Track (Vector3D)

module blob contour id spread tracking

about

This contribution helps to restore a certain spread order from a unordered list of coordinates. This is necessary if you do touch detection or even 3D blob tracking yourself or if you use a Tracker, that handles IDs badly.

Instead of doing it in a plugin, I tried to do as much as possible with good oldschool patching. It would not have worked without the advanced spread nodes, so thanks to woei.

The upload includes generic plugin NearestPair, which can be used similarily to ConnectAll or NearestNeigbour.

Hey velcrome nice one this is very usefull. Will try to use it next time the dynamic spread + Unique ID problem comes up again. So far I worked in this case with a fixed spread size in this case and dynamically isert at certain slices the elements of the dynamic spread.

Tnx for sharing

Found some inconsistencies when reactivating ghost IDs and fixed them. also I am now caching Ghost IDs in a special (generically implemented) Cache (Vector3D), that automatically removes IDs depending on their age.

Very nice. This has potential uses for sensors other than just touch too!

This is very useful, and would be even more so if there was a "Previous Slice" output so other associated data could be easily re-ordered. I could not see how to easily modify this patch, so I am using another NearestPairs node after it to get the previous slice positions. Or is it here somewhere and I'm missing it? Thanks!

you are correct, and if you download the most current version here you will see your dream come true ;)
