Yes, I think so.
I agree the simplest thing for a user is to specify normals in the
file for the best control over shading. And I agree that in order to
support the crease angle

Thanks for the info.
I took a look at the code. Adding crease angle support does seem
tricky since I think we would have to create new vertex points on the
fly to accommodate 2 or more different normal vectors at that

I agree that when no normals are specified, the proper behavior for

Please view the two attached vrml files and observe very different shading on
