it says MMFWip3dNew is needed sad

and if no one says a word against it, i would like to close this thread, because
it had a main theme, and now it is diverging again into detail questions on implementation
but it is no more affecting the original thread theme police police police

I would just like to say - before this is closed - that MMFWip3dNew must have been what it was called on David's computer; but using the current one, "MMFWip3d", which is linked to at the top of this thread, works just fine.  smiley

Someday, man will understand primary theory; how every aspect of our universe has come about. Then we will describe all of physics, build a complete understanding of genetic engineering, catalog all planets, and find intelligent life. And then we'll just puzzle over fractals for eternity.

That's correct - when UF complains just select the wip3D5 formula from MMFwip3D.ufm.
My apologies for forgetting to do so prior to posting the UPR.

alright, please stop posting here, and make up a new thread for asking questions on usage of the formula

@Tglad, many thanks for showing us this incredible fractal formula. You had very good idea with folding function. I have just rendered some cubes and tried to flight inside. Interior is really beautiful!!!
For rendering I used my delta DE algorithm. I'm surprised that it works well with this very not-lineal function.

scale = 2

I'm preparing to render some flight animation through these endless tunnels (It will take about 100 hours smiley )

just stunning cheesy
I love how pretty organic values come to quite "pure" shapes in this kind of fractal.
I wonder if you could derive a building-generator from the formula smiley

Nice render. Its interesting how clean parts can get interrupted by more chaotic areas, that look like its crumbling away. You get the same thing on the other folding conformal fractal here http://www.fractalforums.com/3d-fractal-generation/continuous-conformal-mandelbrots/.
Kram, it would be cool if someone worked out how to control all these fractals go make a landscape (+ buildings) as they wish... then leave all the finer detail to fractals. I guess there are some tools that do stuff like that.. at least generating random landscapes with trees and rivers.

Anyhow I'll put this and some other interior shots into a new post... so its better named as trifox pointed out.

David (or anyone who knows) do you know how I could try out a new colouring scheme? The scheme I would like to try is below, I think it might give more precise colouring. I can't see quite how to add this into the UF code though. Thanks for any help!

; initialise before iterating
colourScale = 1
totalColour = black

; each iteration choose colour based on the choice of folds for that position
int numOutside = 0
if x>1 || x<-1
 numOutside = numOutside+1
endif
if y>1 || y<-1
 numOutside = numOutside+1
endif
if z>1 ||  z<-1
 numOutside = numOutside+1
endif
if numOutside==3
  colour = red
elseif numOutside==2
  colour = blue
elseif numOutside==1
  colour = green
else
  float lengthSqr = MagnitudeSquared()
  if lengthSqr < minRadiusSqr
    colour = yellow
  elseif lengthSqr < fixedRadiusSqr
    colour = brown
  else
    colour = purple
  endif
endif
; reduce the amount geometrically each iteration, so each point converges on an exact colour
colourScale = colourScale*0.5
; accumulate the colour so each iteration we mix in a small amount of the new colour
totalColour = totalColour + colourScale*colour

Have now added a colouring option based on the "genetics", though at the moment it isn't using colours directly:

An extra "Lighting + Orbits" colouring method is now available in the updated mmfwip3d formula (wip3D5).
This allows full-3D based orbit trapping for any of the formula types plus the option of using "genetics" based colouring for the "Lowe's Mandelbox" and "Simple Sierps" formulas.
