How does this work? I need to make a system like that for DBC. If you know the screen height and width and the distance of the 'eye' of the camera to the imaginary screen which the view is pasted on, then you should be able to work where the mouse is pointing to in 3D space, am I right?
+ Code Snippet SCREEN
