Nice Reaction Diffusion patterns with Filter Forge and also Photoshop

Little did I know I was involving Kiko in such a hilarious (yet sinister) scientific experiment. As far as I can tell the experiment was flawed... the box was always open...

In the first post I have put the awesome and amazing ferrofluid colorful artworks of Fabian Oefner BUT did not know how it was done really, and how can he get this colorful patterns, and I have found a video that shows it

See it here

Ferrofluid magnetic paintings with watercolors Showing in video how is done

It makes also reference to this other one where Fabian Oefner is interviewed and asked how he makes it

fabian Oefner blows our minds with these artworks

And with large and big images is also his well done article

FF FILTER SIMULATING THIS COULD BE POSSIBLE IN SOME WAY?

There is still not a FF filter that can simualte this effect, I mean have these kind of black patterns with colors fiilling exactly the internal parts, And maybe it would be difficult to make as I do not really if you can define to fill specifically determined areas in FF, and there can be additional problems to make it possible

My thoughts exactly. Diffusion is not for FF. As Skybase noted, it makes more sense to actually do it "for real". Even to go past reaction diffusion with Photoshop or to write your own program, to really get the look would require an understanding of magnetism and fluid dynamics (and the insane formulas that go with it). The only fluid dynamics I know about is my morning cup of coffee

My suggestion is ONLY about creating a black and white reaction diffusion pattern and fill the closed parts with specific colors or taken from a source image. The difficult part I see is that the one color have to fill only one part and then in another there should be another color, so the inside of the closed can have each one a different color

This is also one of the reasons why I'm suggesting you should do this outside of the program.

I noted how the program doesn't like iterating stuff as much. This is exactly the issue you see in the screenshot above.

When I made that network in Nodewerk, the way it filled those gaps was complete brute force. For each iteration, the xy coordinates of the fill node are randomized as well as it's color. Each fill is remembered and fed back into the loop for another area to be filled at random. There's no way to check to see if the area's already filled or not filled. The end result is a very rough, crude method that works for relatively small images but for large images takes another thousand iterations. Basically, it's a really dumb method of filling in each and every area. Imagine throwing paint balls into buckets blind folded. That's what I'm doing there.

FilterForge doesn't have a "flood fill" node by default and judging by the nature of the program, it never seemed like something that's possible at this point in time. Although I never know what other users come up next.

Flood fill would be a completely different subject.

I kinda feel bad for misinterpreting your post, but I also have to say that your post reads like you wanted the effect. That being said, this thread is entirely about making that effect happen. Besides, if you ever want to make something of that level, you'll still need to find a way to simulate it anyway.

Perhaps you fine people would like to take a look at my color-enabled diffusion reaction Filter Forge filter?

Ramlyn has made an awesome and excellent work using the Reaction difussion in filter forge and want to add it to this thread as it deserves to be seen more and not get lost in the ocean of FF filters

and also show here the great and well done examples made by DJI showing what can be done

Some reaction diffusion experiments I've done in FF.

Here also I have found this cool and great animated version of Reaction Diffusion made with generative software

Or also you can use the FF created reaction diffusion created works and then use it for 3D extrusion or bump mapped
