Just playing around with isosurface whirlpools...another thing that can
easily be done with isosurfaces but not CSG: multiple vortices.

What's the equation for that? Something with a spiral pigment?

No special pigment, just flat blue...or were you talking about a pigment
function? Nope, not one of those...
#declare Vortex =
function {
1/(sqr(x)+sqr(z)+0.3) + sin(atan2(x,z)*7 + y*10)*0.025
}
isosurface {
function {y
+Vortex(x+2,y,z)
+Vortex(x-2,y,z)
+Vortex(x*3+1,y*3, z*3+3)*0.1
+Vortex(x*3-1,y*3, z*3-3)*0.1
}
threshold 0
...
}

This looks really great. I saw the source and hope that one day I'll be able to
do/use these isothingies.

Yes, I meant a pigmnet function. Thanks for sharing the code.

I looked at the source, and whimpered...
Too much mathematics <shudder>
:)
Bye for now,

Yes, I wish we could have an archive of all these wonderful functions
people are coming across
I for one, just cannot come up with this sort of thing

thats the idea behind povray.co.uk - a functions section is now in the list
of things to do
