第一章:曲面表达(Surface Representation) 几何处理(geometry processing)的主要任务是将各种算法应用于几何模型之上。本章主要讨论的是几何模型的表达方式,具有较多抽象的数学讨论,但是较为体系化地阐述了各种曲面表达方式的缘由、优缺点和特性。 1.1 曲面的定义和属性 从高屋建瓴的视角看,一个曲面(surface)的表达有两...
网格划分——Mesh操作 网格划分是ANSYS有限元处理的一个重要步骤,其网格划分质量的好坏直接关系到有限元仿真结构的正确与否,ANSYS自带有网格划分模块,但是也有很多优秀的专业有限元处理软件也可以进行网格划分操作‘,且可以划分出很漂亮的网格,比如Hypermesh等软件,这里我使用ANSYS自带的网格划分功能为大家讲解网格划分基本操...

processing a large number of very simple objects is often much more efficient than processing a smaller number of more complex ones.This is why the somewhat extremal choice of C^0 piecewise linear surface representations, i.e., polygonal meshes, have become the widely established standard in geom...
