| 摘 要： | 本文对Catmull纹理映射算法进行了改进。当一个像素被两个以上子曲面片所覆盖时。用Catmull纹理映射算法实现其光亮度计算存在一定的不足。本文对存在的问题作了分析，并进行了相应的改进，使之能正确计算一个像素被多个子曲面片所覆盖时的光亮度，并通过实例验证了算法的正确性。

| Abstract: | This paper is an improvement about the Catmull texture mapping algorithm.When a pixel is covered by more than two subcurved surfaces,there are some problems in calculating the lightness.This paper analyzes the existing problems and presents an advanced algorithm.It can exactly calculate the lightness of a pixel covered by multi-subcurved surfaces,and also validates the accuracy of algorithm by example. |
