[PyOpenGL-Users] Re: [PyOpenGL-Devel] rotation problem

[<dri...@ya...>]

hi,
 
thanks a lot for help!
 
i tried using the glPushMatrix() and glPopMatrix() as suggested by the examples, but the coordinate system still seems to rotate. 
 
like when i rotate at initial position along x and y the rotation seems to be proper, but now after doing so if i rotate along z then my z axis seems to have changed ... giving a feeling that the coordiante system has changed?

also is there a way to get the updated coordinates of the rotated object?
 
regards

You'll want to push and pop a matrix stack to do rotation. You can find 
demo code for glPushMatrix linked here:

BTW, most OpenGL tutorials, such as the red book or NeHe will cover 
matrix-stack manipulations.

HTH,
Mike
