> What is exactly Pz ?
Pz is the distance from the camera plane to the plane that the shaded
point is on (parallel to the camera plane; the camera plane is
perpendicular to the camera viewing direction and passes through the
camera position). It is *not* the 3D distance from the camera to the
If you want the 3D distance, use P instead (a point). Take the length of
that vector and you've got the proper 3D distance (this can be done in
VOPs or COPs).
