3d light rotation

I’m just getting started with OpenGl and already I have a problem. I need my light source to rotate in 3d with the mouse. I already have it rotating on the x and y axes, but I need the light source to go behind the object and then appear again. Any help?
Thanks.

Have you thought about moving it on the Z axis?
You can make the Y a fixed value, and move just the Z and X with the mouse

Just a thought…
