    Transformations

    I want to do some collision detection in a graphics engine ... Before using OpenGL I would do the transformations and rotations myself and then use the new coordinates to check for plane - point intersections. With OpenGL I use the glRotate and glTranslate functions and can't figure out how to get the desired transformed coordinates to do my collision detection... Any help would be greatly appreciated.....

    Re: Transformations

    You'll need to do your own transforms in parallel. Don't try and retrieve concatenated matrices using glGet - people keep on asking about this, and it's terrible for performance.
