There is a method by which you can restore the screen space x,y coordinates

gluUnProject maps the specified window coordinates into object coordinates
using modelMatrix, projMatrix, and viewport. The result is stored in objx,
objy, and objz. A return value of GL_TRUE indicates success, and GL_FALSE
indicates failure.

I tried this but i have not been able to get it to work so did all my transformation math myself and used screen space coordinates to retrive my x,y,z values.

If anyone has been able to make gluUnproject work do post a code sample in here for reference.

Thanks
Gopi
