I hope I understood just what you were saying about the noise3d. If
indeed I understood you correctly, you wanted a sphere that has a thick
center while remaining to have a gnarly outside, right?
I just blobbed together an average, but small sphere with a normal sized
one that has a lot of noise3d. I also fooled around with strength ratios
between the two objects. The "&(y+1)" is just a plane I intersected the
object with.
Code:
isosurface{
function
(
(x^2+y^2+z^2+noise3d(x*8,y*8,z*8)*8)*
(x^2+y^2+z^2+.5/100)
)
&(y+1)
threshold 1 sign 1
}

Wicked, mon. I was looking for something like this. I wanted to shoot my
pathfinder algorithm at it and see if it could actually turn away without
hitting the center. I'll play around with your parameters: I wanted
something a lot bigger with more porosity at the beginning and a very gradual
increase to 100% density.
I also think that this type of feature would look cool as fire or a sun. When
I was asking for pointers on fire-based shapes months ago, this is what I was
actually thinking of.
Thanks.

Ah, all that kick-ass patch stuff.
POV 3.5 will kick-ass.
