Mesh generation
(重定向自Grid generation)
Mesh generation is the practice of generating a polygonal or polyhedral mesh that approximates a geometric domain. The term "grid generation" is often used interchangeably. Typical uses are for rendering to a computer screen or for physical simulation such as finite element analysis or computational fluid dynamics. The input model form can vary greatly but common sources are CAD, NURBS, B-rep, STL (file format) or a point cloud. The field is highly interdisciplinary, with contributions found in mathematics, computer science, and engineering.
