有真实感图形的纹理映射算法

THE TEXTURE MAPPING ALGORITHMS

本文讨论了计算机生成真实感图形的纹理映射技术，根据模拟现实物体的表面细节特征提出了三种纹理映射方法。给出了基于双三次Ｂ样条参数曲线面的表面纹理映射算法，和通过表面法向量扰动产生凹凸不平视觉效果的凸包纹理映射算法，并给出了立体纹理映射的实现方法。

The texture mapping in Computer Graphics have been discussed in the paper. Based on the surface texture characteristics of real objects, three mapping methods are given in the paper. Surface texture mapping algorithm based B-splint parameter surface, and bump mapping algorithm based surface voter twist to produce real objects sense are suggested. Solid mapping method is also introduced in the paper.
