[Pyopengl-users] patch to trackball.py

[Alastair (L. T. <liq...@op...>]

Hi PyOpenGL Developers,

First things first, Thanks for the OpenGL python class that you have all
created. It's very impressive indeed!

I have a few issues that I want to bring up,

1. trackball.py

I have been playing around with trackballing under C, and I find that
the trackball.py is horribly broken. It makes me wonder whether it was
included there by accident. After spending quite a bit of time looking
at it, I found that there were a fair number of bugs in it, which I have
fixed up.

The patch is attached. It's made against the PyOpenGL-2.0.44
OpenGL/trackball.py using diff -u.

Basically, the quaternion.py included has the scalar as the first
argument rather than the last as in most implementations. Other changes
are included in the patch - so I won't bore you guys here :)

2. Vertex Arrays in PyOpenGL 2.0.44

Are the working ? I just get seg faults everytime I try glDrawElement()
and others ? Maybe it's just me :)

Thanks guys,

Alastair
