中文摘要：
三维物体的几何造型中，物体通常用三角形网格来描述．随着计算机建模、仿真，虚拟现实与可视化技术的发展，经常会遇到带有纹理的三角形网格模型的简化问题．为此，提出一种带纹理的三角形网格模型简化算法。该算法中综合考虑了模型几何信息以及纹理信息的全局误差，并通过记录每步边折叠操作来消除累计误差，最终生成在形状和纹理上与原始模型最相似的简化模型．
英文摘要：
In computer graphics, objects are often represented by triangle meshes. With development of computer modeling, simulation, visualization and virtual reality technology, the issue of simplifying the triangle mesh model with texture would be often encountered. An algorithm for simplification of triangle mesh model with texture is introduced in the paper. The paper proposes a novel metric to incorporate the geometric information and surface texture information of 3D models. Furthermore, the accumulative error can be eliminated by recording steps of edge collapse. As a result, the algorithm can be applied to generate simplified models, closest to the original in shape and texture.
