METHOD OF REMOVING INDEX OF GEOMETRIC PRIMITIVE, RASTERIZATION DEVICE, COMPUTER READABLE MEDIUM

摘要

PROBLEM TO BE SOLVED: To solve the problem that a large amount of data such as vertex data has to be processed for plotting a geometric primitive. SOLUTION: A pixel shader carries out first texture look up within an index buffer, and operates so as to obtain a vertex index value of a geometric primitive to be displayed. The pixel shader further carries out second texture look up within a vertex buffer, and operates so as to obtain vertex data corresponding to the vertex index value already obtained about the geometric primitive to be displayed. The first and second texture look up is carried out repeatedly by the pixel shader so as to obtain the vertex data about each vertex required for regulating the geometric primitive to be displayed. Then, the pixel shader operates so as to carry out rasterization of the geometric primitive to be displayed using the already obtained vertex data. COPYRIGHT: (C)2006,JPO&NCIPI
