FAST PERSPECTIVE TEXTURE MAPPING FOR 3-D COMPUTER GRAPHICS

摘要

A method of processing computer graphics information for rendering an image on a display, comprising texture mapping of a pre-prepared texture map to flat surfaces of an object which is to be viewed in perspective on the display, wherein each surface to be texture mapped is scanned along notional lines of constant z (depth) coordinate (z-lines) to determine the end coordinates of those lines, to which the texture values of the pre-prepared texture map can be mapped without modification for perspective.
