I've substantially updated my isosurface tutorial at
<http://www.econym.demon.co.uk/isotut>.

There's now an almost[1] complete catalogue of the built in functions,
and each page now contains a zip file of all the sources used for the
images on that page. So pop by if you've ever wondered what the Kampyle
of Eudoxus looks like, or want know what various parameters of the
func_16 surface do.

[1] I'd be glad of any hints on how to use any of the remaining built in
functions, namely: imp_func, data_3D_3, data_2D_3, data_3D_1, data_2D_1,
odd_sphere and iso_pigment.

Btw, the quartic saddle at http://www.econym.demon.co.uk/isotut/builtin4.htm
is missing the function definition.

Looks very nice.

For trivia, I think the func_11 is the density function for electrons in the
d orbital
of an atom. My physics is a tad rusty so I could be wrong.

Very good tutorial in deed... More than i need to know right now, but all
very fun and interesting all the same...
That said... I have a question...?
Why is there such a difference w/ the vers. 0.4 & 0.5... Namely w/ the
ridgedMF,hetroMF, & ridge functions...?

I will post an example of the "ridge" function in p.b.i...

Probably because the POV noise function was fixed for 0.5.
Those functions use noise intensively.
