Research And Realization Of Texture Mapping Techniques

Texture mapping technique is used to generate texture details on objects. It plays an important part in rendering realistic pictures and is one of the major research areas of computer graphics. According to the regions where the texture is defined, texture is generally classified as two-dimensional texture and three-dimensional texture. 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. 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. OpenGL is also introduced in this paper and some realization examples of texture mapping based on OpenGL are presented in some chapters.
