Welcome to Fractal Forums

Bonjour
I am new to this forum and to mandelbulb3d
I have copy with notepad some formulas coming from the forum
Sometime i clic open and txt icone and i have a windows to paste the formula
But most of time i click open and txt icone and nothing arrive ,no place to paste the formula
Why this situation :sometime it works ,sometine no ?

Thanks

The dialog pops up only when there are no parameters in the clipboard. If nothing pops up, then the parameters stored in the clipboard have been loaded by M3D.

Ok Thanks
But a way to clear the clip board of Mandelboard when we open it
It seems basic but i don't find how

Just copy a number or something else in an edit field to make the current clipboard text invalid.

Thanks

It was working the first time i did it but since it seems not works
I have try to close the programm and reopen several times ,modifying ZStart parameter or X mid or other param,eters using number or letters
When i click after ''open'' following by ''Txt''still don't have the windows to put by paste the formula
just the invit to press calculate 3d to render 

You have to copy some letters with ctrl+c, that will put this text onto the clipboard...
guessing that you are on a windows system, else there should be some equal shortcuts for.

Thanks
I catch it now
Yes i am in windows

I hijack this thread (as usual) to say that I have released a new formula, another Barnsley commutative :dink:

I guess we can't really do serious damage to this thread  :dink:

Indeed, added too the missing sacred solid... Dodeca!...  :o (It's a bit slower than normal ones but sooo fun)

That's very cool, I was just thinking about asking you for one.  O0

(So far I had been using a pseudo one adapted from the icosahedron one)

Feel free to do a tetrahedron one as well if that's possible. (and any other non platonic polyhedra would be great also if you feel like doing it).

Cheers.

 :o :o :o Brilliant hack :beer: - That is considerably faster than my version (less flexible but faster ;) )
With scale = 2.63 both versions give almost the same results except for a rotation difference. I add this to my db also (your will be the normal entry and mine will be called "ex" )

Cool, and thanks for the compliment. ;D

Using a workaround for temporary storing space I was able to implement Manowar formula; I combined it with Phoenix formula and added a rotation. Some "liquid" effects can be achieved, I would like to see those in glass...

 :o Done a Gnarly heightfield with DIFS!!! Ty Jesse for the sample code... :angel1:

It requires a single iteration, but generates a great 3D heightfield (without a bitmap as input)! :D Itercount for Gnarl can be customized inside the formula pars, I think with the same system we can get heightfields from a lot of formulas. Less easy btw. :hurt:

Sample images from 'PolyPyraIFS'... ;)

 :w00t: :ok: :drink: :drink: :drink: :drink:

This just can't be true! Tell me I am dreaming :hmh:

It's true! you are not deaming.  ;D

Well, not true after all. :o :D :banana: :banana: :banana:

Niiiice! :surprised: :chilli:

Oh thanks friend, the sequence is...

0. Rot3D(x,y,z,0) + Shift3D(0,0,0) :dink:
1. Polyfold; pi shift seems to work way better...
theta = roundint((-atan2(x,y)+pi)/twopi*order)/order*twopi
theta = theta + shift*degtorad
x' = x cos theta - y sin theta
y' = x sin theta + y cos theta
2. Do the DE, then add something to x
3. Scale ;)

i can not find "Rot3D" in the formula lists ... do i need to update formulas ?
can you post an m3d example ?

It was an example for Knighty only, in MB you don't need this, play with each formula settings ;)

... and extending Polyfold to 3D? Folding in the same way x and z leads more or less to ... this :o :hmh: :w00t:

An alien tree-planet? Well well :alien:

??? but you are showing mandelbulber screenshots ???

No, Mandelbulb3D :yes:

Okay, here the tree planet parameter :dink:

Update the database to see the effect  ^-^

Thank you very much for the formula.  :)

And that tree planet is absolutely wonderland. ;D

It's a Barnsley-based transform, probably you can do better making it continue? With some abs() but don't know exactly how. :-\

Luca, do you think you can make a formula for those ones?

http://www.fractalforums.com/theory/mandelbrot-pearls/

No, it's not purely linear/shift/fold and I fear that it's outrageously complicated :) For now use the existing ones

Ok then, I'll wait. Thanks for the heads up.

sure, i mean t mandelbulb, i am not sure which formula package to update, i used the final.zip from your signature, and i just see 3 spheres ....

The link in his signature leads to an outdated post. Use this one: http://www.fractalforums.com/mandelbulb-3d/re-custom-formulas-and-transforms-release-t9810/

PolyFoldIFS FTW!

 :beer:

And I also tested an Amazing Box - based formula; here a render with scale = 1 (that works if you are a bit careful) :dink: Seven iterations only :o

Here I used a simple box as baseshape but any shape can be used. Box is good because it has straight edges and they look nice when projected in a sphere. (did you know?) :dink:

 :worm:  :w00t:  :worm:

Is it possible to allow pre-transforms with those dIFS in MB3D? (in a next version of course)

I second that, supercool!  O0

 :dink:

I tried to put MinR but it did not work, I am stupid :sad1: retry one day

 :banana: :banana: :banana: :worm: Yessss it works!!!!

I will allow pretransforms with the usual escapetime formulas plus dIFS afterwards, works for non-analytic formulas not really well - only a few iterations maybe:
