Hi, I know this is over 1 year old, but as many others i am interested in this topic. Not necessarily for the sake of actual pixel sorting, but for the more general problem of n-dimensional sorting, and color sorting is a nice visual example of this actually since each color is at least 3-dimension…

[image] Pisicandru: How do you do the transformation from RGB to this negative number? I read the processing help for color, but i still don’t understand it. They aren’t actually “negative numbers” in any meaningful sense. All values with alpha greater than 50% have their first bet set – whic…

Hi Jeremy, That really helps, especially the equation you provided which i re-wrote as: (A256^3)+(R256^2)+(G*256)+B with proviso if A>127 then multiply by -1 This gives me a transformation from 4 dimensions to 1 dimension even if the numbers are meaningless. The idea is that if the transformation…

[image] Pisicandru: When working in n-dimensions Ah, I think I see what you are doing. Are you trying to map n-dimensional coordinates to unique Processing colors? Can you give an example or examples of N? Is n usually 4, 5, 6, or is n sometimes 20, 50, 200? Also, what kind of coordinate ra…

Just realized this was all on a year-old post from someone else – splitting.

I assume that your goal is N-dimensional sorting and that the color thing is only a metaphor or a bridge to find a solution. Because with colors it works. Maybe you got weather data with 7 Dimensions you want to sort?

Ah. If sorting properties of multidimensional data in general is the topic, you might also be interested in this thread… [image] Generative floor plans with Permutation algorithm Processing.py Dear all, I would need your help to implement a permutation algorithm allowing…

Hi, For now i am thinking in a more abstract way, but certainly there are lots of multidimensional data out there, from multi-spectral satellite data, to more “normal” satellite data with 4, 8 or 16 bands, weather or climate data, geochemical data, pollution, etc. There are also pretty well (and no…

If you like R – you might also try Processing.R mode so that you can manipulate your high-dimensional data using familiar matrices and syntax but render it with the Processing API. [image] processing-r/Processing.R :coffee: :paintbrush: :1234: R Language Mode in Processing for Creative Co…

I wonder about the famous comparator class If I had a Adress field I would sort by last name, then by first name, then street name, then house number No need to unify them to a long number like color? Possible?

Hi, Jeremy, thanks for the Processing.R, i definitely will look into it. But having time on my hands i will try to learn a little bit of Processing as well, although for a long while i will still be tempted to try it first in R :wink: Chrisir, i am not sure i understand your question. The comparat…
