In all this time I have tried to find out a way to make a filter that create realistic Suds Bubbles Foam inside Filter Forge, but have not been able to do it yet, and have not found a way, is supossed that it should be possible but until now nobody else have done it yet either, although I have seen in the User gallery that it may be possible perhaps in some way

I mean to be able to do this kind of images

Here is another example but I do not want at all any kind of blur effect or out of focus as shown here

In filter forge there is this bubbles filter but these are really random bubbles that are not touching and joined tight together

I found this way from uberzev but the main problem is that ALL the stones or bubbles are EXACTLY the same size and do not have many different sizes as it happens on Suds foam bubbles as shown on the examples above

In this other filter the bubbles are also isolated and not joined together and look too much spherical and all have nearly the same size so it is not realistic

Or this other one that happens the same as the above where all the bubbles are round the same size and just slightly joined

I wonder why there is no filter that have been able to make these kind of realistic organic bubbles

The best I could do myself to get something organic like bubbles was this filter, but have problems that is too irregular and makes some empty shapes that are not at all like bubbles and more really like a tangled web

The nearest filter I made was this.
Spongiformia
I don't know if changing something in the settings it is possible to get a real bubble effect.

Yes, I agree with you, this is the closest that is from what I have shown, I love it and is an excellent filter, and is perfectly built and lovely effect, BUT it has the same problem as the other filters, that nearly all the holes or shapes have about the same regular size and there is not a big difference between the hole sizes

And this is because the Cells component is giving the effect already with all the shapes already in a regular way and all seems to be about making the same pattern

I have tried to change some of the settings and also inside the filter, but it seems that is not possible, because the problem comes from the Cells component already giving a uniform and equal based pattern

So from my point of view, maybe it would be needed to add some adittional component or compoents to the nodes of the Cells that would modify the Cells component to make it create irregular results, but do not know what would work as the only green nodes that may be useful are Noise and Roughness, so there should be something that would feed a irregular values to the Noise possibly

Here is what I have already done in my own filter to modify the Cells component, although as said, it looks much more like a wild and unexpected web than your excellent and well organized cells you have done in Spongiformia

This is the default components that are already used and available in the filter that is in the library Organic tangled web

I have tried already to use different Curve components attached to the Profile node, but until now now of the things I have tried did give any good result

I have tried also to use the Stones Component because when joined the bubbles also have straight lines but it happens the same thing, that all the results from the Stones component are very regular and uniform and around the same size of stones

Comparing this example



or this



to the result that the stone component gives below you can clearly see that the problem is the uniform result it gives compared

Although I really prefer and like really much more the more organic feeling that gives the Cells component than the stones as in the Ramlyn filter shown above



Please, does anyone know how could be modified the Cells component to make irregular non-uniform results?

Thanks very much for any possible help

You can use the Bomber in Lighten mode to create a less uniform look:

Thanks very much for your help and taking the time to suggest this, although I am sorry that I do not know how this you are showing could be used for making the bubbles examples shown.

If you put the repeat value to 3 instead of 1 it will show that most of the spheres created are nearly the same size and creates a uniform pattern, and there is no big and smnall ones, just normal ones equal in size and some small and very tiny ones, and the results keeps to be uniform.

Here is the filter made with FF 8 and shows that if repeat is not 1 then you get mostly uniform results as shown on presets.

Just found this that looks interesting and has different sizes of the holes although are not what I want but maybe could modify it in some way

Well, for realistic results, you would need to simulate a dynamic system with air pressure, surface area ect. Not really something you'd want to do in FF smile:)

What Sphinx. showed is a good starting point. Maybe try combining that with a self-scaling loop or something.

If you think about uniformity more carefully, you'll see that the sizes in Sphinx's example are perfectly non-uniform in the small scale. Of course, as you zoom out (increase the repeat), you'll see a more uniform distribution. This is to say, if you want less uniform results, you should zoom in, not out.

Using circle packing as a starting point might also work to some degree.

Well, I agree with you, that maybe FF is not the best way to do it, and maybe would be better a 3D software with physics, but yet I am still finding a way to do it in 3D software specially in Blender 3D that is free

REALISTIC BUBBLES SEEMS TO BE BASED ON VORONOI

although I have been making a research on how realistic bubbles are made and created, and they seem to be based when joined tight together like foam, in voronoi diagrams and is like the national aquatics center of Beijing that was inspired by bubbles foan

FF IS ABLE TO USE VORONOI

And FF is able to use Voronoi as it is shown for example on the Stones component that is based on the Worley Noise that is a way of Voronoi

So this is why I thought that it would be possible in FF

Because FF includes already the use of cells noise so I think it should be possible, but maybe only for regular uniform ones, and for more complex and irregular noise maybe it should be used some kind of scripting

Is also interesting this VORONOI NOISE expalanation

https://www.ronja-tutorials.com/2018/0...noise.html

Also have found this interesting Cellular Noise description and tutorial to start to understand the principles behind it

Yes it may be a good starting point and have yet to see if this could be useful and how to use it in some way. I do not know how to make a self scaling loop. Also after seeing that the bubbles are generated on voronoi, it really is not sphere based, as it has more straight lines

Yes, I agree with that I am wrong trying to zoom out as it will make it more uniform, and the good way is to zoom in, but the reason I told this is that the problem I see is that the repeat node can not be used with negative values and only is able to use integer, and the minimum value is 1, and is the default base that is given so there is no way to use the Repeat value for the zoom in, and should find a way to use the scale to zoom in

Yes, I have also been thinking about this too, and you are right that this also would be a starting point, now that there are some circle packing filters avaialble in FF, although as I have said , the voronoi is not based on circle shapes as far as I know, so maybe is not right to use circle packing

I have searched on the filter library for “cellular” for cell noise and found this awesome filter

Cellular Images by Rick Duim

https://www.filterforge.com/filters/13825.html

So I will see if with this filter can be used to make what I want as it has irregular shapes and holes of different sizes and not uniform

I can confirm that realistic organic bubbles are really possible to be made inside FF after I have just found these awesome bubbles created by Martin Naumann shown in his gallery here

This example shows exactly what I was trying to tell and explain about irregular shapes and avoid uniformity and have much difference in size between the bubbles and have some huge and some small ones

https://www.filterforge.com/forum/read...&TID=14616

Although it is not available the filter to use this, and will see how this can be done in some way
