geometric data model

基本解释

Using the tree method partitions the unordered point data, so the geometric model of the scattered data is generated.
并通过树形的空间结构完成对密集散乱点群空间分割，由此实现对散乱点群数据的几何分割。
It adopts an object-oriented data structure to describe both the geometric model and geometric constraints of a product in a uniform way.
该系统采用一面向对象的数据模型统一表示几何元素与几何约束；
This paper took discal cam as an example to bring forward a method of using computer program to get 3D geometric data of planar part and make its model in reverse.
以盘形凸轮为例，提出一种用计算机编程实现平面零件实物三维几何数据获取以及模型反求的方法。
