bool OpenTissue::t4mesh::mel_write	(	std::string const &	filename,
		t4mesh_type const &	mesh,
		point_container &	points,
		real_type2	scale
	)			[inline]

MEL Write Routine. This function is great for exporting a visual representation of a tetrahedra mesh into a MEL (Maya Embedded Language) file. A MEL file is a script file that can be run in Maya. The output file will thus create polygonal meshes corresponding to the individual tetrahedrons in the tetrahedron mesh.

Parameters:

	filename	The filename to write to.
	mesh	The tetrahedra mesh that should be written
	points	The coordinates of the nodes of the tetrahedra mesh.
	scale	The individual scaling to be used upon each tetrahedron.

Returns:

If succesfully written to the specified file then the return value is true otherwise it is false.

t4mesh_mesh_lofter.

• uses tetgen to loft/extrude a closed two-manifold polymesh to a generic tetrahedal mesh

Parameters:

	polymesh	A poly mesh, which holds a closed two-manifold.
	t4mesh	A generic t4mesh, which upon return holds the generated tetrahedal mesh.
