I have this pattern in a JPEG format. I would like to place center points based on Black and White areas. Any ideas how I can proceed from here? [Center Points]

I think I got it. I used List.SortNatural to get the points sorted. Thanks for helping everyone. [Done]

I have it started, but pretty new at Dynamo [InDynamo]

Please find my linked JPEG file here [Pattern002]

look at the Dynamo Primer There is an example of using zero touch with the AForge library that is almost identical to what you want https://primer.dynamobim.org/11_Packages/11-5_Zero-Touch.html

A good place to look @Andrew_Hannell and a good place for you to get some python tips @mkom You could try the below to get you going, and then adjust for your workflow… [image]

Worked perfectly. Thanks @Ewan_Opie ! Is there a way to separate points so that they correspond to black and white areas? [Separate Lists]

Thank you Andrew! I’ll definitely take a look at it.

[image] mkom: Is there a way to separate points so that they correspond to black and white areas? List.GroupByKey using the brightness at a given pixel location as the key should do the trick.

Thanks Jacob! Do you have any similar examples of List.GroupByKey using brightness that you can recommend to look at? I am having difficulties making it work. Points Grouping.dyn (46.1 KB)

mkom, you will have to ask each point if that point is in a dark or light area, then you can use that data (a list with 1/0 to filter by :slight_smile: ) I’ll take a look at your script

Hey i got it! Take a look at this: [image] 2020-04-10 Points Grouping.dyn (43.3 KB) Also just a quick question, what are you going to do with this?
