NPSGDL: An Object Oriented Graphics Description Language for Virtual World Application Support

Many virtual world applications today represent the cutting edge in real-time 3D interactive graphics. Virtual world applications must model many complex, often changing, graphical objects. These graphical objects must be modeled both visually and behaviorly. The performance of most applications of this nature is determined by the graphics processing capabilities of the hardware used. An efficient, application independent method for describing and managing graphical objects is essential for rapid prototyping and development of robust virtual world applications. This thesis presents an efficient, flexible and extensible graphics description system, NPSGDL, used in virtual world development at the Naval Postgraduate School.
