METHOD AND APPARATUS FOR GENERATING TEXTURED GRAPHICS PRIMITIVES IN FRAME BUFFER COMPUTER GRAPHICS SYSTEMS |
摘要 |
<p>Methods and apparatus for texture mapping graphics primitives in a graphics pipeline architecture system. The methods and apparatus disclosed herein utilize rectangular box filters to down-sample original texture maps thereby optimizing aliasing and blurring when graphics primitives have a two-dimensional texture mapped to a three-dimensional object. The methods of texture mapping graphics primitives in a frame buffer graphics system comprise the steps of determining an original texture map of two dimensions for a surface, storing the original texture map in the frame buffer, sampling the original texture map independently using an asymmetrical filter to construct multiple versions of a texture and to address textured pixels on a display in the frame buffer graphics systems, mapping the textured pixels to areas on the frame buffer, and displaying the textured graphics primitives on the display. <IMAGE></p> |
