ABSTRACT:
The invention reveals faster techniques for scan conversion, slope calculations, and z-buffer and frame-buffer access in the rasterization process of a computer graphics system. This is accomplished by optimizing the method and apparatus to exploit the small size of triangles in applications, and also by taking into account the response of the human visual system to color and depth. Additionally, depth and color information in the z-buffer and image buffer are prefetched into cache memory, thus eliminating the bottleneck associated with accessing these buffers.
