摘    要:针对八叉树这一布局基础数据结构,设计了一套基于八叉树的三维干涉检验系统,该系统通过对AutoCAD软件产生的图形交换信息(IGES文件)进行实体信息读取,产生布局实体的几何信息,并将之转换为八叉树数据结构,利用八叉树描述空间几何形体的方法,对布局方案中的几何形体进行了三维干涉检验。此系统可以对AutoCAD产生的任意形状的布局实体进行静态和动态的干涉检验。

关 键 词:三维布局  干涉检验  初始图形交换文件  八叉树  AutoCAD

Abstract:It view of octreed laying out basic data structure, a set of 3D interference inspection system based on octree was designed. By means of carrying out the reading of entity information from document of graphics exchanging information(IGES document) produced by AutoCAD software, this system produces geometric information of laying out entity and changes it into an octree data structure. By applying the method of describing spatial geometric body with octree, a 3D interference inspection was conducted upon the geometric body in the laying out scheme. This system could carry on static and dynamic interference inspection upon arbitrary formed entity of laying out produced by AutoCAD.
Keywords:3D layout  Interference detection  IGES(Initial Graphics Exchange Specification)  Octree
