Wada Basin (Spheric Kaleidoscope)

Kram1032 · Post by **Kram1032** » Sat Oct 27, 2007 12:48 pm

One of the few fractals, that can get rendered by light simulation.
Modelled in Blender 2.45 with the lack of highly accurate tools, which lead to slight imperfections in the shape. Luckily, it's not very noticeable.
Rendered in Indigo V 0.9t10 (waiting for 64bit 1.0.1)
Great test for Indigo's AA

nearly 6h of rendering time and 530 spp, ssf 4, 4 threads

A higher res would certainly be interesting, but I'm not sure, if I gonna do that.

Edit2: Thanks for moving the topic, I removed edit 1

And I forgot, to mention, where I got the idea from

Well, thank you lyc, for the great idea

I don't need to link it, anymore, as he did, already

That is absolutely fascinating. What a brilliant effect you've acheived. I salute you.

Finally an image from you !

If that's not for something new... k well done

Wow, very cool.
Can you show us the scene setup?

ah, a familiar effect ;)

thanks lyc, for linking

I did it like this:
4 spheres, as good as I was able to get them fitting in a tetrahedron with IoR 100 speculars

black background light

3 mesh emitters, which are covering the spheres in an open tetrahedron
one 1 0 0 one 0 1 0 and one 0 0 1

(more Infos in lyc' links

)

thanks for the comments

I'm also quite satisfied

I tried a res 2000², now, but it didn't work: It ate more and more RAM, while building, without starting rendering.
After some time, it said "saving igi" - although there was *no* render output.
Then, I stopped, as it still didn't do anything...
Edit: It's working, now, with 1500²

Shall I post the igs?

so, here we go

after fiddling arround *far* longer than it was my intention (I didn't get satisfying results...), I finally got some useful stuff

From now on, with a new fresh avatar

I've packed the blend and the igs into one zip, for anyone, who wants

Btw: the spheres are primitives in indigo, but in Blender, they're still quite high poly, as I also rendered it in blender (with far less beautiful results

)

And here the loop closes again. What started my interest in computer graphics almost 20 years ago - her it is surfacing again.

That was unexpected, fascinating!

Thanks Kram and to all the others who have the time to dig up such interesting topics and bing them to our attention.

do you mean "fractals" or "wada basin" in this case?
thx

Headroom · Post by **Headroom** » Tue Oct 30, 2007 12:56 am

I meant fractals.

Kram1032 · Post by **Kram1032** » Tue Oct 30, 2007 1:08 am

ok

yeah, I love them, too

have to be careful with those addictive things, they'll make you forget all about life and writing unbiased mlt renderers, for years at a time! ;)

correction:
they do that to YOU

Although I already feel some of the preprepresymptoms

just you wait until i show you how to code some fractal renderers ;P
