[pygame] PyOpenGL Screenshots

["Ian Mallett" <geometrian@xxxxxxxxx>]

Hello,

-I have a project which must be finished by Thursday.  The project is a movie, for a presentation, and my solution has been to make a program to render each frame in OpenGL.  I can now render each frame individually, but now I face the challenge of turning these renders into a movie.  (Movie capture programs are no good--free ones have drawbacks, and in any case the renders are slow to update (think 1 fps tops).).

-I decided to do it as a .gif animation, as I have several programs for making movies from a series of images.  
-The obvious thing to do is to copy each frame into the programs, building my movie that way.  
-However, there are exactly 1200 frames in the movie at a minimal quality--that's (150 frames/scene)*(8 scenes).  I want this framerate to be higher.  This pushes the frame count higher, naturally.  The stupendous number of necessary frames is impractical to copy via ALT-PRINTSCREEN--(my current method).

-The ideal solution is to directly export the frames into a .gif animation.  
-My second best option would be to save each render in a separate file.  I could then drag and drop these renders chunks at a time into my program to make the animation.  
-I face several challenges here.  The most important is that I have no idea how to save screenshots from PyOpenGL.  Last I heard, people sort-of had ideas about how to do it.  pygame.image.save() does not work on OpenGL surfaces.  Any concrete working examples here?

-Summary: From an PyOpenGL program, what is a working method of saving renders to either many files or directly to a .gif animation?

Thanks,
Ian
