-* `setMeshEdge` defines a mesh edge between two vertices and returns an edge ID.
-* `setMeshTriangle` defines a mesh triangle by three edges.
-* `setMeshQuad` defines a planar mesh quad by four edges, which is internally triangulated. Prefer to define triangles if you can.
-* `setMeshTetrahredron` defines a mesh tetrahedron by four vertices.
