| 摘 要： | 针对三角面片表示的零件模型，通过对三角面片信息进行处理，提出一种通用的数据预处理方法，可以对三维模型进行拓扑重建，实现模型的体素分离，提取三维模型的几何特征。利用这一方法，可以实现VR系统与通用的CAD系统之间实现信息交换，让不同系统的产品数据得到顺畅传递，同时为后续的虚拟装配及机构运动仿真提供必要的信息基础。

| Abstract: | For part model presented by triangular patches,through processing the triangular facets of information,a common data preprocessing method is given.The topology of three-dimensional model can be rebuilt,and the voxel is separated by extraction of three-dimensional model geometry.Using this method,VR systems can exchange information with common CAD systems,and product data from different systems can be delivered smoothly,while the follow-up of virtual assembly and body motion simulation can be provided with t... |
