LNK Corporation, Inc., in conjunction with JRM Enterprises, Inc. and MultiGen,proposes to develop a wavelet compression library which will be able to supportOpen GL and Direct 3D rendering on commercially available low cost PC boards.This library will extend LNK's existing wavelet compression algorithms, whichhave been used to compress hyperspectral sensor data, digital elevation models,and image files which may be used as texture maps. The library will also supportmaterial based classification and region of interest definition, used in sensorsimulation. While lossless compression of 2:1 can be readily achieved, the LNKTeam will explore hardware-specific optimization and scene fidelity tradeoffsthat permit order-of-magnitude improvements in compression ratio, enablingmultiresolution mip-mapped terrain databases to be rendered at frame ratesappropriate to tactical aircraft simulation. In Phase I, LNK will developan experimentation testbed based on a PC platform using commercially availableruntime APIs to explore database paging, system architecture, and software designapproaches, collect metrics on perceived and positional accuracy of rendereddatabases, and identify likely NAVAIR systems and programs for Phase II development,testing, and utilization. The technologies to be developed as part of this effort have very broad commercialapplication, and the availability of real-time graphics and advanced networkingconnectivity in PC and desktop environments creates a wonderful array of newpossibilities for commercial product development, especially in the education andtraining, and commercial gaming markets. The collaboration capabilities to be developedunder this Phase I effort go far beyond currently existing collaborative design and learning tools, and represent the next wave of distributed desktop software environments which take advantage of emerging DoD practices such as the DMSO High Level Architecture. Our product goal is to create software products and services which facilitate both DoD and other desktop customer needs for interactive collaborative environments.
