I noticed very different effects when making a noise3d-based object
between MegaPov and Superpatch.  I discovered a neat surface in
Superpatch and thought I'd try shooting some photons through it.
Unfortunately, Meg gave me some ugly results, even before I made it
transparent. . .

Any thoughts?

Here is the code used:

#include "colors.inc"
#declare fnoise=55;
#declare funk=
isosurface{
        function{y/50-noise3d(x/fnoise,y/fnoise,z/fnoise)
                }
           accuracy 0.01
           threshold 0.0
           bounded_by {
                      sphere{0,250}
                      }
        pigment{Red + Green/3}
        finish{ambient 0.2}
          }

object {
funk
pigment {Red + Green/3}
finish {ambient 0.2}
        }
camera {
  location  <0,200,-800>
  look_at <0,10,0>
  angle 40//35

}


light_source{<-40,400,-5000>rgb 1.2}
light_source{<2000,0,-35>rgb .2}

light_source{
 <0,200,-999> rgb .2}
