Question : OpenGl, Screeen xy to real world xyz?
|
|
I'm fairly new with OpenGl. Now that I have display on the screen in the orientation that I want, I need to take a mouse pick, i.e. screen coordinates, and get real world coordinates. Are there functions to do this? I don't see them if there are. I understand that going from the 2d world of screen picks (x,y) that there is not a unique XYZ in 3D but I can deal with that.
Thanks!
