An interactive graphics display architecture

A technique for redesigning a display controller within a traditional graphics display system is outlined. By performing complicated computations within the display controller, the system may be optimized for the needs of a virtual reality display system. Wide angle viewing lens effects and response to user head rotations may be compensated for within the display controller, avoiding the rendering bottleneck. The architecture allows image overlaying to provide more realistic scenes and a mechanism for focusing the time of the rendering engine on sections of the scene which change the most frequently.<<ETX>>
