Remember the "distortion field"? This feature is similar, but it is an
actual patch that implements a warp which does the same thing to a
pattern. The syntax is simple:
warp {
displace_warp {PIGMENT}
}
Here is an image of a displace_warped checker pattern(left) and a
gradient pattern(right). The displacing pigment is a bozo pattern with
an automatically generated color_map.

Ah, yes. I was playing with something like this a few weeks ago. You can
make subliminal images this way.

I'm not quite sure what you mean...was it a patch? If so, I would be
interested in what you came up with...my patch simply adds the "color"
vector to the position vector.
And "subliminal images"?

Thank you, thank you, thank you!
You have no idea how often I've wanted to be able to do this!

Io am just thinking aloud here.
As Tony[B] pointed out; the "classic" fire-demo-algorithm uses this kind of
displacement to mimic a very realistic fire-texture. And think of the
wonderful wood-pigments one can make:
pigment {
wood
color_map { something wonderful yet brown }
warp {
//something like; don't know the synatx ;)
pigment {
leopard
color_map { [0.3 color rgb 1][0.7 color rgb 0] }
turbulence 1
scale 0.2
}
}
}
I can imagine this creating displacements resulting in kind of like
blackhole warp, except distributed everywhere and turbulenced.
And why not do something like:
pigment {
image_map { your favorite picture of a nice person }
warp { spotted scale 0.2 translate z*clock }
}
to make it bubble like a hot witches cauldron!
Oh, don't get me started!!
Regards,
Simen Kvaal.

When will this make it into the next (?) MegaPOV-release?
