Never heard of Fractrace.

Then again, I've never heard of anything other than Fractint anyway.

Wasn't it "stone _soup_ group"?

A fairly simple way to avoid most of those water cylinders sticking out 
of the landscape at the edge of ponds, especially if those landscapes 
are rugged, is too drastically lower the MaxPondTests parameter. In the 
attached image I used a value of 5, instead of 100 previously.

Are you making a script that can be applied to any heightmap/terrain 
generically? I would like to use it in one of my projects.

As far as I am aware, Kirk's original code can be applied /as is/ to any 
height_field at large. I am applying it without change, only playing 
with the parameters. Is that what you mean?

Can we get a closeup of what the individual water cones and cylinders 
look like? I'm wondering if the result will still look good from a near 
distance.
