[osg-users] Normal bindind

[Robert Osfield]

Hi Julie,

OpenGL doesn't support bind per primitive, there is deprecated OSG pathway
for BIND_PER_PRIMITIVE but it has to emulate the functionality and is very
inefficient.

The closest you can get to what you are after is to BIND_PER_VERTEX and
then use flat shading.

Robert.
