I'm working on my trusty notebook now, but the SiS graphics card is resulting a major pain in the ass:
- warning: OpenGL VBOs not supported
- warning: OpenGL shading language not supported
There's, anyway, a couple (of thousands) of opened issues to fix before "popping champagne". For instance, why the hell reading depth buffer with glReadPixels() and putting it into the frame buffer (as luminance) using glDrawPixels() does not work? I'm surely missing something... but what?!
