【摘要】 基于八叉树数据结构,开发出了一种新的自适应网格剖分算法。通过设定一些剖分停止条件产生非平衡树,处理PLY文件模型得到简单非均匀正方体网格,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。借用vtk软件系统完成了网格图形的显示,并与图形原始文件进行对比,程序能较好地表示图形形状轮廓。更多还原

【Abstract】 Based on octree data structure, an algorithm for adaptive subdivision of finite difference meshes is developed. In this method, the non-equilibrium tree is generated by setting some cut-off condition, and the simple non-uniform cube mesh is obtained by processing the PLY model, so that the complex shape part of the complex model can be modeled deeply. With the help of the vtk software system to complete the grid graphics display, and comparing with the original file, the program can produce a good representation of the graphical shape.更多还原
