Strangely enough, when I used the bool CGAL::Polygon_mesh_processing::does_self_intersect function, it indicated that this mesh does not self-intersect, which is contrary to what I expected based on my visual inspection of the mesh. Here are the coordinates of the vertices for reference: ...

网格划分——Mesh操作 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...
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)的表达有两种方式:参数化表达和隐式表达。参数化表达...

PCA、LDA都不能处理这个非线性的降维问题。但由于这是个流形,如果能将该曲面以某种方式展开成为平面,那么就完成了从3维到2维的降维。后面就可以用上述MDS的方式继续做降维。 至此,该问题转化...”可以再被弯曲回一张平面,即从三维到二维。为什么呢?因为“被弯曲了的平面”其实是2维信息以某一形态放入了3维,在...

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...
