Just over 2 years ago, I posted some images of 3d strange attractors I'd
found, in this thread:
http://news.povray.org/povray.binaries.images/thread/%3C4b1c3281%40news.povray.org%3E/?mtop=333040
I recently returned to the project, improved my workflow (such as it
is), spruced up the plotting a bit, added some more equations and so
forth. I'm building a simple online gallery to house the resulting
images, which I shall post here when it's up to scratch.
In the meantime, here are some more fruits of my experiments. The most
frequently pleasing and quickest to find appear to belong to the
Pickover and Lorenz-84 equations, but the polynomial 'abs' and 'sin'
produce some wonderful angular, crystalline shapes if one is
sufficiently patient.

Wow, these almost make me want to revisit my own attractors again... maybe
someday :)
Beautiful stuff Bill!

LOL, I just glanced at these on my monitor from across the room and
'polya_web.jpg' suddenly reminded me of the flying spaghetti monster from
Lighting Challenge #10 over on 3dRender.com:

Superb lighting work! Proves once again what an excellent and versatile
tool POV-Ray is.
If I'd had to guess, say, five years ago, I'd probably have thought them
to be photographs of some shotcrete-on-wireframe sculptures or the like.

Beautiful alien sculptures!

Very cool, Bill. I especially like "polypow_hawk.jpg," which indeed looks quite
crystalline, almost like intersecting pyrophyllite or talc shards (if it were
green, that is).

Thanks! 2 area lights, colours and positions seeded by number of points, tweaked
by hand until they look good (lots of lurid purple & green combos discarded!).
Radiosity pretty straightforward, with a 50% grey sky.

I had to wiki shotcrete - I thought of expanded polystyrene :) It'd be great to
see these rapid prototyped, but I have no idea how I'd export them... last time
Darren suggested stereo pairs, which I might try.

Of course I meant polynomial 'power' not 'sin' :) I'll take your word for the
geology!
I'm finishing rendering another batch at the moment, once they're done I can put
the final touches to the gallery. It's just a shame the crystalline shapes take
so long to find...!

A "frozen" effect really nice. A tribute to Lorenz?
