[JAVA3D] Picking - all help is appreciated

[Bruno Sousa Caiado]

Hello. I�m sorry for the "desperate" subject but i�m loosing my mind with this problem...   What i�m trying to do is to find out the (x,y,z) of a point when i click a mouse button   Finding out x and y is easy with the MouseEvent class.My problem is knowing the z value! If the mouse is clicked on top of an object that�s has z=10 in that point how can i find out this value?   All help is appreciated....   Thank you and keep up the good work   Bruno Caiado
