Detailed Description

Representation of a two-dimensional triangular mesh.

Triangular meshes are represented by a hierarchy of geometric objects: vertices are at the lowest level, edges consist of vertices and triangles consist of edges. Functions like getvertices_tri2d are provided to skip levels of the hierarchy in order to obtain the vertices or edges of a tetrahedron.
