I finally got a working vwarp() patch. It just adds a new function,
vwarp(POINT, WARPS), which acts very similar to the vtransform function
except it applies a warp to a point. This image uses a black hole warp.
However, there seems to be a memory leak somewhere...it might be in one
of the other modifications I made, though.(Some code from a
(non-functional) pattern blurring patch is also in there, as well as a
vinverse_transform() patch.)

This looks like it could be **useful**, combined with a Perlin noise
function.....

Try using noise3d()...I wrote a patch which allows the noise function to
be called outside isosurface functions, and it is included in MegaPOV.
You could also use eval_pattern()(which is also included in MegaPOV),
that way you could use granite, wrinkles, etc.(bozo, spotted, and bumps
are identical to noise3d())
