摘　　要：提出了一种基于顶点聚类的新简化算法。通过引入二次误差测度求解网格单元的最优代表点,提高了简化质量。分析了文物模型纹理映射的特殊性,提出合适的映射方法,建立了几何模型与纹理图像之间的映射关系,实现了非参数化三维模型的纹理映射,使得模型具有照片真实感。A novel simplification algorithm based on vertex clustering was proposed in this paper. The simplification quality was improved by using Quadrie Error Metrics to compute the placement of each cluster＇s representative vertex. Based on the analysis for the particularity of texture mapping of cultural relic model, the appropriate mapping method was proposed, the mapping relations for geometric model and texture image was established, and the texture mapping of the three-dimensional model eomposed of the non-parameterized surfaces was realized. These processes enable the model photo-rea listie.
