| What is a 'skin texture'? Can't you just use a normal?

Just means it's surface-only, as all textures usually are.  Can also stand for
uv-mapped texture I believe.  I'd think that a 'normal_map' or similar would be
all you could do in the official POV-Ray, unless layering planes, however
there's a good chance that what you want to do can be done using unofficial
MegaPov 0.4 [http://nathan.kopp.com/download.htm] 'isosurface' as plane with a
pigment function since it isn't as limiting as HF in it's structure but then you
can't use a slope-based texture.  So it's a decision to make there.
Examples can be found in the povray.text.scene-files group I think and in the
HTML or Help files, also check out Samuel Benges' isosurface tutorials:

I have created a pretty swanky texture which simulates how a desert or
river-bed dries and crackles up. However, it is a skin texture (which I
have applied to a plane): and where the cracks are, you can see through
it. What I am trying to achieve are extruded segments, so that the
surface has depth.
As far as I know, all POV textures are skin textures - so, whatever
transformations I do to them, I assume that they will always remain as
skin textures (i.e. although I have it on a plane, a 2D surface;
applying it to a huge cube, and transforming the texture so it has depth
in the appropriate axis won't do me much good). I tried doing the
upside-down ground fog trick (underneath a hollow plane), but that
didn't work at all.

Other than using a height map (which is just kinda inconvenient for the
scale I'm talking about), I can't think of anyway to do this... Does
anyone have any suggestions?
Thanks :^)
