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!

Yadgar

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 :/
