I don't think I've quite gotten the gist of it, and my program still doesn't quite run right (yet), but what I can say is that you guys have pointed me in the right direction and hopefully I can keep going from there, and hopefully towards doing some cool rotations.
Thank you guys. Now back to the grind. On 22 abr, 15:23, Casey Duncan <[email protected]> wrote: > Also note that the default pyglet projection is orthogonal.
