   PyOpenGL and glVertexPointer
  Ok, quick question(those who can answer will understand what I'm talking about):Can I use pyOpenGL and the glVertexPointer binding, so I can set the vertex pointer to an array containing the geometry only at initializing, and then proceed to dynamically change the geometry data every frame, without having to call glVertexPointer each time? We know we can do it in C, you just set glVertexPointer to the address of a block once and then you can write to that block anytime. But is it possible with Python?
