摘要： 作为纹理映射技术应用于规则和不规则曲面的3种算法,即球面整体纹理映射算法、球面局部纹理映射算法以及投影映射算法在纹理映射的研究中具有重要的意义。该文通过两种球面纹理映射算法进行比较,从球面纹理不变形准则出发,分析了这两种算法的优缺点,并且采用基于调和映射的方法,实现了可应用于不规则曲面映射的投影映射方法。

Abstract: Applying to regular and irregular surfaces,these three algorithms have played an important role in the research of texture mapping. Through comparing these two algorithms of sphere texture mapping,this paper analyses their advantages and disadvantages according to the non-distortion criteria of sphere texture mapping. Furthermore,the paper also achieves the algorithm of projection mapping applicable to irregular surface based on harmonic mapping.
