Welcome to Fractal Forums

  saw it with fractals sublime "amazing surf" but how
can you help me out please
padron to bother you again
greeting ERIC
how to use this feature
choose what PARAMETERS
please

I'm not sure if i understand your question, Eric.

i think he means where to find the amazing surf formula in mb3d, to my knowledge it is

3Da -> Amazing Surf

formula which has to be used for it ;)

Please don't just edit your post if you want to reply. Otherwise i can't see your answer in the recent posts.

Best start with the Amazing Surf:
Activate Julia and set 0,0,0 coordinates
Set Amazing Surf rotations to 0,0,0 and from Cylinder (value 1) to Sphere (value 0)
Now try only Julia Z for example (see what happens). Then try some single rotates. Check how rotations and Julia interact ... some slight rotations let a structure disappear but some slight changes of Julia bring them back again ... but in a different look. Even the interplay of fold and scale is most interesting. But i'm also just fumbling around ... be prepared to spend hours. ;D

Hope it helps for your start.

thank you
it help me

Has anyone rendered interesting pictures of the Surf (no Hybrid) in Mandelbrot mode?

is this interresting enough?

In fact I use a completely different strategy as lxh for example. I allways start out with an mset, 'cause I follow the slight changes in mset. First I fiddle around with Scale, Fold and rotation. Then I start to examine the different areas of the mset. When I see an interresting structure, I pick julia constants from the most interresting point and see what happens. When I already zoomed deep enough, that the changes of mset are minimal (or the julia set is almost like the mset), I just stay there... see above.

This seems a very interesting strategy. I will give it a try, Torsten.
But the surf renders so damn fast at low zoom levels that it's nearly too smart. :tool:  :dink:

I think theese two methods are barely comparable, both with pros and cons. Just tried to convert your (hybrid) parameter to an mset (julia constant as camera mids) nothing interresting to see...
On the other hand the one below should be hard to find without the mset, as it originates on an isle of order in a messy ocean of chaos (there are at least four in most mset configurations) beside the center. hard to hit just by flipping sliders...
I'll surely try some more julia work in future, especially as my mset method is more of a relict of my work with the mandelbox and mandelbulber. O0

Thanks a lot Torsten for the tip!

Always a pleasure. Hope you can use it! ;D

Torsten, any tip on how to move from the Julia to the M-set? Let me explain: say I found a nice shape in Julia mode, and now I want to look at the corresponding M-set area to get some variety around. When I go back to Mset mode, I get just strange noise. I put the Julia coordinate in Xmid Ymid Zmid and try to look around and zoom, but I see nothing like my Julia... Any clue?

Here are the params if anyone wants to try

I tried some params with julia coords as camera mids as well with no success.
I'd try to use julia coords as cutting planes. at the intersection point there should be the mset variations, as long as julia coordinates are not too far outside the mset. I have some mandelbox julias, that have no equivalent in the mset, "sea invader" is one.
I'll take a look, when I'm back from work.

just tried. this is the spot (i measured). as expected with zero rotations it is a flat disc. I think your parameter has no equivalent here. I don't even understand, why the julia set is 3d. Sorry!  :sad1: Maybe Kali can explain.

Thanks for trying it out. There's something weird going on :D

Not always Mandelbrot version shows a consistent map of Julia versions of the fractal. I learned this when I discovered the 2D Kaliset formula, as you can see in this post: http://www.fractalforums.com/new-theories-and-research/very-simple-formula-for-fractal-patterns/
I guess it's because of how julias are positioned and how it's position changes with the different values.

It's something to take into account when researching new formulas  :dink:

Kali, I read that thread and your discussion with Sam but I did not see any clear conclusion...Did I miss something?

I thought about this "anomaly" a little while. As Asurf is tight related to Abox, my investigations on Abox might be useful for this.
My expierience with the Mandelbox says following:

• For every Point on the mset surface (and solid spaces too), there is a correlated julia set, with graphically identical properties, BUT
• there are (non zero) julia sets, that are not mapped in the mset as their constants are outside the mset

There seem to be a (narrow) coordinate space outside the box mset, where juliaset constants lead to not empty juliasets. when they are far enough away from surface, they have graphically no equivalent struchture on the mset. Most significant example i found for such jset is this.

I think with bib's parameter it is similar. the mset is a flat disc in xy plane. every jset with non zero z constant is not mapped on the mset.
ps be indulgent with this attempt of a declaration. I am neither programmer nor mathematician.  :dink:

Mmmh, could that have anything to do with iteration count and bailout? Those "ghost" Julias are not real, I mean, we see them because of the DE stop, but in reality they are "empty". So what we see is a kind of "solid iteration fog". Don't know how to explain better, sorry :D

Just my 2 cents...

I think you got it!
The one below is very sensitive on changes of de stop. Decreasing it makes the arms thinner and thinner.

(terms like "in reality" are quite strange and funny in this context...)

No, you missed nothing, we noticed this fact but couldn't find why it happens... I pointed to that thread only to show an example of another mset "not working properly".

Now, my theory on your params is: When calculating a mset, for every point in space, the formula is iterated adding the same coordinate values of the point to be drawn.
I didn't test it in specifically in your params, but what could be happening is that for every Julia set calculated outside the x-y plane, the point located at the position matching the Julia constants, is empty. So in mandelbrot version, for every point x,y,z is like extracting that specific point from the Julia using same x,y,z as constant, and is the only part of the Julia that will be shown, so the result is mostly empty space excepting the flat surface when z=0.
Something like this should be happening with taurus example.

I hope I made myself clear, I don't know how to explain it better, at least in english  ;D

Also, I forgot to mention, about the DE stop thing... that happens because it's really a surface (hence the formula's name), so the fractal's volume is zero.
It's the DE approximation what makes it solid, but they are in fact 2D surfaces on a 3D space.
