Description
"mating" of two julia sets (z^2 + c1) / (z^2 + c2) with a spherical surface trap, and some detailing...rendered with unbiased ("infinite bounce") light transport, in this case diffuse (radiosity) using my toy renderer, allura.
title taken from the amazing autechre song of the same name.

interesting! i would be interested to try it in my software if possible
on that note, i think today i might try to implement hybrids

Arghhh
It got on page 9 already
Please send me a note so it won't get drowned 😥

very much belated thanks! the first track of their new EP is so awesome btw

Maybe someday I'll know what you wrote under this to explain it, but until then I'll just fave it!!!
( No, I'm not going to start doing poetry now, no matter how much you beg me).

nope, i mistakenly submitted it to #gfxcoders , you should have an announcement about group deviations vs favs explaining it, apologising for confusion

programmer power!
i'm glad you like it

I could quite easily see this as a frame from an Autechre video (doesn't surprise me you're a fan, they became tremendously boring after Confield, but preceding that they are still fascinating). I can imagine flying down the opening to the lower-left and seeing further Julia patterns down a tunnel of some sort... Great work!

england is the musical capital of the world! well, the "fertile crescent" of the electronica scene at least
hmm actually it'd be great to do a collab sometime (if you'd be interested), wish i had some spare time and focus these days though, busy with work and too many other things... but, some of the stuff i work on may be used by you someday, if i play my cards right

hehe, that's why I moved to London, so many great gigs.
Id be very interested in a collab with you actually, what kind of thing did you have in mind?

well, me and a buddy (~greenhybrid ) are planning to write some fractal software, which will hopefully be fairly cutting edge and usable for high end animation work. so there's a fractal aspect to it probably
also, we like to write ray tracers, and like to generate procedural geometry. just add direction and art assets.
hopefully we could release the result, which would be a few MB that unpacks (given a cluster) into several GB of pristine 1080p and surround audio... that's my ultimate hope, we don't have to get it in one step
much as i'd love to just go ahead and do that tomorrow say, i'm already like 3x over-committed and have poor time management... so it would be in a few months earliest, i.e. just something to keep in mind while creating stuff and collecting ideas

sounds excellent man, I'm very interested in working with coders such as yourself. Me and a friend are planning on working on a live installation perhaps in the summer, he codes shaders and things directly tied to gpu functions. But that project is very vague at the moment and I don't know where/when its going yet.
On the other hand I'd also be very interested in any information you had on free ray-tracing software I can use for rendering some of my work. I tried out v-ray in the past but I'm more interested in something freeware which is either stand-alone or integrates with cinema 4D somehow.. or even 3D studio max, I still know my way around that.

woah... that looks intense. I'm gonna try importing a c4d scene now.

allura, a rendering engine i'm writing. thanks for checking out my best result with it so far

tis' quite nice.
You've piqued my interest with this one. Capabilities and purpose of writing Allura?

the realism stems from using a physically-based rendering system (as in it is a perfect model of diffuse light transport, using wavelength-based rendering with blackbody emitters instead of the usual rgb etc). you might like the fractals in my scraps btw, i have more rendered with this system.
about fractals existing in the world around us, there are definitely plenty of those [link] [link] (but in the case of the fractal presented here i doubt it very much 
👍: 0 ⏩: 1
Mmmh interesting, so you just associate a certain temperature to your light source and then compute the wavelength it emits? Is all that very hard to code? I've never programmed a real 3D renderer so I wouldn't know. What language do you code in anyway?
👍: 0 ⏩: 1
correct. there are also ways to convert rgb to spectral distributions, so you can use all the existing rgb data as well.
i code in c++.

Man... you hurt my head.
I am still baffled at how these are created. Are the Julias layered to get that effect or is that the formula itself?
so very beautiful.
*trundles off to get some coffee before his head explodes*
👍: 0 ⏩: 1
yeah that's a single formula, but its layers come from varying a parameter by height. i could also put it on a sphere (as i'm planning to do with this earth data to render space shots: [link] )
glad you like it mate
👍: 0 ⏩: 1
On a sphere it would look just amazing. Especially the parts that really burrow deep. I love how machinelike these are.

btw, there's a way to generate a 3d mandelbrot set, i've done some renders of those:
[link]
[link] (same object, different materials for higher contrast, view from the top)
[link] (a relatively thin slice to show the usual 2d mandelbrot shape)
👍: 0 ⏩: 1
I like the thin slice the best... really gives a good impression of the effect.

two years later that 3d "mandelbulb" set is famous
👍: 0 ⏩: 1
I am as fond of these as I am of the mandelbulb. I think the graininess of these earlier 3d archtypes is what turns a lot of people off from them. It doesn't make them any less technically excellent imho.
I find this one so interesting because it looks like 3d shapes trapped to an ifs, but somehow the shapes don't compete with one another. Their curvature fits with the underlying fractal formula.
I know it's piled slices, but the illusion still holds, which is what gives the mandelbulb a lot of it's strength visually.
I experimented whole heartedly, working with manual iteration changes across sequential layers in ultra fractal (and later photoshop) after seeing these fractals. They are very inspiring.
