NOTE: This Post was a reply in the http://www.fractalforums.com/images-showcase-(rate-my-fractal)/interior-shots-of-the-mandelbox/ Thread! Impressing images, twinbee! I love the excellent shadows. Lowering the Bailout could be like "ruins after some thousand years", maybe. There are lots of options, astonishing. Tglad, are the last two ones still the default formula? Nice locations. Just took a timeout from programming and did some experiments, i present a kind of "bulbox" Only change is to use the bulb formula when square of R is below 4... all cut at Z=0 scale=2 scale=3 (this may be also a 2D option with default and perpendicular Mset + some other 2D sets?) scale=3 and multiplying the values for the bulb by 10 zoom into and using the bulb formula when R is below 0.04 same, but using minR of 0.25 for the box

Wondering, if there are more "flying chickens" somewhere in the last one

as you might have noticed, i took the time and split this topic in a completely new
again amazing, i think this method can be used in a more general manner, i am a fan of combination methods of formulas, like alternating a formula, but this method offers new possibilities: define some radius treshold, and use completeley different formulas for each of these thresholds, here we would have 2 formulas, the box, and the bulb! finally a method i can implement using UF5 reb.uld Quat formula, with object codes, will send impressions this evening !
Jipiii!

OK David, now I want to be able to do the flying chicken in the amazing cube with 3D ferns and Menger sponges all around. Is that possible in a single layer?

here are 2d slices of: first: a mandelbox and a mandelbrot formula in 2d plane second: a zoom somewhere third: a mandelbrot^8 and a mandelbrot^2 at an separator distance of 1.0 the brot8 and8 combination yields interesting results when played around with the parameters ( i am with gpu here )

Excelent - I was contemplating the same idea to put a Mandelbulb in the middle of every Sierpinski Tetrahedral space I did essentially the same thing in 2D a while ago but just using 2 IFS fractals, including wrapping the image around the standard Mandelbrot: Very nice, i want a slightly different bulb in each round hole in the Box, where now is a little cube instead So we had just one formula with all possible bulbs which parameters are varied by the specific location...

Good idea, here are the alternating results... first iteration bulb: middle detail: first iteration box: zoom:

Testing the reverse mode: doing the bulb iteration on R > 2 and scaling the bulb by 10... refections inside the bulb from the outside because of the spheric folding???

What's the radius of that little "Mandelhole"? If it's equal to 1/2, then I'd be willing to be it is... is there any way to check easily with the software you're using to render these? Personally, I would love to see the Julia Set of the fractal... I'd expect it to have an infinite number of these little holes... A real Swiss cheese Mandelbulb.

Someday, man will understand primary theory; how every aspect of our universe has come about. Then we will describe all of physics, build a complete understanding of genetic engineering, catalog all planets, and find intelligent life. And then we'll just puzzle over fractals for eternity.

A tip for the higher order ones (z^4 on up): set your scale value lower. Lowering the folds and other values can help renders too, but you lose more details that way. Learned about the scale thing 5 days ago (at around 4am... go figure, there's that time again) when I was making the first full-hybrid rotational/amazing fractal types over in this thread. I even mentioned trying the bulbs in the very first sentence of the thread.. so you know. Anyways, I prefer hybrid type D because it reminds me of old video games I used to play, but this one is nice as well. Here is a series of z^3's with scale = .5 (Trifox, made them with low quality jpeg so they take up less HD space) Bulb type 1, bulb type 2, Type D.1, type D.2: Then some z^5's, same order Bulb type 1, bulb type 2, Type D.1, Type D.2:

OMG, great new variations O.o
Those bulbox mixes are amazing!

Ah, now i found the code, i think type-D is the second code in the thread you mentioned... So you already did the alternating hybrid, very nice! I guess i have to program this in a general way, choose 2 (or more) forumlas in a row. I like these hybrids. And yes, too high scale values would thin out the structures too much, as can be seen in my versions.
