Picking

Does anyone have any idea how to extract useful information about of an
OpenGL picking call? It seems that the data returned while in GL_SELECT
mode is only very rudimentary. It returns in the Pick Buffer only the
min/max z coords of the polygon that was picked and the user ID value.

Is there any way to get accurate pick information such as the *real* z
coordinate of the pick, or the world x,y,z coordinates of the pick? How
about the UV value at the pick point?

Thanks-

-Brian
