Two-dimensional texture mappings are summarized in this paper including Catmull algorithm and Blinn algorithm, two-step texture mapping, environment mapping and bump mapping. Moreover, a new method of regional texture mapping based on intermediate surface is presented and a new algorithm is promoted to reduce texture distortion in the process of mapping onto the sphere surface.

For regular topology surface, intermediate surface local texture mapping are used; for irregular topology surface, subdivision surface local texture mapping are used. So different topology surface using different texture mapping methods can solve the contradiction between texture effect and processing speed when they are dealt with by single method. The three judge conditions of texture distortion in the process of mapping onto the sphere surface are discussed and the exiting algorithms of mapping are analyzed, the new algorithms of mapping onto the sphere surface are presented. In order to enhance the realistic of graphics, a new function of wood texture is presented. OpenGL is also introduced in this papers and some realization examples of texture mapping based on OpenGL under the environment of VC++ and POV-RAY are presented in some chapters.
