Heightmap to brick converter?

[Roland Melkert]

With many thanks to Roland, here is an example of a complete script to generate a kind of landscape with a "height map" from Excel.
Excel source and LDraw file attached.

Fun

I was playing around with actual landscape generating last night using a "Diamond square algorithm" lua module I found somewhere.
Unfortunately it was too slow (due to the hard coded max script run time) to generate any real sized ones.
