Could you please be more specific about the problems you noticed?
I just look at one of your last changes, which removes unneeded
references. AFAIK, this was intentional, because what I really want
to modify is the "n" NDArray (which is assigned to vertexnormals in
the end). By removing the references, "n" is never updated.
