[PyOpenGL-Users] Fade to black?

[Rene D. <il...@ya...>]

Hello.

I was wondering if anyone had an idea on how to do fade to black?

I was thinking of overlaying a texture over the scene and slowly 
changing the alpha this texture has.

But would that work ok on slower hardware?  If it is slow any other ways 
to do fade to black(or from black, or to/from white etc)?
