So.. more than one person has suggested I come and talk over here on the video I posted.

Really, all I've done so far is write some temporary wrapper code for all the glBegin/glEnd stuff, and remove/replace stuff that was never going to work well (eg. glDrawPixels).

At the moment, I'm playing with trying to improve frame rate.. I'm gradually coming to the conclusion that the GL_IMG_vertex_program extensions is utterly broken in GLES 1.1 on the N900.. which is a shame, as I'd have liked to have used vertex programs for some colouring that's currently being done in software. Mesh animation lerping could have been done with a vertex program too..

I think the best I can do to improve GLES performance is convert as much 3d stuff to use VBOs as possible, and look at GL_OES_draw_texture for 2d stuff (which is really slow atm).
