Definition
Mesh modeling is the process of constructing a polygonal mesh from scratch by basic operations or editing an existing mesh for a desired geometric shape. Mesh processing includes various operations which modify input mesh for specific purpose, which usually preserve overall shape or local details.
There are various methods to represent a 3D surface, such as NUBRS and implicit surface. Among these methods, polygonal mesh is a very popular one for game industry, for it is simple, flexible, and efficient. We introduce the modeling and processing of polygonal mesh, or, for short, mesh.
A mesh is composed of some basic elements: vertices (red dots), edges (black lines), and faces (light blue areas). Each vertex stands for a specific position in a 3D space, each edge connects two vertices, and each face is a surface patch bounded by a loop of edges. Theoretically, a face is bounded by any number of edges, but triangular and...
