Is there a method to select an object with the mouse and change his position ?
well it is not that easy that you can do it all with one or two function calls.
you have to switch in a different render mode. sort of offscreen, but i can’t remember the syntax. then you can use glu-stuff like glupick…
the modification of the position you have to do yourself.
if you want to have an example give me a mail and i try to send you my example from superbible2, though i am sure that there are enough examples on the net.
cheers,

What you want to do is called ‘picking’. Any OpenGL reference (e.g. red book, Superbible) will have the information you seek.
Look in Selection & Feedback section of any OpenGL book. I use OpenGL Programming Guide - Third Edition
