| 摘 要： | 在计算机图形学中，三维几何模型通常用多边形网格进行描述．由于网格数据的处理时间和存储代价与多边形的数量成正比，过于复杂和细节化的网格会给图形数据的存储、传输、计算和实时绘制等带来负担．文中综述了国内外几何网格简化及相关技术领域的研究与进展，对相关技术及其特点进行了介绍和分析，给出了网格简化方法的分类，并就该领域未来的研究方向进行了展望。

| Abstract: | In computer graphics, 3D objects are often represented by polygonal meshes. Since rendering or storage cost of object is proportional to the number of polygons in mesh, too complex and detailed model will cause computer system overloaded in storage, transmission, computing and real-time rendering of graphical meshes. Therefore, model decimation techniques are required in computer graphics fields. In this paper, the techniques and latest achievements, at home and abroad, about mesh decimation are detailed and analyzed. The future development in the domain is also discussed. |
