did you notice that you can save the image in the middle of the animation and it will continue on restart :)
I didn't notice that. However, a there were several things I did notice:
1) you could have more than one GL Morph open at once. However, if you resized one  GL morph window, the drawing area of the other would resize.
Indeed :)
yeah. it looks like i don't switching current GL context when resizing, which affects currently active context.
2) large windows tended to leave a lot of artifacts behind during movement (the video shows this towards the end).
there is two "modes" to blit on Morphic display - one is just copy directly to Display, and another is to separate form and then draw that form as usual. so, these artefact is not related to OpenGL per se, but mainly to how you make rendered results appear integrated in morphic.
3) creating more than one window would sometimes evoke the debugger. Proceeding eventually would create GL morph windows but they might or might not have valid contents. 4) saving occasionally caused errors, but the save continued anyway and restarting the image didn't show any problems.
everything is in your hands :)
I see an awful lot of potential for OpenGL on Squeak/Pharo.
Of course, being involved iwth SiliconSqueak, I hope that we can transcend all current technologies and eventually create something truly different and better.

Is there a way to directly draw to the system window using OpenGL so that intermediate software blitting is eliminated? The integration of 3D and 2D on the squeak desktop (World morph) would be much easier and faster if there weren't so many layers of copying being done, as is the case with my demo video. If there IS a way, can you create a demo of it,, or explain to me how to create a demo of it? Thanks, Lawson
