Nice. Fast. Beautiful.

Great job! Not that I really understand it, though.

	noisefunc(x,y,z,sqrt(x*x+y*y+z*z)

The sqrt() part is the distance to the origin.

	f_noise3d(x/dist,y/dist,z/dist)

And now you use the noise3d result of the current point, scaled with the 
inverse of that distance? Could you give some more explanation on how 
this works? All this function stuff is pretty new to me :)


Thanks!
Florian
