Hey,
Sorry for what might be a noob question, but is there a way of uniformly subdividing a tetrahedron mesh (just like the Subdivide SOP for polygons)?
I have a tetmesh which i generated from a character (it has the same number of points as the original character so i can drive it with the original deformation of the character). I use a base/deformed tetmesh pair to deform stuff inside the character's volume, but i'd like to subdivide both the base and the deformed tets to have a higher resolution (similar to subdividing a regular mesh after deformation).
cheers

Yeah but I'm not looking for adding more points on just the _surface_, but subdividing each existing tetrahedron into 4 smaller ones (if you know what i mean) – i don't think this method would do that, right? I'll definitely try and explore this direction more, though (i.e. refining an existing tetmesh).
My other problem was (at least in H15.5) if i tried to add extra points in the 2nd input of tetrahedralize, it didn't work if the points were laying on the original surface (e.g. scattered points).
