I have mapped the red ball of the bottom top-view 2D table onto the top pseudo-3D table using essentially linear interpolation of the points. The red ball's X position on the 3D table is accurate. The *y* coordinate however is very wrong. See the ball on the 3D table isn't nowhere near the pharaoh's feet.

From what I gather, I need to take Z into account somehow, but I don't know how.

If anyone ( R0J0hound ?) has any ideas? I don't need texture mapping, just coordinate mapping.

Thank you
