the last formulas today  seems to work well on a test or two it's ok (I'm not sure)
Thank you again and thank you for being with us for new formulas

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

 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

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! :smiley
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 ... evil

 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!

 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
