Detailed Description

Marching tet iso surface algorithm with filtering to remove unnecessary topology.

Three levels of filtering are possible:

none: Don't filter; the full intersection between the iso surface and the tetrahedral decomposition of the mesh is generated
partial: Remove points from vertex to cell-centre edges and merge triangles that form a contiguous cut through a single cell
full: As partial, but also remove points from face-diagonals and merge edges that originate from the same face
clean: As full, but also remove faces that were made non-manifold by the point filtering process. Note that this process is not entirely robust. The removal process can result in entire contiguous sections of the surface being removed. If small imperfections in the surface can be tolerated, then it is advised to use "full" filtering instead.
