Generating a heightmap 2004-02-24 - By Lucas Meijer

Hey Ian,
That's a lot of things you tried there :-)
Normally, I let a maxscript generate my heightmaps.
Since you're making this scene using lingo itself, that gets a bit tricker.
one idea that comes to mind is this:
for each tile
aim an orthographic camera on it, from the top, making it view
exactly the entire tile.
set the camera.z to say, 1000
set the far clipping plane to 1000.
repeat:
render
if render = totally background color -> exit repeat
else bring far clipping plane closer
end repeat
this tile's maxheight = current clipping plane value (compensated for
camera position)
end for each tile
Other than that I think the easiest way would be to somehow export your
scene to a 3d authoring app, which should make a heightmap for you nicely.
Bye, Lucas
