High Speed Representation of Complex Scenes

Leveraging Phase I design and proof-of-concept demonstration software, JRM proposes to develop Phase II prototype simulation software called OSCRE ("On-the-fly Scene Construction and Rendering Engine") to provide FLITES support for large-area, complex backgrounds. This Phase II prototype for FLITES will allow rendering highly complex, large area urban and littoral scene databases directly from GIS datasources at HWIL frame-rates, with support for on-the-fly (OTF) material classification and credible, physics-based signature synthesis and sampling. First, JRM will implement additional advanced OTF data processing and scenario definition techniques, to support loading and materially-classifying large amounts of raw terrain data, while synchronizing the trajectories of 3D vehicles and FLITES targets within user-defined scenarios. Second, JRM will implement additional advanced OTF GPU-based signature synthesis and rendering techniques, to carefully address all the signature requirements for MDA, including appropriate spectral synthesis, Nyquist-oversampling, and directional effects (e.g. Sandford-Robertson-based solar glint and thermal emission). Third, JRM will implement a flexible, fast, and comprehensive interface between OSCRE and FLITES to assure correlation during background / target imagery production and synthesis, while retaining phenomenology and sampling. Finally, JRM will perform verification and validation studies of the Phase II prototype against non-real-time government model codes and field data.
