Abstract

A method and apparatus for processing primitives in a computer graphics display system. The apparatus comprises a graphics device which receives commands and data from a host computer of the computer graphics display system. The data includes clip coordinates which are perspective projected by the graphics device into window coordinates. The host computer of the computer graphics display system is programmed to execute a geometry processing pipeline which transforms object coordinates associated with a primitive into clip coordinates which are then delivered to the graphics device. The graphics device then performs perspective projection on the clip coordinates to transform the clip coordinates into window coordinates.
