     摘要: Abstract. Triangle is a 2D quality mesh generator and Delaunay triangulator. Triangle was created as part of the Quake project in the school of Computer Science at Carnegie Mellon University by Jonathan R. Shewchuk. Triangle is a small C program and its Delaunay refinement algorithm for quality mesh generation is a hybrid one. It includes divide-and-conquer and incremental insertion algorithms and sweepline Delaunay triangulation algorithm. This paper is focused on the usage of the Triangle and   阅读全文

     摘要: Abstract. MeshVS means Mesh Visualization Service. It can be used to representation mesh in different style, such as colored stress patterns mesh, mesh with text and mesh like vector(with arrow). So MeshVS usually used for CAE programming. This paper focus on the MeshVS usage.

     摘要: Abstract. BRep is short for Boundary Representation. Boundary Representation gives a complete description of an object by associating topological and geometric information for solid modeling. In this case, objects are described by their boundaries. There are two types of information in BRep: Topological information and Geometric information. This paper is concerned with the Cone BRep in OpenCascade, and also show how to use Tcl script to dump cone BRep info.

     摘要: Abstract. This paper is concerned with parametric curves and surfaces definitions, such as singular point and regular point and their application in OpenCascade. The two most common methods of representing curves and surfaces in geometric modeling are implicit equations and parametric functions. Successful geometric modeling is done using both techniques. When you use parametric functions to represent curves and surfaces, you need to pay attention for the characteristic of it, such as singularit  阅读全文
