Abstract
A method and apparatus for rendering a real-time synthetic environment on a computer display. A hidden surface removal technique is provided which combines an efficient pixel rendering architecture with a simplified modeling process. Specifically, the computer pixel graphics hardware processing load is balanced against a software geometric load to obtain optimum rendering performance by utilizing a 'full' buffer in combination with adaptations of the z-Buffer and priority-list algorithms.
