OpenGL in external window?

So I had hopes of drawing with OpenGL to the new external windows, but
they were dashed early on.

OpenGL requires a "handle" returned by OpenGL primCreateRenderer: flags
x: y: w: h:

which evokes <primitive: 'primitiveCreateRendererFlags'
module:'B3DAcceleratorPlugin'>

Creating a version the B3DAcceleratorPlugin that can accept some kind of
reference to an external window is beyond me.

It would allow a kool demo video though.

Anyone care to take a stab at it?

Why is having OpenGL in a second window more impressive than having an OpenGL subview in your main window?

I thought your point was to demo the multiple windows.

In this demo, I'd keep the main window as the IDE window and the external as the drawing window.

It would demonstrate how flexible Squeak is that you could (if it is possible) redirect drawing to some other window.

Reading a bit more about supporting multiple windows with OpenGL, what is actually needed is to associate a context with a given window. The B3D code doesn't have the concept of more than one window (not surprising) so I'm guessing that it would be harder than I initially thought.

It would be nice to see pyglet-level support for OpenGL in Squeak http://www.pyglet.org but I'm not capable of contributing much to such a project, I'm afraid.

It would be great to see some serious usage after all this time. Surely there is someone out there that can take up the B3D stuff and make it Do The Right Thing?
