Title: The beauty of the interior of a minibulb
Post by: KRAFTWERK on January 14, 2010, 09:18:48 AM
I find it extremely interesting inside the minibulb, havnīt seen so many images from here.
Yesterday I found some better settings for the "inside" in Subblues pixelbender-script.

Will post the original (4000x4000 pix) on deviantart later...

I can see myself sitting there, with a cognac and a cigar, picking strange fruits from the walls  :D

Part of the scenery in high-res...

When looking at it I think it is like the Seahorse-valley of the 2D version, so much details to explore...

not so many details in this video, but some intersting views of the "inside" as well :

Your videos are supernice bib!
Most of the zooms I have seen here are ito the "skirts" of the "tower" like this one... if I can make a wish, I wold like you to do one, zooming into the minibulb, to the formations in my image in the first post, closer and closer (slowing down the camera of course) to new details.

My problem is that I run out of decimals in Pixelbender.... donīt know how many decimals you can handle....

Because my formula (and Ron Barnett's) are in Ultra Fractal, so they use the CPU rather than the FPU, they use doubles rather than floats, so a distance threshold of as low as say 1e-14 should be possible (even smaller if you enabled UF's arbitrary preecision but then rendering would be *very* slow).

OK, so getting the kind of Zooms you see of the 2D mandelbrot would require months of rendering i guess...
But it would be very nice to see something of the kind, just to get the feel of how "fractal" this thing really is...

I mean, just look at the "fruitbasket" strapped to a wooden log in the first image, to zoom in on that and find some new shapes to zoom in to... I must buy a supercomputer and UF i guess ;)

As I told Daniel White, it might not be the holy grale you have found here, but for me it is a solid gold one, and we still have a lot to find, things noone ever seen before (like the fruitbasket - it has been there all the time... =)

I am truly amazed

Well a view of a full Mandelbulb at say 1920*1080 needs a solid threshold of around 1e-3, using a threshold of 1e-14 does give quite a bit of scope for zooming, not quite as much as a 2D fractal but still pretty good ;)
Sticking to using analytical DE you could probably push the threshold maybe as far as 1e-16 without using arbitrary precision.
As you say, going further than that using arbitrary precision would take a long time.

Itīs just for our talented 3D-animators to get going then? ;)
Or for me to invest in UF...  O0
(How far has anyone gone in zooming stills? I know some of Daniel Whites renderings are rather deep, but I donīt know how deep)

And here ist another view of the tower, which is the "path to infinity" from the outer side.

a minibulb in the "garden" area inside another minibulb

YES bib, right answer! I really look forward to this!

I feel like a fruit-case myself... O0

Nice tower-zoom too! How "many decimals" are you down to in that one?

Where on the tower is that trafassel?
And (sorry if I should know...) what do you mean by "path to infinity"?

a minibulb in the "garden" area inside another minibulb

So this is the real thing? the "garden" area = the "garden" in my first image?

I don't know, I'm just using Dave Makin's formula for UF.

Yes.

Anybody has identified and classified the classic "zoo" of the Mandelbuld (whatever order) and their properties?
- Tower/Crater
- Garden
- Bulbs
-...

...and the things in the crater...???

With tower i mean the "Mandelbulb Spine" from the first mandelbulb page on skytopia. And the "path to infinity" is a picture in the gallery.

This picture is from the top of the tower.

Hey that really is (a front view of) the 'Spine'. Nice!

(Like the colours and shape in the first pic in this thread too, though it does look like an 'outside' pic ( ? ) ).

What shapes happen on the border between brocoli and tower? :)

And did I get you right? The first of the last two images is inside a minibulb of a minibulb?


Title: Re: The beauty of the interior of a minibulb

horrible compression but else it really looks nice :)
A lot of starting whipped cream on the right side ^^

Well, as far as i can see it is "inside" the minibulb (see image), so it is still "connected" to the outside, I did a high res panoramic image of the place this weekend where one can see through the round "hole" with a "christmas tree" (in the middle of the white frame) to the outside. I will post the panorama later today!

Bib:s image should be a minibulb inside a minibulb...
Mine is just the "inside" of a minibulb...  O0

Correct. But using Isokron's program, I could also go really INSIDE the minibulb of a minibulb of a minibulb of a minibulb (4 times before I hit the resolution limit) :)

Post by: KRAFTWERK on January 19, 2010, 02:39:24 PM
Here is the full panorama
It starts at the image you could see in my first post
And a still image showing that you can see the broccoli on the outside...
...therefore I am still at the outside of the bulb, but also inside a minibulb.
The original high-res panorama is a 987 MB Tiff-image ( 28490x12113 pixels)
So this is a very compressed version.

Those bulbous almost-spherical parts sprout much fractal detail before the whipped cream takes hold (similar to the smooth bulbous/elliptical bits on the standard 2D Mandelbrot).
