摘要
文中运用两步映射原理解决了曲面的参数化问题,改进了一种采用面积比不变性约束的球冠映射算法,消除了采用传统的整球面和半球面参数化方法向中间曲面作映射所带来的纹理变形问题,进而较好地实现了由非参数化面片拼接成的曲面表面的纹理映射。
An algorithm based on the invariability, of ratio of areas is improved on the parametrization of the surface, which uses the twopart texture mapping. This method eliminates the distortion in the process of the mapping on the intermediate surface by the traditional sphere and heruisphere parametrization. As a result, this method realized the surface＇s texture mapping,which is constructed by the nonparametic patches.
