A triangle mesh created by contouring an implicit surface
In computer graphics, a triangle mesh is a type of polygon mesh. It comprises a set of triangles that are connected by their common edges or vertices.
Many graphics software packages and hardware devices can operate more efficiently on triangles that are grouped into meshes than on a similar number of triangles that are presented individually. This is typically because computer graphics do operations on the vertices at the corners of triangles. With individual triangles, the system has to operate on three vertices for every triangle. In a large mesh, there could be eight or more triangles meeting at a single vertex - by processing those vertices just once, it is possible to do a fraction of the work and achieve an identical effect. en.wikipedia.org/wiki/Triangle_mesh
