Different realizations using span shading hard­ ware are discussed. Their drawbacks lead to the concept of a triangle shader, designed as an ASIC. Interfaced to a signal processor for geometry computations, this chip will provide an effective and low-cost 3D-extension to graphics subsystems in the PC environment.
