Antialiasing in two - dimensional texture mappings is also discussed including a modified summed - area table algorithm . three - dimensional texture mappings are summarized including several procedural texture functions and fourier synthesis techniques 在三维纹理方面，重点分析了几种常用的过程纹理函数与fourier纹理合成技术，并对传统的木纹函数进行了改进。
