Just wanted to attach my nabble presence to this post, since it seemed anonymous on nabble and not visible on markmail.
I really hope there is a migration path for me from 6.2/OpenGL1. A simple surface rendering of polygon data in an vtkExternalOpenGLRenderWindow became much worse going from 6.2/OpenGL1 to 6.3/OpenGL2 (see the two pictures).
I've spent an embarrassing amount of time on this, when I should be writing, and I'm not sure what to try next.
Many thanks in advance,
Mike
