Hi everyone,
Kudos to the Pyglet developers and contributors. The ability to handle
opengl and different types of media with minimum external dependencies
is great. I programmed a little 3D opengl test for the alpha 1.0
version. One problem I've run into with the alpha 2.0 (as well as the
just release beta 1.0) is that I cannot see 3d cube spinning. Any
advice how to make the code run with the new releases?
Regards,
Ruben
