View Full Version : Mouse feedback

Hi People,

I'm developing a 3D CAD system. OpenGL will be used as a visualization engine. Also I need to handle mouse clicks. So I need to do "unprojection" of screen coordinates into 3D-space on a fixed 2D-plane.
Have anybody had experience with that?

Thanks,
Uladzimir.
