Hello everyone! Thought I might as well post this one....

It's a wooden block made from six intersecting height_fields. The 
texture  uses a proximity pattern derived from an averaged, randomly 
translated object pigment of the same wood block. The proximity pattern 
is like a blurred version of the object in 3d space; it can be used to 
make physical edges appear chipped and scuffed through texture_mapping.

Questions and comments are always welcome~

That's really awesome. I'm not sure I understand the proximity pattern bit.
Did you take an object pattern and then distort it with noise, and then use
a texture map based on that?

Brilliant!  After consulting the docs and rereading your post a few times...
I think I can grasp the concepts here.  Please do elaborate for us or post
the source.  The object pigment is being distorted and blurred and then
applied to the original shape to produce the affect right?  Its not the
height_field input itself being blurred and translated.  This should work on
meshes too, as long as they are solid/closed, right?

Yes, please post these.  :-)   My only suggestion on how to beautify this
image, would be to increase the camera "angle" because it almost looks
orthographic...

Regards,
Hugo

I think a source posting is in order here.... I need to make a simpler 
example that will work as a spring board for ideas.

The object pattern is blurred by averaging it with a pigment_map. Each 
copy of the pigment is translated randomly. No distortion is performed, 
but can be if needed. The resulting 3d texture can then be placed inside 
a pigment_pattern{} block whenever I need it (typically pigment, normal 
and texture staments).

Nope.

It works with *any* object you can declare.

I realized this... Sometimes the numbers can be a little touchy :)
