[osg-users] VertexAttribDivisor -- should it be part of the VAO state?

[Glenn Waldron]

Robert et al.,

Consider: Should the VertexAttribDivisor be stored in the VAO state?

I'm running into issues where a VertexAttribDivisor (high in the scene
graph) is getting lost when drawing various sets of instanced geometries in
a scene. It happens when a new VAO is bound via glBindVertexArray.

The divisor is really a property of the Array. I am thinking that it should
be set in osg::Array and then applied in
Geometry::drawVertexArraysImplementation.

Hope to hear your thoughts.
