Under this Phase I SBIR proposal entitled, "Parametric Generation of Underground Structures for Virtual and Constructive Simulation", TerraSim, Inc. will develop the design for a novel and robust underground structures generation capability that will support correlated virtual, constructive, and game engine simulation systems. This capability will be integrated as a plugin component to our commercial off the shelf (COTS) product, TerraTools(R), which provides the overall geospatial context for underground structure generation. A standalone software library will also be designed. We will create a functional prototype for a 3D underground structure generation system that spans both civil infrastructure and military use. The complexity of underground structures as well as their importance in training, modeling and simulation, and weapons delivery is high. Particular attention will be paid to ease of use and extensibility by using proven parametric urban modeling techniques combined with procedural generation of the underlying geometry and appearance to support virtual simulations. The development of constructive simulation representations for underground structures for OneSAF will address the automatic generation of ultra high resolution buildings (UHRB's) with underground tunnels and connectors, as well as other underground representations supported in the OneSAF Terrain Format (OTF).
