WHAT I LIKE

Apart from previous post

1 - I like the way you can choose to make the sierpinsky in 5 layers and sel ect what parts you want to use, and additionally with the Max Depth that replaces the central triangle with another sierpinsky triangle inside that is a good idea.

2 - Like much the option to have the Tri-Parallel-Hex options so this way, not only you can do a triangle, you can also make a double triangle making a rhomboid and then making the Hexagon tiling

3 - As in other filters, it uses the well done and easy to use SEED view to create your own seed for the tiling of the triangles

4 - Like Preset 8 how is done with the missing central triangle,, and making three fractal frame style.

WHAT I DO NOT LIKE

5 - Although I have some things that I do not like as much, Maybe I think that the main big background triangle (Layer 1 checkbox) has maybe a bigger size in comparison with the other triangles, and think that depending of the source image, it may sometimes look wrong. Will have to make more tests.

6 - From the tests I have done, I think that it would be really good if there could be an option to have the edges of the triangles visible and have a little width, so you could then clearly see optionally if wanted, wh ere each of the triangles are and the size of each one.

7 - From my personal point of view I think there may be missing perhaps and additional iteration and have also optionally the layer 6 with the smaller triangles filling the remaining space that is visible of the Layer 1.

I think that maybe you did not add the layer 6, so it could be shown better the bakground of layer 1 and could not be needed, but as it is optional and is a Sierpinsky fractal it could be interesting to have it, or maybe I am wrong and it may not look good, do not know.

I tried to make it myself but still do not understand how it works, and do not know how easy or difficult this layer 6 can be.

Sorry about Point 6 that I thought it was easier, so for the edges of the triangles is not as easy as I thought because when you add the edges to the main triangle created first, it will be scaled down for the all the other smaller triangles and so it will be shown with a smaller edge and so it is wrong

And also that is needed to scale the triangle to be shown fully

If what you want is to be able to identify and see clearly the triangles that builds the lovely sierpinsky fractal and not just the pure tiling, it may be difficult sometimes as they get mixed as shown here

I agree with most of your comments. Here is a sample of an updated filter, has to be a new filter, 3 more controls. First a sample...

Here is the filter I have made

Sierpinsky Crystals additional edges right.ffxml

My own version uploaded above I think is not working correctly as the edges may not always work right and I think needs more work

The two images shown here above about the edges are saved as the last 2 presets in the filter uploaded

Hello, Glad that you agree and like my comments and is a good news that you may be doing and updated version with more things.

Thanks very much for showing your own version and will see how it works

I still have to finish my own version of the Sierpinsky triangle that is different to yours and have 5 different colors and it has not the tiling of the images inside the triangles.

I have seen that in the filter above it was wrong because it was badly positioned the edges over each triangle and so it was looking not good.

But after making it right, I made many tests and have not been able to make it possible to manage that just one slider with remapping can give different edge sizes, so I have decided to give a individual separate slider for each edge so you can decide how much of an edge you want for each layer and have it all the same equal or different

I have put it in the first presets to see the difference

Sierpinsky Crystals Individual Edges.ffxml

here is the same without the edges

Here's a sample of Sierpinsky Crystals with background color, edge color and 6th layer. In the queue. The first 4 layers have the same edge size now. Not practical to go below that level.

LATEST: the filter is updated. I found a couple of minor math errors, so another update...

Before you have made the update with the 6th layer, I already have found the way to make additional layers and I now I have got the filter with 6 layers, 7 layers, 8 layers and 9 layers but the result makes not possible to update it in just one filter because it becomes much slower, so it should be in different versions

As you have done an awesome work making this sierpinski triangle in an amazing artistic way that nobody else have thought ( I have seen lots of different ones) and so I want to be able to have it all the possible iterations that can be visible

As you have done a great work in the way that you can be able to select how much layers you want to use and is optional and see easily what looks best.

Here is an example with 8 iterations that you can see at full size all the details with 8 layers, it may be less elegant and more tight and not as nice but is the full fractal.

Very nice. The reason I did not go any deeper than 6 is illustrated in your tests. I normally won't release anything that is over 2 minutes at 600x600. But for a particular look, you can go deeper. I appreciate that the method I used is different than others you have seen... ironically I did not look at a lot of examples and just used my tiling method that has served me so well.

UPDATE: added a couple of cropping rectangles, now twice as fast or better. Coded it too quickly, hopefully this is the last update

The 27 sept update is really amazing, impressive and great how you have been able to make it much faster, is not twice as fast, is about triple as fast and sometimes even more!!!!! Congratulations!

Please, would be possible to know what you have changed and optimized to be able to get it much faster? only if it is easy to explain

1- First Version original with 5 layers No edges

1.1 - Preset 2 and 8.................6.75 seconds
1.2 - Preset 6...........................5.29
1.3 - Preset 6 + Max Depth......7.84
1.4 - Preset 4 Hexagon............8.60

2 - Second Version - 6 Layers with Edges

Preset 3 equals to Preset 2
Preset 7 equals to Preset 6
Preset 5 equals to Preset 4

2.1 - Preset 3...........................15.14
2.2 - Preset 7...........................24.10
2.3 - Preset 7 + Max Depth......49.01
2.4 - Preset 5 Hexagon...........50.43

3 - Third Version faster - 6 Layers with Edges

3.1 - Preset 3............................5.27
3.2 - Preset 7............................8.90
3.3 - Preset 7 + Max Depth.....12.41
3.4 - Preset 5 Hexagon...........17.03
3.5 - Preset 5 Hexagon 5 layers 8.98 seconds equals to 1.4 above that is 8.60

and it does not slow down the filter as the 600x600 version takes 25.60 seconds

here is the filter for you to test it yourself with the 4th option in the slider, sel ect "Patern" I could not fit the double t

I only added 6 components that I have separated below the filter with a note

It is made from your latest 27 sept version with all your own presets, so you can test how it looks the pattern of any of your presets selecting the 4th option

the above example is the added as a preset, although the above one is cropped

I changed the selector from Parallel to Rhomboid that is the shape you get and so it fits the name

Sierpinsky Crystals Pattern (1).ffxml

deleted to make a new one

So to help Rachel and make her awesome filter correctly and that she does not spend time fixing what is in the above post, I have spent some few hours to:

1 - very carefully position each one of the triangle correctly in each layer

2 - I have using the scale for each edge to be outside of the seed and so now all the triangles have exactly same seed with any cropping and Layer 1 does edge is not going inside the design

I have seen that is nearly impossible to see the errors if you use the 600x600, you must use a very high resolution, so I have used a 5000x5000 Ladybug source image to do it, so this is why I know that Rachel could not do it at all.

Here is the filter that is exactly the same than the one available on the Filter Library (with 5 new presets added) but is fixed the 2 errors told above, and is a pleasure to help you and congratulate again for making this filter.

after fixing your filter as shown here above, I have made also a new version of the pattern making so now I continue with what I have started above

So, here is the new the new filter for making seamless patterns using this awesome filter

1 - Now there is a 4th choice in the Tri-Rhomb-Hex-Patern (changed Parallel to Rhomboid as it about the same)

2 - There are some new presets to show what you can do with this new 4th option

3 - There are scale and offset settings to be able to zoom out or in in the pattern as wanted or to make it fit exactly to be seamless.

I like this SpaceRay it looks great. Did you manage to do a circle version yet?
