quaternions

worked out quaternion rotation after many months of head scratching... and its actually not that difficult but did require quite a lot of time coming to grips with it.

if you are trying to rotate something at a certain angle around each axis and things are not going right... then quaternions are most likely your solution.

posted some source on how to do this in processing using opengl, hopefully it comes in handy for someone.
