| 摘 要： | 基于八叉树数据结构,开发了一种自适应网格剖分算法。该算法以STL文件模型为根节点进行空间分割,通过递归计算并设定剖分停止临界条件产生非平衡树,从而能对复杂模型的复杂形状部位进行自适应的深度剖分。开发出的相应程序对几何模型文件进行计算和数据分析,最终能够产生质量较高的八叉树非均匀网格。

| Abstract: | Based on octree data structure,an algorithm for adaptive subdivision of finite differential meshes was developed.The algorithm uses the STL file model as the root node for spatial segmentation,and generates an unbalanced tree by recursively calculating and setting critical stop condition,so complex shape parts of complex models can be divided adaptively.The corresponding program was developed to calculate and analyze the geometric model file,and finally proved it could produce a high quality octree non-uniform grid. |
