Getting Where the Mouse Clicks in OpenGL?

[theopfor]

Hello, I am making a OpenGL game in C++ and it relies on where the mouse clicks in the 3D space for movement, placing objects, and probably other stuff too. I can't seem to figure out how to do this though. How do I find the coordinates where a user clicks?

You could use glutMouseFunc() to set the callbacks.

Here is a GLUT tutorial for mouse events:

Keep in mind that opengl is only for the graphics, the windowing library you are using can provide you with information where your user clicks within your window. (but you'll probably end up with a 2D coordinate...)

I think that might be what I need, thanks!
