[Bf-committers] Vertex Buffer Object/Vertex Buffer Array

Hi Antony,

you're right about this. But as Ton wrote on the blog some time ago
Blender is about to move to OpenGL 2.1, this would be a great opportunity to
rewrite a great deal of legacy code and get rid of these old structures.

Best regards

Betreff: [Bf-committers] Vertex Buffer Object/Vertex Buffer Array

It has struck me as odd that we have support for vertex arrays AND vertex
buffer objects wrapped in the same code and we still fall back to immediate
OpenGL mode if VBO option is off.

Vertex Arrays are included in OpenGL 1.1 and blender already requires OpenGL
1.4 if I remember correctly. They are also faster than immediate mode. And
apart from that, OpenGL 1.1 has been everywhere since like...forever!

We have to spend so much energy maintaining both front-ends, where
maintaining just one would be much simpler.
