Check out the most recent mail to this mailing list by Bert Freudenberg, were he explains the inner workings of the Ballon3D plugin, to achieve what you propose. The other means would be to change the VM, and bypass completely the bitmapped "Display", and provide Events+a windowed OpenGL context ,to were we can draw within the image. Check out recent emails from myself in the list,the thread titled "decoupling the vm: UI and interpretation". Fernando On Tue, Jan 24, 2012 at 3:04 AM, Lawson English <lenglish5@cox.net> wrote:

Kool. So how could I make the entire World a drawing surface so that I could use the OpenGL drawing throughout the entire squeak/pharo OS window, instead of within another window?

Could a 2D/3D mashup like I have in this video be accomplished? The fps is too slow to be useable for most things, at this point: http://www.youtube.com/watch?v=nSLZKIXeXR4

Is there a way to directly draw to the system window using OpenGL so that intermediate software blitting is eliminated?

The opengl context is already drawing directly to the screen (or rather, to the back buffer managed by opengl). There is no intermediate software blitting involved AFAIK.
