曲面纹理映射算法研究及实现

Research and Implementation on Surface Texture Mapping Algorithm

从纹理映射的基本算法出发,对传统的纹理映射算法进行分析,针对其中复杂曲面和不规则多边形难以直接应用的问题,对参数曲面纹理映射算法进行研究。选择双三次Bezier曲面和NURBS曲面逼近自由曲面,将纹理通过某种方式映射到曲面上实现参数化,结合两步纹理映射技术,实现参数曲面和不规则曲面的纹理映射,研究内容对于纹理映射的应用具有重要意义,值得进一步研究。

Based on basic algorithm of texture mapping,analyzing the traditional texture mapping algorithm.Aiming at the problem that irregular polygons and complex parametric surfaces in the texture mapping algorithm are difficult to apply,the surface texture mapping algorithm is studied.The bicubic Bezier surface and NURBS surface are selected to approximate the free surface,and the texture is mapped to the sur face in a certain way to implement parameterization.In combination with the two-step texture mapping technology,the texture mapping of parametric and irregular surfaces is implemented.Its application is of great significance and deserves further research.
