hans,

I had played around with http://www.cosmocows.com/OpenGL/ which gives a 
foreign function interface to wrapper on the opengl dlls under windows.

They have a 'full world window' car game, but under that there is a straight 
binding to a subset of the opengl functions.

I had wanted to learn a little 'raw' opengl so this was perfect for me. It's 
a little fussy due to dll versions etc; on my old win98 it crashes, on one 
of my xp machines it insists on updating the entire world window - but 
generally I can have an 'opengl morph' that open gl renders to and regular 
morphs for controls etc. I had no trouble extending the function coverage to 
support opengl 'picking' etc.

The nice thing is that you can have quite a large area rendering many frames 
/ second with low cpu usage.

I can give you more info if it is interesting for you.

regards,
nicholas
