that's exactly what i was looking for... thanks!
It is interesting. Am I right in understanding that you basically have to
choose between Pygame's normal (SDL) drawing functions, like surface.blit,
and OpenGL's? You can't just draw a 3D scene like that of the code above,
and then blit an interface or text atop it. Instead you have to switch to
a 2D mode, turn your Pygame drawing into an OpenGL texture, and draw a
rectangle textured with the new drawing -- and delete/replace the texture
every time you want to change something. That's so cumbersome that I've
barely ever gotten it to work; is there a better way to integrate OpenGL
and Pygame graphics?
You're right that you cant use any of the regular SDL drawing functions
with OpenGL - or any other accelarated 3D API. You can work with 2D
graphics in OpenGL though, by drawing texture quads. If you wrap that
in a simplified interface, then the code doesn't look much different
from what you are used to in 2D PyGame.
