Thanks for correcting me Chris, just now looked it up.
I was going by what I had believed since the time of POV-Ray 2.0, which btw was
6 for that version also.
Could have sworn I always read that it was 3, although maybe from looking at
all the wood patterns. Many textures probably use octaves 3. But guess I
can't be believed :-|

I'm really enjoying this sequence of pictures, such fascinating worlds.

Yes, you're right.
Octaves was one of the keywords I wanted
to see the effect of, but I see now that I
have used the frequency keyword instead.
I think I must have mixed it all up in my
mind. :(
And now I'm a little bit confused -
I think I need to look up these two keywords
again, just to convince myself that I do know
the difference.
And then I'll do test renders to see the
effects of different octaves values.
Thank you Bob.

Thank you Mick.
I can't help wondering how many more different
_types_ of iso-pattern world's I'll have patience
to explore with POV-Ray on a Pentium @100MHz
I'm sure there must be an infinite number of
different iso-pattern world types just waiting
to be rendered.

So how long did this take to render on your P-I 100 ?

As far as I can remember, this one rendered
relatively fast.
I usually leave POV-Ray rendering my iso-surfaces
through the night. (I do most of the test renderings
for these at 160x120.)
I think this one rendered somewhere between 4 and 7
hours.

Now I feel bad about asking you do re-render that
torus isosurface (all in blue with the red light) in
1024x768. On the positive side, I've set it up as my
disktop background at work and it has been getting
compliments from my co-workers. Thanks again! :-)

Don't worry.
I was very curious myself about how it would
look in a larger rendering.

I'm glad to hear this.
