Representation Data in OpenCascade BRep eryar@163.com 摘要Abstract:现在的显示器大多数是光栅显示器,即可以看做一个像素的矩阵.在光栅显示器上显示的任何图形,实际上都是一些具有一种或多种颜色的集合.数学上精确表示的图形在显示器中只能用逼近的方式显示出来.本文主要对OpenCascade的BRep文件中用来显示曲线和曲面的离散数据结构进行说明. 关键字:OpenCascade, BRep, Polygon, Triangulation,…

Visualize Surface by Delaunay Triangulator eryar@163.com Abstract. Delaunay Triangulation is the core algorithm for mesh generation. By Delaunay Triangulator you can make a general method to visualize geometry surfaces, so does OpenCascade. The paper…

Mesh Algorithm in OpenCascade eryar@163.com Abstract. Rendering a generic surface is a two steps process: first, computing the points that will form the mesh of the surface and then, send this mesh to 3D API. Use the Triangle to triangulate the param…
