@Kuboå So you want to know which point is on the far left? After sorting, the lowest value is the point with the index $15$, which is why it is assigned to point $0$. therefore you have to use Sample Index to fetch the sorted value, and make a comparison with the current index of the points. Something like this: i.sstatic.net/o8TQ3.png

Dec 1, 2022 at 19:44 | comment | added | Kuboå | @quellenform Yes that makes sense, thank you. Although I can follow and recreate the sampling position example just fine, I still got stumped with my scenario above, however. I think if you can tell me what I'm doing wrong trying to create a selection for the left-most point by (the now sorted) index here, it'll finally click. | |

@Kuboå This setup is NOT a reorganization of the points, but only a mapping of the indices. Have a look at the file with the comparisons. There you see, for example, that in the group "_Visualize" I transfer these mapped indices with Sample Index to the positions of a line. So the sorted index only says which point should put at this index, and it depends on you what you do with this information. Does this make more sense to you?

Dec 1, 2022 at 17:14 | comment | added | Kuboå | Thank you all for this great Q&A. I can't seem to figure out how to use these though, could someone point out what I'm doing wrong in this setup, for ex: i.imgur.com/TDa1FpN.png ? I expect a new order that goes from left to right, but I get this seemingly random one instead. I get the same order from all other method node groups as well so obviously I'm messing something up. Thanks! (File) | |

Jun 6, 2022 at 19:18 | comment | added | Markus von Broady | Nice update! However I find resolution sorting definitely more performant than quadratic sorting. | |

Jun 6, 2022 at 8:54 | comment | added | jst kiko | @quellenform if it wouldn't take to much of your time, could you update the question with "resolution based sorting". I would like to see how it compares to other methods. :) | |

nice comparison, though circular sorting doesn't get much slower because it just diregards more and more points. For my test of 5000 points, 4585 (91.7%) remained unsorted: i.imgur.com/9reNsbg.gif - so it's like taking my solution, removing 91.7% points, and then sorting 500 points instead of 5000 points. Still, it's a problem in itself to figure which points to remove, so I might actually use the Circular Sorting in the future... Also consider this: $\bbox[red, 5px]{\color{white}{\mathbf{NO}}}$ (color table)
