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.
