Hello,
Here are some example shots from hf_tools.inc, which I just dropped at
p.b.scene-files.
The top two images show the edge pattern at work. The edge pigment in
the upper-left image was rendered at less than one third quality; it
does get better than that :) The upper-right image is using a
pre-rendered edge map at full quality. The edge radius is adjustable.
The bottom left image shows the superellisoidal pigment encasing a
height field. It lets you make smooth transitions from height field to
plane, while keeping more detail at the corners (as opposed to using,
say a spherical pigment).
The bottom right image shows how an angle map can be used to transform
textures according to the different angles of a height field.
Just a few features. Maybe they will prove useful...
Sam
P.S. The upper-right image shows some strange behavior at the height
field's edges. POV-Ray is handling image maps incorrectly, I think.

Well, that is easy for us to cut off in a difference or intersection.... :-)
This is really incredible. I need to experiment with this now!
You rule, Sam! You rule!

Awesome! When I saw the upper right and lower left image, I instantly
thought "Afghanistan!"... yes, this tool would be great for rugged
desert landscapes on DM +19 279 e XI (or Ghurghusht, how it is called by
its colonists). For real Afghanistan, I better rely on actual elevation
data... but perhaps there might be a way to enrich them with small-scale
erosion details!
See you in Khyberspace!

WOW!
That top left one looks like a polycrystalline surface under high
magnification, it already looks useful!

Not yet! Maybe my second cup of coffee will do the trick ;)

I hope you know that this file _does_not_ produce erosion... That height
map is an example I included from World Machine :/

That's the best way to be, at least until you learn the tool's
limitations ;D

Yeah, but it's an annoying way to go about it. You can always use the
boxed pigment to cut off the edges while building you HF.

After reading Yadgar's reply, I started to worry that everybody thinks
this file can produce erosion... it cannot... It only does what I said
it does, plus some near-useless red/green functions that I'm not
particularly proud of :/
