I'm only after a macro that average normals based on a matrix, like in
ordinary heightfields. The tricky thing is that the faces can be connected
in 2 ways, based on what serves the curvature best.. I don't know the
mathematical names for it.. I call them "quad faces".. Two faces form a
square, but this can happen in 2 ways.. I use both ways and I need a macro
to smooth that matrix.. I think, ordinary heightfields also swap the
quad-faces depending on the curvature..

If your macro can handle this - please ! ...share it. :o)
Or if I didn't make myself clear, I can try again.
