive Training Capability (JLCCTC) Multi-Resolution Federation (MRF). We will also begin work on JLCCTC-Entity Resolution Federation (ERF) support in the coming months.

As with all new VR-Exchange FOM support, translation between these and other protocols and object models can be complicated. Depending on what protocols you want to bridge between, the object model may or may not support robust translation capabilities. Additionally,VR-Exchange has not been extended to support all the objects in any of these FOMs. As has been our historical practice, we will continue to expand translation based on the needs of our customers. Let us know what you need and we will be happy to figure out ways to make your exercise successful, in addition to explaining limitations you may face.

A Look into MÄK’s Command Staff Training Approach

Commanders, like all good leaders, are responsible for the people below them. But they can’t do it alone. A commander’s staff exists to support the commander, work as a team, and deliver information to help make good, informed decisions. Training and preparation enable the command staff to function efficiently and properly in challenging situations; training allows the commander and his team to assess the situation, make decisions, and communicate those decisions.

Simulation plays an important role in command staff training; it’s job is to stimulate those situations where learning takes place. The simulation content depends on the echelon (level) and the missions the staff is being trained for. Marine Captains need entity-level simulation to train look-ahead surveillance for convoy protection missions while General Officers need aggregate-level simulation to model wargames for course of action analysis. (And there’s countless more examples of both.)

Modeling all of the elements needed to stimulate a command staff "” all the activity in a training scenario "” is a huge endeavor. Especially when it includes the behavior of opposing forces, the background civilian population, the political and social environment as well as the friendly force operations. To make it happen, commanders either need role players acting out the parts of each unit/entity/vehicle/person or a very powerful, believable, and capable artificial intelligence (AI) solution. Since full scale operations are time consuming and expensive to setup and run, many training tasks use the divide-and-conquer approach of focusing lessons on tasks that are manageable subsets of a complete environment.

Amping Up the Realism of Mixed-Reality Training

A US soldier is trapped under rubble from a damaged building in hostile territory. As a Pararescuer, your team must get in, stabilize the situation, and get out – skins intact.

The rescue mission begins with a helicopter ride over to the site - the ride is bumpy and loud as combat zones dot the geography below. The war worn building comes into view and when you arrive, you fast rope out of the helo and into the rubble. You navigate to the trapped soldier and as you begin to address the situation and tend to the rock pinning him down, there’s an explosion. Even more smoke, debris, and confusion fill the area; when the dust settles, you learn that more soldiers are injured, even a civilian is hurt. 

What do you do? How do you react?
