Getting mouse coordinates
Author
I want to be able to select objects using the mouse and opengl. I know there is a way with i think glaux. I want to know if there is another way (that is easy?)? Does anyone know? Please Help! thank you!
One way is to use the GetCursorPos() to get the mouse coordinates, and adding some more code to your LRESULT CALLBACK WindowProc() that would handle events such as WM_LBUTTONDOWN (if you need that kind of control).

If you want to select objects with your mouse, it would probably be better to use picking. NeHe has a tutorial on picking and object selection, and so does GameTutorials. Check them out!
