If you''re developing in windows, you can respond to the window events WM_MOUSEMOVE and WM_MOUSEDOWN...

I''am developing under linux, but this was not my question.
I''am able to capture mouse coords with glutMouseFunc(), that give me x,y.
But now I want to determinate witch object I''have fired to?
How can I determinate if mouse (x,y) coords are corrensponding with opengl my object ?

I''ve never actually done it, but the book I just read called "OpenGL, a Primer" by Edward Angel has a section on it. Basically you have to re-render the scene in a special selection mode which allows you to collect hits for a particular clipping region which corresponds to a rectangle around the mouse. Sorry I don''t have more specifics, but maybe this will point you in the right direction.
