Hello,
I have read a few posts on this group and parts of the pyglet
documentation and I cannot figure out if I am doing this correctly or
not. I have written a small sample program that animates an RGB XYZ
axis. Currently my test program behaves poorly on my computer (the
animation is fairly jerky). I am using schedule_interval to update
the rotation of the axis model while drawing the model in the on_draw
event. I am updating the rotation by using the dt value when I
calculate the rotation. I have a Intel Core 2 DUO, Windows XP, and an
ATI Radeon 4870 GPU. Any feedback would be appreciated.
