I have a problem that needs a quick hack before ITSEC (read today).

I have a 3D surface that represents bathymetry. It has one transparent
value (missing data) so I believe it is stuck in the transparent bin. (I
THINK) Then I have a 2D plane that represents the water surface.... it
cuts through the 3D surface. At the shore I get polygons popping on top
of each other then behind each other.... very visually disconcerting,
especially in a CAVE.

Anyone got a quick hack? (This is old code, so I don't care if it
involves three typecasts and some assembly followed by 2 macros) When I
understand the hack I will sit down and really fix the problem.
