Title: Mandelbulb and Mandelbox mix
Post by: Buddhi on March 12, 2010, 07:42:13 PM
I made experiment with mixing Mandelbulb and Mandelbox formula. I used cubic folding algorithm from Mandelbox before mandelbulb formula.
double scale = par.power;

Pseudocode:
if (x > 1.0) x = 2.0 - x;
else if (x < -1.0) x = -2.0 - x;
if (y > 1.0) y = 2.0 - y;
else if (y < -1.0) y = -2.0 - y;
if (z > 1.0) z = 2.0 - z;
else if (z < -1.0) z = -2.0 - z;
new = MandelbulbFormula(x,y,z)
x = new.x + cx;
y = new.y + cy;
z = new.z + cz;

result:

Is that pwr=2? What does pwr=8 look like? (Or vice versa?)

this looks nice :D

Very organic :)

Yes, it is pwr=2. I will try with other powers and formulas.

Below there is some close-up. It is much more irregular than normal Mandelbox.

this looks amazing :D

It mixes the architecture-like structures of the box with the organic brocoli-ish shape of the bulb and the result is an organic-mechanic structure :D

You asked about power 8. Please look at image below

hmm, if played with it a bit, this might possibly be brought in the shape of really working fractal gears :D

I have changed a little folding conditions. Now are:
if (x > 2.0) x = 4.0 - x;
else if (x < -2.0) x = -4.0 - x;
....
etc...

It looks completely different. Now there are visible 27 separate bulbs and lots of small bulbs around each bulb.

I have just released new version of Mandelbulber with these formulas

It's like a whole system of planets with vegetation :D

I'd love to live on one of them :D

As far as I can tell, they all look different, right?
Are they ordered in a cuboid way or a little more organic?

EDIT: Oh I see, it's actually spheres, made of smaller spheres, made of...
Well, still interesting to live on one of them :D

Wow, I can't believe the delicate equilibrium of detail survived the merging of two quite different techniques!

Great find. Worlds within worlds...

Thank you for nice comments.

Next image shows Juliabulb power 2 (c = {-0.6, 0,0}) with folding function:

if (x > 4.0) x = 8.0 - x;
else if (x < -4.0) x = -8.0 - x;
...
(the same for other axes)

Interesting is that now there are visible structures similar to high power Mandelbulbs although power = 2.

So this is not a Mbox-folding?

Or are those conditions similar to those from the Mbox?

I somehow always missed the basic Mbox formula^^

This looks great, like a lot of connected fractal ball bearings :D

It's very interesting how this kind of fractals mix organic and mechanic look'n'feel in a very new way :)
(For instance, a car, especially a sports car but basically any modern car, looks very organic and mechanic at the same time but this fractal has that property in a totally different way)


Title: Re: Mandelbulb and Mandelbox mix
Post by: Buddhi on March 16, 2010, 08:44:23 PM
It is a Mbox-folding but only cubic part (without spherical folding)

if (x > 4.0) x = 8.0 - x;
else if (x < -4.0) x = -8.0 - x;
if (y > 4.0) y = 8.0 - y;
else if (y < -4.0) y = -8.0 - y;
if (z > 4.0) z = 8.0 - z;
else if (z < -4.0) z = -8.0 - z;
new = MandelbulbFormulaPower2(x,y,z); //or other 3D formula e.g. quaternion
x = new.x + cx;
y = new.y + cy;
z = new.z + cz;

A pretty simple set of if-rules :D

These are both brilliant and beautiful.  The color and lighting in the renderings are quite artistic and stunning too.

I was just thinking... in combination with "Amazing fractal" (which seems kind of to have died out), and "Mandelbox", I think "Cantor Cube" is another fitting description. It is nowhere dense, (unlike the Mandelbulb), and it takes the form of a cube, like 3D cantor dust. The difference of course being that it's so much cooler.

Hi, here's my attempt using Tglad's cubic folding used by Buddhi.
Made using Subblue's mandelbulb.

Interesting animation. Which parameters did you animate? Folding limits or Julia constant?


Title: Re: Mandelbulb and Mandelbox mix
Post by: visual.bermarte on March 28, 2010, 04:03:37 PM
Julia+Radiolaria+Power+camera position and zoom.
It's possible to use variables+sliders for folding's values as well.


Title: Quaternion Mandelbrot and Mandelbox mix
Post by: trafassel on April 24, 2010, 09:06:14 PM
Same combination as Buddhis. First Quaternion, then folding in the box (no sphere folding).

Scale = 2

Here's part of the standard z^8 "-sine" Mandelbulb with the standard scale 2 Mandelbox transform applied first on each iteration (rectangular and spherical folding and the scale):

Negative power morphing-test.
Made with Tacitus + TTG(GPU rendering).
