SBIR-STTR Award

The capability to modify terrain in real-time to create realistic modifications will provide training value by assisting in the visualization of the occurrence in the training scenario. For example, the capability to display the creation of craters with explosions or the tracks of vehicles as they move across soft terrain can add a great degree of realism for training. Diamond Visionics has developed the capability to construct and display dynamic terrain using its GenesisRT™ visual system. This capability exploits the design of GenesisRT™ to generate and display in real-time a terrain skin using elevation data rather than fixed polygon models, such as a terrain skins generated in OpenFlght format. The capability to modify terrain need not be limited to the terrain skin itself. For example, modifications to bridges and overpasses in real-time would provide training value as well. DVC has developed software that permits plowing of craters that can be used both for the modeling of plowing and the modification of any object in the same manner.

The objective of this SBIR is to research the latest state of the art computer graphics technology and implement realistic, high-fidelity dynamic terrain in a visual simulation environment to improve the realism of the soldier-machine/terrain interface, thereby improving the reliability of modeling and simulation and enhancing the accuracy of the model''s predictions. Diamond Visionics has achieved the Phase I objective by investigating and implementing various techniques for representing real-time terrain deformation as well as increasing terrain rendering realism. This was accomplished by leveraging GenesisRT, a rendering engine designed to produce the visual scene directly from source data, with no preprocessing required as with traditional systems. In Phase II, Diamond Visionics will focus on refining and expanding upon the technology developed in Phase I and integrating it within a Motion Base Technologies (MBT) ground vehicle simulation system at TARDEC. The goal of this integration will be to generate and render extremely realistic and dynamic synthetic environment, capable of visualizing complex terrain modifications at run-time. With modern engineering vehicles such as the Mine Resistant Ambush Protected (MRAP) family of vehicles there will be a growing need to update terrain representations and allow dynamic interactions in a visually plausible way.
