Does anyone have any ideas how to generate IFS fractals in Povray.

Yup - but only really easy ones. I had a go at it the week before last -
basically by following the fractint docs.
The method goes something like:
Get an array of transformations.
Choose a starting point.
Pick a transformation at random from your list.
Transform your point.
Place a sphere (or for added fun, blob component) at your new point.
Pick a transformation at random from your list.
Transform your point.
...why don't you fill in the rest yourself?
I made a nice Sierpinski style Swiss cheese thing with this method. I would
have posted some pics, but I got sidetracked by other stuff in fractint
(isn't it great?), and forgot about it.
I can post code for the above once I've found where I left it. Would that be
ok?

Yes, it is great. It does not run too well on my XP machine, video driver aren't
too clever and it's slow in a DOS box. I was thinking about doing something with
IFS's generated with IFSSPELL

Yes that would be great. It would give me a starting point.

I have to boot from a rescue disk before it works at all, but it's almost as
much fun trying to figure out the docs, then implement the stuff in pov.
I've kind of got inverse-julias working in quaternion space. The
relationship with povray's julia_fractals isn't as close as I'd hoped, but
they're still pretty nifty. Maybe I'll share something one day :)

It's on text.scene-files
not very complete I'm afraid, but I hope it's some use.
All the best,
Luke.
