Following a short thread in p.advanced-users, here is an example of
mapping a height field around a sphere with the pigment function.
Not a new technique per se, just notable for the use of map_type 1 in
the pigment definition (other map types and warps should work). Here the
image map is a text (white fonts on black background).
Source in p.text.scene-files, for Megapov 0.4.

Nice!
For info you can do this with a torus too...see arch in Portal

Very neat i am more and more impressed w/ the features of mega and can't wait
till they reach the official version...

A piece of advice for those who haven't figured it out themselves.
Using interpolation on the image_map reduces render times a really
great deal (makes finding the isosurface gradient easier).

So now if I could find a way to remap a sphere back to normal x,y,z
coordinates I could render image maps to smulate normal displacement. (Make a
sphere with a certain pigment, but remap the pigment so the surface of the
sphere is on a plane so that if you render that plane and map it to a sphere
you get the original result)

Spherical camera in MegaPov.
Put it inside a sphere.

I did that, it works very, very good. I made a half-way decent asteroid
earlier doing that.

So many features so little time!
It will be nice when all this stuff gets into official v3.5 or 4.0 and the
tutorial section covers it!

You may have a look at some patched Warp I made,
at http://www.altern.org/grimbert/pov/
There is not only a sphere, but a cylinder, a cone and a torus
(each time in both direction)...

Boy, you miss a couple of daze here
and all this stuff happens.
Let me get this straight.
Warp was in some kind of accident.
(I'm guessing one of those extreme
sports the 'kids' are into these days.)
He was patched. I am assuming
he is ok.
No big woop,

Rollerblades. Staircase. Railing. Sterile.
That is all you need to know.
