5 hours 2 minutes and 10 seconds on a Pentium 4 1.4Ghz, WinME.
My Athlon 1.3 Ghz at home is faster, but I ran this at the office.

All right, I'm going to buy a new one.

We just got a new used computer store in our town, PII 200-400s in the
$20 range. I am thinking about setting up a small network just to send
renders to a spare 400.

Do they ship overseas? If so, how much do they charge?

I doubt it, but I could ask. They buy replaced equipment from
corporations, surely that is happening in other countries, if not now, soon.

Oh it's happening alright, but not anywhere near the $20 range...
Anyway, if it is a local store I also doubt they would be willing to engage
the paperwork hassle that the Brazilian government would unleash at hem like
a pack of rabid dobermanns...
Thanks,
Ruy

Yeah, I hear that shipping and import would make the price back up to
the $2000-3000 range.

Nice function!

I just did, it too the same Celeron 600MHz 128MB RAM I use at work, at
1024x768 AA0.3, just 2h14m53s, as opposed to 7h8m27s I got with the previous
version of the equation, or only 31.5% of those 7+ hours.
I haven't taken the time to study both equations, so excuse me for being
lazy and asking the question: how come?

Sorry for the late reply.
The best function for "isosurface" (the method 2 in MEGA POV) is a function
which
has constant gradient, for example, f(x,y,z)=abs(x),
f(x,y,z)=sqrt(x^2+y^2+z^2), etc.
(The function in the POV help file (6.5.4.2) is not the best function for
"isosurface".)
In some cases, you can increase the rendering speed by combining such good
functions.
