Well the pictures of the presets look cool.....This one killed my computer...lol.....Froze before it even started to render....Tried it three times and struggled to copy the xml to a place where it was safe to edit to check out that way...A lot going on in this one....

Thanks Boogie Jack and CFandM! It works for me on my Mac and Windows systems with the latest OS (OSX and Windows 10). On the Mac when I developed it the system would slow down like it was leaking memory, but only a guess. Both systems have 16GB memory. Have you contacted support?

Great to see that you have made this available and is really great and well done

I have just made a first test and think this is really interesting and awesome how is done and gives really perfect and amazing realistic koch f actal that fractals that are usually done using complex math formulaes and Rachel Duim have done it without them in a clever and expert way and including optional color

I have made a 2048 x 2048 test and it looks very good and it needs to be higher resolution to be able to see really all the beauty this can make

I have seen this is based on a star , and I think this has a high potential for possible variations and make other different options and be able to experiment with other tings

Congratulations for making ths without using any math or any complex fractal software, and just using your expert knowledge of FF

This is a beautiful filter, but something seems to be making problems. When I downloaded it Filter Forge froze and I had to use the Task Manager (Windows 10) to close it down. When I restarted FilterForge it initially worked but froze again as soon as I searched for "Koch Snowflakes". I saw the filter in the search results but wasn't able to click on it because the program was frozen. After shutting down FF with the task manager again and restarting I was finally able to load the filter and have had no problems since. I never experienced anything like this with FF before. Maybe it has nothing to do with the filter, but it is an odd coincidence that CFandM also had problems with it. Since it's working now (and makes beautiful patterns!) there is no reason for me to contact support.

Thank you, Rachel Duim for the lovely filter!

Thanks EAdams and Ramlyn!! -) -) Instead of using loops I used "stacked" groups, where the same group calls itself, kind of ersatz recursion.

Going a little further with the filter, here's a 2048x2048 with a detail of the center.

Yes, This is really awesome example result, and it looks very good

You had the same idea as me, as I thought that this could be developed further using source images, and also would be cool having a scale and offset to be able to optionally show the part of the result that you may want in more details and zoom in the amazing creation you have done

POLYGON DIFFERENT SHAPES?

I have seen that the base seed is a 5 point star, but I think that you could add a slider to the SIDES of the polygon component and so be able to choose the seed shape that you may want, either triangle, square, pentagon, circle....

And also add a checkbox to choose star or not

It is interesting. Will require a little more thinking. The version above just uses the center of all 7 builtin preview images to fill the hexagons (not a seed, just a crop). I started putting offsets in to try it out, doesn't work that great. So I may convert over to a hexagonal seed. As for other than 6 sided... there is always more experimentation. Here is 1 image thrown at it...

Here's an example with a triangular seed. Looks great but... slow, 6 1/2 minutes for 600x600. And as other have noted, getting less stable the more I work on it... rarely have I ever crashed the Mac OS... but did it today.

Thanks! And a lesson learned, this filter is a memory hog, it uses gigabytes of memory sometimes, I was watching the performance. This is even more so for Koch Crystals. For fun watch in the Task Manager (Windows) or top from the command line in the terminal on the Mac. I have crashed the program in both Mac and Windows numerous times. I have taken down the OS on both sides as well. No other filter uses as much memory as the 2 Koch filters.

First time when i download this filter today i got similar problem what described in above: was eat all my 16gb of memory and comp is freeze. I barely managed to kill the process via the taskbar heh.
But when i tried to render it again it goes smooth and with about 2-3gb of memory, thanks god. Just i already thought that it was properly behavior and appears filters which require more than 16gb memory damn lol.
But, i think dev's should pay attention at this issue.

In FF10 there is a new component that will speed up Koch Crystals by a factor of 3 or 4. So the devs have been paying attention... I will take a quick look again at Koch Snowflakes to see if I can speed it up somehow.

Thanks, merci Ghislaine!

In FF10 I will update this with a slightly faster and more stable version using the new bitmap cache.

It could maybe be possible and interesting to make another version of the filter mixing the result of this filter 6 times, one in each hole of the arms of the main snowflake, so then you could have a big texture pattern made from all these beautiful and awesome koch snowflakes

Will make it and show it if could be maybe interesting and useful
