Interface between Image Generator and Display

Many existing image generator (IG) systems lack the required fidelity for particular tasks because the tradeoff of rendering performance vs. image update rate causes scene load management to limit, or cull, certain objects form the scene. Several methodsare used, including dynamically limiting the back of the viewing frustum (range limiting), dropping moving objects, or forcing the level of detail of selected objects to a lower level of detail in times of heavy load. Allowing the IG more time to rendereach frame of imagery would provide a mechanism for those systems to include additional scene content into each rendered image. A system which can manipulate raster imagery from a video source, to provide smooth motion on display refresh intervals based onownship motion, would allow the IG the extra time it desires to improve scene content. The Intermediate Frame Calculator (IFC) system proposed herein would provide such a solution, improving the performance of both existing and new IG systems. The proposed system development has commercial benefits both in and out of the field of simulation. In simulation, the system can be directly applied to both new, low cost IG developments, as well as allowing enhancement of existing systems, with minimalsystem impact. The programmable logic based digital signal processing platform has application to other real-time signal processing applications such as acoustic (including SONAR), RADAR, or other complex data. RPA already sells prgrammable logic basedsolutions into these arenas. The addition of this platform would provide a new level of performance not currently available in those systems.
