[PyOpenGL-Users] openglcontext.trackball

[gabor <ga...@z1...>]

hi,

i'm trying to use the trackball.py from oglcontext,
but there's something i don't understand..

as i understand, these track/arc/whateverball routines allow me to
easily move the camera around an object... so that the camera basically
moves on a sphere around the object...

but why is the camera orientation needed as an input?

if the camera moves on a sphere looking at a certain point, then the
camera orintation can be calculated from them... or not?
