Applications of Shader Technique in Visual System Development Based on Cg

Shader technique based on Cg stands in the foreland of the computer graphics field today,combining with hardware rendering technique of graphic card,which can reduce system burden and get more vivid visual effect through programming vertex and pixel of flow effect of water,such as illumination,HDR,bump maping,and so on.Compared with traditional mipmaping algorithm,the shader technique of multi-resolution texture based on Cg need not get so many textures in order to obtain more smooth mipmaping texture.Finally,the virtual driving simulator is presented as a sample of related solutions and technical applications.
