NPSNET: Physically-Based Modeling Enhancements to an Object File Format

Abstract

The Naval Postgraduate School (NPS) has actively explored the design and implementation of real time three dimensional simulators platforms have had tremendous success due to the fact that a common object format was used. Prototyping time is dramatically reduced when the tedious and often repetitious task of object design is replaced with the simpler task of modifying an existing object description file. The current level of support that the NPS Object File Format (OFF) provides is descriptions for lights, lighting, material characteristics, the expected graphics drawing primitives (lines, polygons, surfaces,...), and provisions for texturing and special lighting effects (spotlights, decaling,...). The objectives of this research are the enhancement of the basic OFF structure with information necessary for accurate physically-based rendering in real-time; to construct a library of functions specifying an object's physical properties and the internal/external forces controlling the object and to develop a tool to rapidly design and test an object's dynamic characteristics.
