How to create this image

sorry.. no image attached here it goes

Yes, you can make it, or something very similar, with multiple instances of bomber and threshold. Probably with Loop as well, but that can get tricky.

Basically you need to make a square with one half filled triangle, the other half see-through plus the lines and dots in the corners, then use a source image for the Bomber chance input.

Start with the smallest triangles and work up from there, increasing the size to double on each consecutive round, whether manually constructed or with a loop. For the lighter areas (smallest triangles), use a high threshold and for the larger triangles a lower threshold -- or maybe it is the other way round -- anyways, so that the darker areas get the large triangles in the end. Looks like there are about ten different sizes there.

As the triangles get smaller, the line weight needs to stay consistent. Easiest approach is to construct the triangles for different sizes individually, but it can be done as part of a Loop, if one feels adventurous. Then there is the matter of rotating the triangles in four different directions. Can be done several different ways, Rotate component being the easiest.

We might as well demo it for you haha.

I guess it isn't quite as simple as I thought...

My first attempt with lifesaver, barely recognizable. Needs a more intelligent way to select where triangles fall, or which way they are rotated.

beto33 It was done in processing

Please, Can you give the link to the processing page where this effect is shown?

I have tried to make a Google images Reverse search to see if this images could be found but I could not find the source of it

This is not what you want, but I was tempted to see what one bomber could do if I was extremely careful on placement, for what it's worth:

More refinement. This is with one bomber. I'll come back in a day or 2 with a multiple bomber version, which may do the trick (fingers crossed):

Last test. This is a 4 bomber version of the lifesaver. Any comments?

Thanks Skybase's idea of mask-blending via threshold was exactly how I did it. Each bomber has a different threshold (into bomber opacity) and a different pattern, denser patterns are in the bright areas. Surprisingly medium speed, considering the 4 bombers & a blur (36 seconds for 600x600 example above on my MacBook Pro). So much for the geek talk.

I will refine this and probably release it at some point. Any other comments or requests for this filter are welcome. This filter has a community feel, without your comment I would have never thought of doing it.

WOW!! WOW!! love really very much all your examples you have put Rick Duim, they are beautiful and interesting, well done, if you want, it would be good that you could publish them in the FF library, as although is not the same effect as the first post, surely gives a very good and artistic effect unique and not seen over the more than 11150 filters available.

Thanks all. Community filter, everybody threw their 2 cents in, I was the blender... Not like the original processed image, doing it that way seems more like a map script, the triangles in that one appear to be drawn off a grid, "growing" and dividing away from the grid based on image brightness. Also bomber limitations (no particles outside of the 0,0 to 1,1 particle space) dictated some design decisions.

YES! I remembered that something done before could adapt to the main part of the image but could not know which filter was, and now you Kraellin has found it

Is true that maybe this adaptative could be used for this effect, although really do not know as I am not an expert in FF to know if it may work or not

Adaptive Tiling made by byRo

and also maybe

Adaptive Dots by Oolfanska

A few thoughts on some different approaches: (I don't have FF in front of me ... but I'll try to implement them later tonight, maybe.)


A) You could create 4 thresholds of latticework, 1 for each scale. Then add them w/ screen in a big stack. This would help get reduce the linework being split at the gridlines.

B) Could rotate the input image 45 degrees, and then use the regular grid tools. Then rotate back to square.

C) Could use 'max' node to create more consistent linework.

D) Use zoom. (That's how the cutline* filter works.) You zoom in and out to scale the pattern.


E) This problem actually reminds me of Wang Tiles a little bit.

Missed your question SpaceRay. The image you showed is a one bomber version, the smaller triangles are generated by the bomber (but as you see, they are smaller lines and fade). I probably have that one laying around, or could reproduce it. But I really did not like it.

And the same filter, using a diamond pattern. Will update this version tomorrow to allow turning the diamond pattern on or off for each bomber.

well, You may not like it, but I think is very good and cool, and a good and interesting variation

Here is more of a "lattice" style look at this. 4 bombers, each with twice as many rows as the previous one with the same simple triangle. Have not adjusted the line width, not sure which way to go on that.

WOW! Like much this one you have done, love how complex the lines are made and beautifully

I am working on Triangulation 3. The last picture that SpaceRay put up will be possible with the filter when I release it. Currently it does not do what the picture shows, that was an intermediate test, but I am going to work on it tonight and put that particular "feature" back in the filter (making the lines smaller as the triangles get smaller).

One more for the evening from Triangulation 3:

Dear Rick
every variation creates stunning patterns.
I hope you soon upload the finished filter. Congratulations!!
