Examples of TriangleMesh

artofillusion.object.TriangleMesh
The TriangleMesh class represents an aritrary surface defined by a mesh of triangular faces. Depending on the selected smoothing method, the surface may simply consist of the triangular faces, or it may be a smooth subdivision surface which either interpolates or approximates the vertices of the control mesh.
toxi.geom.mesh.TriangleMesh
An extensible class to dynamically build, manipulate & export triangle meshes. Meshes are built face by face. This implementation automatically re-uses existing vertices and can generate smooth vertex normals. Vertice and face lists are directly accessible for speed & convenience.
