There are some great shots of the interior of the mandelbox (http://www.fractalforums.com/3d-fractal-generation/amazing-fractal/) lately, so I thought to gather some here-

These are amazing. They're like fractal architecture. I can see these being used for SF spaceships and for video games.

I would really love to see the plane "clenched" between the two pairs of teeth in that last pic. I wonder if it actually is (heaven forbid) smooth, and if not, what fractal structures it contains.

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.

Its not smooth  smiley even with lower iterations. In the ani you can see how pieces are punched off.
21 to 25 iterations:

I guess, to explore this, one will have to be even more creative than for the Mbulb....

Indeed! I have hard time finding some nice flight path  sad

I actually meant because the interior you cut open there seems even more interesting than the surrounding eggs...

However, that's something to be done a lot more with the Mbulb too: Cut it open. smiley And not nessecarily with a plane.
Most interesting would be if you could somehow seperate the interior based on special details in order to be able to work like a surgeon... Maybe a bit a morbid comparison but the most interesting interior view in an animal body is sorted by its organs.

A 2D-set doesn't quite have something like that, but a 3D-set could easily show them... smiley (Well, also just in the skin ofcourse... Or was there any try yet to find an equivalent of colouring the interior?

I understand what you mean. Sounds interesting. The images in this topic are really cool, and I can't wait to see more.

hmmm... thinking about it, the Buddhabulb would probably contain interrior details...

I don't have the anim version of UF, so instead here is a sequence showing a walk (or climb) through.
[sooty artefacts fixed on most pictures by increasing 'DE adjustment' from 1 to 10]

Starting in a corridor facing outwards


Walking forwards


Looking down into arch


Climbing down and peering out


Climbing through gap and into hall


Looking left


Looking straight ahead again


Climbing into the cradle


Climbing up to the top balcony


Into the arch


Crawl in and peer down


Squeezing in and looking straight down

Cool sequence. If you send me the file, I could try to do the animation.

David, do you know what causes the sooty artefacts in the first few images? If I turn on '0.521 method' they gets worse.


Nice shots smiley
Looking forward to bib's animation of it smiley

As to the spottiness, it's actually just luck really that the delta DE algorithms work at all on the Mandelbox, having said that I would suggest try increasing the bailout value - if you do so you may also need to reduce the solid threshold slightly and of course render times will increase, but hopefully the spotiness will go.

Thanks David, it seems higher bailouts make it a little worse. On average there are less sooty streaks if it is reduced from 10240 to 1024, but the colours change to lower in the spectrum, more greys and greens. I'm not sure why the bailout needs to be more than about 50... it is the square of the distance right... so on a 2d mandelbrot you could use 4? and about the same for the mandelbulb. How could a point out at radius 30 be inside the set?

Bib, a vid would be sweet cheesy, the sequence is here http://www.fractalforums.com/index.php?action=gallery;su=user;cat=131;u=853 in the description of each pic are the parameters.
