Thanks... Hmm, your comment is making me think about height field mazes.
It might just be possible with arrays and a variation of Tek's Cells
pattern...

I hope so :)

It looks like it can be prety usefull. I'll play with that one.

Did you use the "once" keyword? Otherwise the image_map will repeat and
the value at 1.0 will be identical to the value at 0.0 by definition.

Yes, I tried that. I also tried using repeat warps with the flip
command, in the hope that mirrored edges would eliminate the problem. In
theory, it should work, but it doesn't.
I really need to make a small functioning example to provide along with
a bug report.

The edge map is probably the most useful feature :)

I may be talking nonsense here, but those same features are often also
created by WM or GeoControl. I don't remember them from Leveller, but it has
been a while since I last used that app. Do you think they have the same
origin? Are they the same kind of bug?
In GeoControl I can correct manually with a brush, but in hf's from WM I
just cut off a thin slice around from it by using an intersection in POV.
Not very elegant as a solution but it works.

Where was this years ago??!! You've created some real magic here. It must be
the coffee--drink lots more, so you can come up with more cool ideas!
I'm really looking forward to trying this out (and looking over your code, to
glean some ideas from 'the Master.')
