Inverse Z-buffer and video display system having list-based control mechanism for time-deferred instructing of 3D rendering engine that also responds to supervisory immediate commands |
摘要 |
A graphics system includes triangle-engine for real-time rendering into a displayable frame-buffer of image data derived from vertex-based deferred instructions. The system uses homogeneity values (1/w values) for z-buffer-like occlusion mapping as well as for texture mapping. Depth resolution is enhanced for both occlusion mapping and texture mapping by representing (1/w), (u/w) and (v/w) values in a block-fixed format.
