摘　　要：依据两步映射法（ｔｗｏ－ｐａｒｔｍａｐｐｉｎｇ）和体纹理（ｓｏｌｉｄｔｅｘｔｕｒｅ）的思想，将曲面纹理的映射过程分为非实时映射和实时查询两个部分，提出一种能实时显示曲面纹理的方法及相应的抗混叠措施．最后，结合一种快速浓淡算法，为曲面纹理叠加光照效果。This paper describes a new algorithm for real time texture mapping for curved surfaces and corresponding antialiasing methods. Considering the real time property, we divide the mapping process into two part. First, the original texture is mapped onto the complex curved surfaces and creat a texture map off line. Second, the color of each pixel is read from the map through inverse transformation in real time. By combining with a fast shading algorithm, images of objects having pattened shiny surfaces are generated.
