So there is no way to direct access the surface buffer (I mean get a byte/int array that is the "actual" memory part that opengl can draw too)?

I was wondering if it is possible to do just like you do with a bufferedimage that can expose a WritableBuffer (through getRaster).

Is there other ways to perform direct access othen than on a texture? And is it possible to have OpenGl draw on a surface (on video memory or system ram?).
