IMPORTANT. HOW TO USE TRANSFORMS AS PRE-TRANSFORMS
Jesse revealed me this trick that I didn't know. It is really really useful if you like to use transformations as pre-transformations.
It is fundamental. Why?
For example, the inversion of an inversion returns tre undeformed pixel ... So you will never want to do inversions more than once. :D
Apply the same Mobius transform twice will give another Mobius transform, but it is unwanted! This will cause a slowdown of the computation for nothing. (Note that I said "the same". Mobius conditional transforms are a completely different thing ;) )
The same applies for every possible coordinate transform (except for coord - scaling- inverse coord sequence that can give interesting effects, a "particular case").
In this mode you can do (for example) a Mobius transformation only once. This will reduce a lot the DE disturbing effect, keeping the deformation effect at 100% of its strength.
It is easy as drink water. Put the transform, or all the sequence of wanted transforms, at FIRST. Then put every formula that you like, after all the transforms.
Now, go to the first formula (for example it's in tab named "Fo.2"). Check "Repeat from here".
This allows you to calculate every IFS or Julia fractal in transformed coordinate mode.
To do the same with Mset fractals, you need a complete coordinate inversion. For now only "SphereInvC" is a complete coordinate inversion. Expect more soon. :D

Example of a Julia set deformed by a loxodromic Mobius transform

I continue here my releases, to not overwhelm :hmh: the 1st post :tease:

24.0
Added an alternate commutative Barnsley. (nobody will use it but who cares? :evil1: Merry xmas :-* )
24.1
Corrected a mistake in coding IQ-bulb, so it looks much more consistent with the "original", :D kept the old one but renamed
24.2
General; generalization and unification of all (or almost all) the possible bulb funcs in just one formula. Phew! This was NOT not easy but wow, a bunch of crazy things are possible now!!!
24.25
General; Adjusted, because 'recipe 2' did not take into account 'zmul' :embarrass:
24.28
Added to my collection _QuadrayTransform2.m3f - Jesse forgot to include it in latest release and it just disappeared from the whole internet so here it is now! :dink: Thanks to Lenord for giving it back! ( I lost it too!  :sad1: )
24.3
_QuadrayTransform2 + added Scale for negative Quadray coords
24.4
MandelView (Thanks David Makin)
24.5
_GenCWarp (Thanks Aexion, Jesse and ... basically everybody ;D )
24.6
_GenCWarp Added two controls to adjust the strength of the effect and/or mix C with xyz. :dink:
24.7
Quintic a wiki-fractal :o ^-^ and a half-octahedron, hacky KIFS formula
24.8
Makin3D collection (1 to 4) now you can explore even more Makin stuff with your fave renderer :dink:
24.85
Makin-NSR-tri added (by the master's request :beer: )
24.9
BulboxP-2 added. This formula has a strange behavior, but in some condition can be so fun! Too bad needs a very low raystep/stepwidth to work good. :'(
25.0
GenCWarp fixed a bug: now value 0 for Theta-Args is correctly handled. (No more glitches. You will still see glitches if you try to choose a value out of range, and it will not be fixed btw :police:)
_DEComb_ISph_Plane added
25.1
OctKoch added (uncertain about something. but it's flexible so I added btw) :o ;D
25.2
DodecahedronIFS (one of the basic Sierpinski solids, it was missing for some reason) added :beer:
Changed default scale to 2.63 - some details look way better
25.3
Faster version by Blob added (hack from Jesse's Icosa)
25.4
ManowarBulb added :beer: - requires SSE2 but it only uses the register for storing, it's a bit slow because it does a float exponentiation btw
25.5
GnarlyIFS added :beer:  - requires SSE2 too because it's derived from waveIFS...
25.6
DucksIFS added :beer:  - requires SSE2 too because it's derived from waveIFS... And it's very slow, because it needs many iterations and a complicated magnitude evaluation to show up a good detail level.
25.7
Some useless stuff added... Sorry... :) Another Beth thingy and a variant of quat
25.8
Amazing Surf added. (by Kali) implemented by me of course :tongue1:
25.9
Torus and Knots added. (Both for dIFS) :D Hard enough to do those!
26.0 (Both for dIFS)
Torus updated with aspect ratio.
More funny shapes; TorusEllip + Pyram
26.1 (Both for dIFS)
PolyPyra added (flexible shape, can be used for many solids)
26.2 (Both for dIFS)
PolyPyra - added Star slider! Perfect for Christmas scenes :angel1: :angel1: :angel1:
26.3 (for dIFS)
PolyFoldIFS added!
26.4 (for dIFS)
PolyFoldExIFS added! (Has a 3D z-fold included - it's slower but more powerful)
26.5 (for dIFS)
AmazingIFS added! (be careful, use few iters or your computer will melt :D )
26.6
Knots2 added. Ported from Knighty's formula! Many more figures are possible ;D :surf:
26.7
KleinBotT added. Another Klein bottle too added... :D :dink:
26.8
Added misc surfaces, some so funny...
DecoCube,QCyl,Umbrella,Quadrics
26.9
Added misc surfaces, some so funny...
Scarab, Piriform, RiemSqrt plus patched/improved existing ones
27.0
Added a new transform foldingoctIFS
27.1
Added a new transform cayley2IFS
27.2
Added new transforms, and FoldingInfy (continuous eqv. of tiling) plus the most irritating shape ever; Pen-Ngon :hmh:
27.3
Comma shape + added an useful option to Quadrics
27.4
foldcut shapes added, based on amazing Knighty scripts :worm: plus some sphere playaround :dink:
Fixed Comma because it did not worked well... Don't know why. But ok ::)
27.5
Added a test version of Apollo 3D
27.6
Added sliceIFS  :D
27.7
Improved sliceIFS + added sliceExIFS + loxodromeIFS :worm:
27.8
Latest version of all my formulas + extras ;D ... see the file
27.9
Added more misc isosurfaces. Citrus, Mitre, Cayley surface, Pseudosphere, Dini. The last two are my favourite, too bad Dini is very slow btw :-\
28.0
Removed Citrus for now (it is very buggy... I will replace it with a similar thingy) but added Devil (devil =  :fiery: ) ;D and bugfixed Mitre (produced some unwanted "spaghetti" on high iters :angry: now they are a lot thinner so they will not disturb ;) )
28.1
Added some surfaces. But they cause bugs on high iters; Limpet
DecoCube fixed, plus some bonus wavesp, weirdcube, toupie (it seems to work on higher iters)
28.2
Fixed some DEs and added again that Citrus :yes:
28.3
Added boardIFS (for chess estimators  :D ) and SchwartzIFS surfaces
28.4
Added YinYangIFS + Loxodrome2IFS :D
28.5
Updated with some stuff ... :D
28.6
Added trans-qIFS :D
28.7
Made ex versions of 4D ifs like Menger, Sierpinski and MixPinski :D
28.8
Made _Translate + _Rotate "random" transforms :D
28.9 ... until 29.0
_Rotate "random" transform "fixed" - now works really as expected also with ABox. Increased max range to +-2
29.1
Tried to add a MinR thingy to AmazingIFS, don't know if it's the real thing forgive me :embarrass:
29.2
Fixed - now works as expected :beer:
29.3
_asdamTrans added :beer:
29.4
_CondLyapunov added :beer:
29.5
A full set of itercount modifiers added. They are of two kinds.
Lyapunov type;
The itercount of the formulas is modified following a binary string rule. The itercount will be set 0 / 1 in simple Lyapunov switch or to two different values in the general Lyapunov.
Generic switch;
More advanced.
The itercount will be set to three different values according to a critical iteration value. This can give very unique fractal shapes. It is not easy to explain here... But believe me :police:
3 formulas added :beer:
29.6
Fixed _sphereinv for the n-th time again to avoid navi issues :embarrass:
30.0
Extra formula; ABoxMod2! :police:
29.7
Fixed _sphereinv for the n-th time again... Sick and tired. But this was a minor issue btw.
29.8
ducksIFS added angle option, very reccomended to play with that setting :D
Added also missing COLOR option
29.9
Added a new HeightMap and updated other stuff O0
30.0
GnarlyIFS added color option, and 2 more gnarlyIFS!!! :D
30.1
GnarlyIFS minor bugfixes, + added more formulas like a standalone dodeca-folding. That Jesse never did for some reason? :dink:
30.2
SierpinskiFull ; full tetrahedral symmetry Sierpinski. Jesse's was not fully symmetrical. :) In fact this works more like normal KIFS like Menger3 and Icosahedron.
30.3
SierpinskiFull added SierpHilbert style edges; disabled by default.
30.4
Reciprocal x,y,z 3 added - continuous functions so they work a lot better without DE trouble
30.5
BUGFIX ATTEMPT on RotateRnd, TranslateRnd!
Now they seem to work
30.6
Added GearIfs
30.7
ABoxMod1 DEfix!
30.8
room DIFS good for color fooling ;D
30.9
Added Gear2Ifs inspired from Incendia :dink:
31.0

31.1
Added SphCageIfs "sphere made of rings" ;D
31.2
Update & optimization for SphCageIfs
31.3 and .4
Added cubetubeIfs + UPDATED
31.5
Added tube versions of all platonic solids; Cube, Tetrahedron, Icosahedron.  :horsie:
31.6
Replaced Icosa default param to plot a dodecahedron not a truncated solid :tongue1:
31.7
Added columnsIFS :D
31.8
Added options for style in columnsIFS :D
31.81
More fix in columnsIFS (to allow more styles)
31.9
Homemade optimization, applied to all gnarly and to ducks IFS to get a 5x speedup!
32.0
Added a component to optimization to get a perfect result. :beer:
32.1
HeightMap2 now gets a "perfect" DE.
32.2
RoomDoorsIFS added after 3 days of work
32.3
ABoxPlatinum added. Loads of features.
32.4
ABoxPlatinum - a little 'bug' in rotatable folds was fixed, but left also the old version. :beer:
33.0 After a long pause! :dink:
Reciprocal x,y,z 3b added - more customizable recips
33.1
Cantor, Octafull added
33.2
koch_oct added
33.3
Menger1-IFS added (Menger transform just for DIFS!)
33.4
JCube3 - approximation made by Knighty. It is an APPROXIMATION so take it as is. :) Just don't pretend flawless details
Added also _YplusSinZ2
33.5
_invcylindrical optimized - speedup :dink:
33.6
I spotted a fantastic hex-grid formula and added it
http://k3dsurf.s4.bizhat.com/k3dsurf-ftopic133-0-asc-30.html
hextgridIFS
33.6
hextgrid2IFS - more classic tubey work. ^-^ formula by abdelhamid...

34.0
New year 2013 special! A fistful of variations of tri&hextgrid added! :drink:
34.1
More hexagonal madness!
34.2
Improved a lot hextgrid3IFS & hexgridIFS following Knighty's concepts and scripts, now they have a lot of added functionality and possibilities for new shapes :beer:

Title: Re: Custom formulas & transforms - Release
Post by: skyzyk on January 29, 2012, 04:21:14 PM
Luca the numbers went from 26.5 to 25.6. That is where the numbers are not correct. I am talking about the version numbers. It doesn't really make a difference to me because what's inside is the most important. I just thought you would like to know. I hope you understand me better. Ciao bello.

PolyFoldExIFS added! (Has a 3D z-fold included - it's slower but more powerful)
26.5 (for dIFS)
AmazingIFS added! (be careful, use few iters or your computer will melt cheesy )
25.6
Knots2 added. Ported from Knighty's formula! Many more figures are possible grin surfing
25.7
KleinBotT added. Another Klein bottle too added... cheesy wink
25.8
Added misc surfaces, some so funny...
DecoCube,QCyl,Umbrella,Quadrics

Do not know try again (the server may have some weak moments? :-\ )

ericr; I perfectly know this. Mobius transforms in 2D are very complicated. In 3D are far too much for me for now so nope! :hmh: :death:

Do you mean; intersection and stuff?

Yes, I think it is actually possible (at least intersection is very interesting and possible). Probably in the future (for simple shapes + slices)? :dink: :beer:

Now finally AmazingIFS has MinR setting, only you have to use 1/minr instead of plain minr ;D


Title: Re: Custom formulas & transforms - Release
Post by: ericr on March 23, 2012, 02:58:29 PM
 I have send a private message but it did not work
So that is the question
how work  MobiusTpx if you wound
what are good parameters for a suitable result
on the net It is nothing at all in 3D only in  3D
Thank you in advance and thank you for all
ERICR


Title: Re: Custom formulas & transforms - Release
Post by: DarkBeam on March 25, 2012, 10:53:36 AM
Mobius transform is;

z' = (a z + b) / (c z + d)

It depends on what you want to do, try various values remembering that results are very odd and iterating it leads to nothing most of the time! ::)
Normally it's good to have cabs(a) = cabs(b) = cabs(c) = cabs(d) = 1 (no zooms)
Examples
a = 1, b=1, c=(0,1,0), d=1
a = 1, b=1, c=(0,0,1), d=1
a = -1, b=(0,1,0), c=(sqrt(2),sqrt(2),0), d=1

... etc ... :evil1:

Post by: ericr on March 25, 2012, 11:21:18 AM
 I think I have found a way to Mobius IT CAN BE USED to make fractals like Indra's Pearls with symmetric matrices coefcients to see examples
but how do I book further ller shall cost me 90 euros in French
but see for yourself

You are not using formulas correctly; Mobius can not be used alone, and does not affect difs!


Title: Re: Custom formulas & transforms - Release
Post by: ericr on March 25, 2012, 12:39:34 PM
 ok so it would take a mobius transformation of "special" for DIFS
but if what I did wrong so why is it changes forms based on parameterized I try and fractal change shape?

"Change form" without seeing any shape is not enough, a fractal formula must show a shape to be called fractal formula. An unconditional mobius transform alone is simply not enough. That's it!

There is something i really don't understand  about all the "custom formulas":

why they have exactly the same name and file size of the formula already included ?

So are the same of what already included or not ??


and if not why use the identical names ?

May sound a dumb question but i am really puzzled

Post by: Jesse on April 29, 2012, 12:38:08 AM
Just tried it, it seems that the AboxSmoothFold formula got issues if the MinR value becomes 1 or higher.

Maybe division through zero or sqrt from a negative number... dunno, have not looked at the source code.

Keep it below, than it works!  ^-^

I have been using FreeFileSync (http://freefilesync.sourceforge.net/) to see which files change on each update.
I compare the unzipped new fmlas.zip folder to my existing MB3D formula folder.
I hope this can be useful to others.

Update: I would no longer recommend FreeFileSync beyond version 6.2 due to a bug in later versions and reports of bundled unwanted software in the download from sourceforge.
FreeFileSync Portable 6.2 (http://portableapps.com/apps/utilities/freefilesync-portable)

Hi Luca, Just a wee request; I've found your 'SphereHeightMapIFS' formula very useful
in creating apparently complex and 'techie' looking objects. I wonder how much work would be
involved in producing other heightmapped dIFS? Cube, Cylinder, Torus etc would be great,
especially if Jesse implements the extra slot/s for dIFS in DEcombinate in some future release. :yes:
As ever, I live in hope!!  :dink:


Title: Re: Custom formulas & transforms - Release
Post by: Jesse on October 02, 2012, 03:13:41 PM
It is not very complicated, though even for me much time consuming...
made a cylinder heightmap formula!

Luca seems to be long time absent, hope he is doing fine!

Greets,
j


ps: put the formula in there so it is visible for everyone:

Realy writing a formula is pretty hard and time consuming thing. Even if there are built in compiller like in UF and used formula are short, if you want your formula would be good one, you 'll have to code it and then test, and then rewrite the code and then test, and then modifie so that default settings would have stable good result and then write some hints. And here alsou one should not only to compile, but alsou to hack the code. And here are pretty many formulas. In UF there alsou are many formulas, but most of them are trash, say I realised that there arn't so many good implementations of kaliset;)
One of the most fun feature of M3D is hybridisation, and without content, you woun't have much to hybridise;)

Realy great job is done :beer:

AboxPlatinium have everything. Could be that you alredy noticed (or that alredy are somewhere), but you can parameterise boxfold lenght. If lenght is some 0.1 it getts enought differen to be interesting. I found this in M Benessi version of mandelbox. Just to notice;)

if (zx > check)
{
zx=Fold - zx;
}
else if (zx < -check)
{
zx=-Fold-zx;
}

Throught anyway, this is very simple, maybe this alredy are in some of many abox formulas  :hurt:

CrossBiFold is in Mandelbulb3Dv182.zip (http://www.fractalforums.com/index.php?action=downloads;sa=downfile&id=43)
Latest "new fmlas.zip" has 117 formulas/transforms compared to 348 in the Mandelbulb3Dv182 M3Formulas folder.
