| 摘 要： | 文章分析了多边形模型简化过程中纹理扭曲的产生原因,指出纹理扭曲是由于简化导致模型表面几何方向变化和纹理方向变化不一致造成的,并据此提出了一个根据几何和纹理方向变化来度量纹理扭曲的简化算法。该算法可以有效防止简化模型上纹理扭曲的发生,自动快速生成在几何和纹理特征上都保持得较好的简化模型。 |

| Abstract: | By the analysis of texture distortion in model simplification,this paper points out that the texture distortion mainly results from the discord of direction variation between texture and geometric space,which is caused by the simplification to the surface.According to this,a new simplification algorithm is presented in this paper.It measures the texture distortion in simplification with the direction variation in texture and geometric space,so the texture distortion can be prevented efficiently and the simplified models can be produced with texture and geometric features preserved well. |
