I don't like about that is when I triangulate a
trimmed NURBS surface with holes in it, the
triangulation is correct but all the normals generated
are in the opposite direction of the NURBS surface.
In my case the BURBS surface has a normal (0,0,1.0)
but the normals generated by the triangulator is
(0,0,-1). If this is consistent, then I can do the
geometryinfo.reverse() to solve this problem. But it
does not happen all the time.
Any suggestions for this problem?
Thank you
