摘　　要：讨论了三维纹理映射技术中的过程纹理,分析了几种常用的过程纹理函数,运用线性插值和二次插值方法对传统的木纹函数进行了改进,保证木纹颜色变化的连续性,并给出了基于OpenGL实现颜色线性插值和二次插值的木纹效果实例.Process texture of three-dimensional texture mapping techniques is summarized including several procedural texture functions. Traditional wood texture function is modified by linearity interpolating and quadric interpolating, which make the change of wood texture continuous. Wood texture realization examples based on OpenGL by linearity interpolating and quadric interpolating are also presented.
