摘　　要：三维CAD在虚拟环境中有着广泛的应用,其模型数据由于具有复杂的结构且拥有较多的冗余信息而不能高效的运用到虚拟环境的构建中。基于此,针对虚拟场景渲染对数据模型的要求,给出了三维CAD模型数据优化及重组方法,该方法能去除冗余信息,优化文件结构,丰富数据内容,且能够有效地提高虚拟环境的绘制效率。3D CAD was applied widely in virtual environment. The model of 3D CAD has complicated structure and lots of redundant information, so it can＇t be applied to construction of virtual environment efficiently. Aiming at the requiting of data model in virtual scene, this paper brings forward a kind of optimizing and recomposing method of 3 D CAD model. This method wipes up the redundant information, predigests files structure and enriches data content. It can improve the performance of virtual environment greatly.
