I doubt the framework released in stage 3 has the capacity for imaginary numbers.
Why is there a demand for fractals? You can use other software such as: http://www.apophysis.org/ to get pretty results fairly easily. Either that, or I'm not fully understanding the request. How exactly should FF handle these fractals? Maybe a mockup component would make more sense. |

if ever implemented, they would most likely be pre-defined types.....but I'm hoping for the ability to input our own formulas..... ![]()
I don't understand??? The numbers/formulas map patterns in either a 2D or 3D grid....(x,y) or (x,y,z) coordinate system.....
easily create endless complex patterns for art and textures that are either impossible or a complete nightmare to create with FF (notice what it took to try and create even a simple rudementary fractal with FF).....manipulate current noise to create all other noise patterns.....etc....
I currently use that program for atistic works.....but not easy to create patterns with it..... Vlad previously stated that he wanted to implement fractals.....but they were running into tilabilty problems with them..... Steve

steve is quite right about fractals. there are just some things that are almost impossible to do with FF. fractals is almost like the quantum theory of graphics, but its application is far more reaching than just in graphics. your cell phone wouldnt work without fractals, for instance. the antenna was derived from fractal mathematics. figuring the actual length of the distance of a coastline is a fractal problem. plants grow pretty much fractally. imagine what we could do with the creation of objects and patterns with fractals. it's actually a much broader field and has a far more reaching application in the real world than most know. programs like apophysis are cool, but quite limited to most of us, unless you've truly studied the reiterative, looping properties of fractal sets. mandlebrot was a genius and most folks thought he was kinda crazy when he started talking about fractals. lol. aint that always the way?
![]() at any rate, fractals could very easily open up a whole new world in FF and i whole-heartedly agree with steve on this one. i doubt we'll see any of it until at least ver. 3 or maybe even 4, but i think it truly belongs with FF. the potential is just too great to ignore. If wishes were horses... there'd be a whole lot of horse crap to clean up!

From your link in the first post:
Nearly all of these fractals seem to involve complex numbers, something FF doesn't handle currently (and honestly, doesn't really need to imo... using these functions in a graphics environment is already over my head). This is evidenced by the "error" seen when trying to square root a negative number, something that would typically bring results in the imaginary domain. Also keep in mind, most of the "pretty" fractals seen with colors are implementing something beyond the simpler fractal math. iirc, the colors correspond to some sort of complex probability thing, so be sure to be specific, else be disappointed when you are stuck with a black and white mandelbrot set. Getting back to a desired implementation, what would a "fractal" component look like, what would its inputs be and how might it fit into the FF workflow? Answering questions like these seem to gain a lot more validity when compared to requests that simply saying: "lets add fractals!" without any further explanation. Sqrt Neg 4.ffxml |

I don't know why FF couldn't handle complex numbers.....already doing it in component image processing.....
I don't know how Vlad would choose to implement them.....but I would guess a single fractal external input component connected to a fractal workshop/explorer environment.....where the "math" would just be proprietary to creating the fractal image for input to the filter.....and in profile gradient/greyscale color to allow colorization thru the existing color gradient components.....

When I say complex numbers I'm referring to a mathematical thing, the symbol "i" is used to represent the square root of -1.
Taking the square root of a negative number doesn't make any sense (because any negative number multiplied by itself is automatically positive) so mathematicians came up with imaginary numbers. As it turns out, they proved to be immensely important in electronics and our modern electronic world wouldn't function without using complex numbers in designing things. When you combine imaginary numbers with real numbers, you call them complex numbers. Annnyway, It sounds like you want more of an "iteration" functionality than you want a true mathematical fractal generator. I would be very surprised if nobody in this community is able to construct something that has the "branching" you desire. |

If you mean constructing, importing, and applying a tilable fractal pattern.....then yes!!! ![]() The formulas for fractals are given.....but what I think you are saying is how FF would program/set up the "generator" to create fractal images for import..... Like I said.....I would think that it would have to be a seperate environment by which to create the fractal image.....then import with a single external fractal image component..... I would be curious to hear from Vlad to how he was/is thinking about doing it??? ![]() Steve

StevieJ very beautiful and excellent examples you have put here in this thread.
What software have you used to make this nice images ? As you say it it would be really nice and wonderful to create things like this inside FF |

This thread was done already in 2010, and it seems that now is happening finally in some way, at least with mandelbrot for now, thanks mainly to Rick Duim that is developing and making fractal filters in FF
For example Mandelbrot Inside and Out |

"At least" is incorrect. FilterForge already offers iterators which gives us the ability to produce fractals. |

I am very sorry that above I said that the fractals are mainly thanks to Rick Duim, and is not true, because also CFandM have already made some awesome, very well done and beautiful Fractal filters as seen here
CFandM fractal filters for FF 4.0
Yes, you are right, I have put it wrong, as since FF 4.0 there is the loop component that offers iterations. But I think is not totally wrong, because really what I wanted to say is not that FF has the ability to make fractals, is that it can reproduce and make fractals based on already known and famous math formulaes As I know there are Sierpinski and Mandelbrot fractals in FF, but have not seen pure Flame fractals filter in FF as seen some examples above. |

Of course, it was always possible... I suspect that the speed (slow) and the difficulty in zooming in to the fractal were the main discouragements. Foolishly or not, I came up with a working but clunky UI. There has been a 2 color Mandelbrot by jitspoe available in FF since 2011. It was very preliminary, snippet like in a way and just 2 color, and the zooming needed a complete rethink, but it draws the Mandelbrot perfectly. I used the core of the LUA code and came up with the multiple offset/fine tune "bank" of sliders to deal with zooming in. Added some coloring variations and added the distance estimator method for drawing the inside of the 'Brot. The 4 different gradient drawing methods provide nice color display variations (Linear, Smooth, Steps, Banding) for more variety. So I just pulled a bunch of things together. I was the only one crazy enough to write a full blown fractal filter in FF.

I also have a 12 color Julia Set in the wings. I'm going to release it with FF 5 beta when they start accepting new filters. Don't know when that is.

Both Mandelbrots and the new Julia have been done using Lua scripting for the iterative part. Using jitspoe's 2 color versions from 2011 as the foundation. The 12 color part of the Julia is a new 12 color gradient I have developed as a snippet for FF 5.
