I'm trying to make a patch which would follow blobs coordinates and sort the coordinates in order to hook them up with visual GL elements.

I'm sure it's a simple list merging math but for some reason the answer avoids me desperately - I have a project deadline coming very soon...

you might try [zl lace] to merge the X, Y coords into a paired list, then [zl iter 2] to spit them out as pairs. Or you can unpack the lists separately and merge each pair, then these go to the position of your GL objects.

On the outcoming matrix with the coordinate pairs, you can use jit.spill to make normal numerical lists out of them, and with "listlength 5" you'd only have up to 5 blobs in the outgoing list, for example.

It makes my life a lot easier although it doesn't completely solve the problem - maybe I explained it not too precise - please take a look at the photo attached to see what's going on.

When I have a few people walking near one another I get 3 blobs but 2 different colours in centroids.sort.

Lowering the threshold doesn't solve the problem because then the centroids.sort gets too sensitive, and the colours it produces as sorted start flickering.

how to BOTH follow the sort number the centroids.sort produces AND at the same time separate for example 3 different sets of coordinates even if centroids.sort recognises only 2 kinds of blobs?
