Abstract
A Z-cache is provided for use in rasterizing computer generated images. The Z-cache allows for caching depth information such that a depth buffer may be implemented in system memory without degradation in performance of a depth routine for determining the visible information in a display. The Z-cache may store and compare pixel depth information. Thus, methods of using a z-cache in a graphics system as well as a graphics system, a processing system and a rasterizer are provided which utilize a Z-cache.
