AVCATT Compact Terrain Database (CTDB) Plug-in

GameSim created a new SE Core DVED plug-in to produce CTDBs tailored for the AVCATT program.

By using the DVED SEE API and libctdb library, GameSim engineers completed the software in less than 3 months. Since its release, the plugin has required minimal maintenance.

LVCIA HITS OpenSceneGraph (OSG) Plug-In

GameSim developed a new SE Core DVED plug-in to produce OpenSceneGraph databases compliant with the LVCIA HITS program’s S2Focus based viewer.

Capabilities included• Pageable OSG database• Transparent buildings

for HITS

On-Demand Dune Geometry Integration

GameSim enhanced the SEE API with a feature that provides on-demand dune integration.

This capability allows OneSAF to process dense dune areas while not impacting visual system performance.

All dune integration is done as a post process during output plug-in execution and provided seamless as scenegraph polygons to those plug-ins that require them.

DVED Vector Data ThinningGameSim provided TerraVista with a new culture compiler that thins vector data.

Thinning dramatically reduces scenegraph polygon counts, as shown in the screenshots.

The vector data thinning plug-in has become an essential part of all production database builds.

DVED Vector Data ClippingDue to implementation deficiencies, GameSim replaced TerraVista’s built-in vector clipping algorithm.

GameSim’s clipping implementation is available as a SEE API method and is used by all production SEE API plug-ins that need clipped vector data.

Other DVED Contributions• On Demand Feature Integration (ODFI)

– GameSim assisted the DVED ODFI team with performance enhancement and memory management by isolating memory leaks and suggesting more efficient algorithms.

• Virtual Battlespace 2 Output Compiler– A GameSim engineer joined the VBS2 project team to help correct VBS2

plug-in performance and memory issues. Within 2 weeks, modifications suggested by our engineer directly lead to a dramatic decrease in plug-in execution time.

• JIEDDO Building Enhancements and Performance Analysis– GameSim investigated the impact of high-detail building visual model

generation on runtime performance and database generation.– GameSim performed an analysis of the CER scene graph to determine

how modifications to scenegraph polygon clustering algorithms would impact EPX-50 performance.

Raydon BARE Database Plug-inAs a separately funded effort, Raydon contracted GameSim to build an SE Core DVED Plug-in to produce BARE format databases.

GameSim produced a full BARE plug-in from scratch that utilized the SEE API with full seasonality support, as shown to the right. The plug-in can produce both summer and winter databases during a single execution.
