This surface renders painfully slowly, is full of artifacts and doesn't
quite look right:
parametric
{
function { sin(u * ( 7 + cos( u/3 - 2*v) + 2 * cos( u/3 + v ) ) ) },
function { cos(u * ( 7 + cos( u/3 - 2*v) + 2 * cos( u/3 + v ) ) ) },
function { sin( u/3 - 2*v ) + 2 * sin( u/3 + v) }
<-pi, -pi>, <pi, pi>
precompute 20 x, y, z
accuracy 0.0001
pigment { color red 1.0 } finish { ambient 0.5 phong 0.8}
//rotate y*45
}
I had read many times that parametrics where slow... very slow, I didn't
believe them until I tried one. I'm downloading the parametric inc mentioned
in one of the Isosurface tutorials.
From all appearances, I'm going to take a wild guess that POV3.6 has the
same issues.

Yep,
param.inc renderes REALLY FAST ;) Not only that, but I found an error in the
equation definitions. Cool. I'll post an image, soon.
