VR-Vantage 1.4.1 Released!

Posted by on VR-Vantage

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.

Beyond the new streaming feature capabilities, we’ve also begun to improve our class documentation and examples. Please see the new Tutorials page in our class doc.

Lastly this release also fixes a number of bugs, including:
· Connection pages fixed to provide better out of the box connections to DIS and HLA applications
· Fixed several debug mode crash bugs related to connecting to HLA exercises
· Fixed several Linux crashes related to library mismatch

For a complete description of all changes and improvements please see the Release Notes:
