High Speed Representation of Complex Scenes

Simulation is used to safely test BMDS components and strategies in a controlled environment. FLITES uses physics-based modeling to accurately simulate hardbody and plume radiation. Currently, the processing resources required by this model limit the scene detail of the surrounding environment, which reduces the overall simulation quality. We propose to employ modern image generator technology to generate background scenes for FLITES. This rendering layer will interface cleanly to FLITES through an API. The background rendering layer will run as a distributed thread on a dedicated COTS processor so it will not impact the missile simulation performance, and be cleanly composited with the FLITES generated missile scene using techniques such as GPU shaders. The background scene generated by this new process will use physics-based rendering and atmospheric modeling, and a thermal solver will be used in conjunction with material and geometry databases to produce high fidelity background scenes in real time. A world wide database will be supported, with a location based paging mechanism to balance the system and scene load. Dynamic phenomena such as dynamic sea states and moving clouds will be added to obtain a realistic portrayal of the background scene.
