Extract walls lines from Point Cloud

I’ll do an indicative demo as soon as I have some 10 minutes to spend:

Given an user controlled (via a bias to 1 probability variable) List of 1s and 0s do the sequence grouping and then “join” the groups (with 1’s) according a user gap value. Obviously these correspond to some Pts indices. Rather plain/entry level stuff but I’m in the middle of some chaos at the practice right now … PLUS (for an intergrated full demo) this w/e is the USA F1 soad opera (forza Lewis).

All that are elementary via code … but they are kinda a Chinese poem to you (since you are not in the coding thing). For instance this does a classic sequence grouping:

I hear you: what sort of Chinese things are these? You tell me.

BTW: Some ugly - but honest - news: this (for some thesis worth the name … i.e. something that brings new fruits to the party) … is rather well above you: I predict some stormy weather around. What about some Plan B? (or Z).

Update: while crisis is escalating (life sucks) found 3 minutes to sample some existed stuff (I have about 50+K C# things).

So this is the rnd sequence:

This is the “translation” to a Pt list (it’s a demo after all):

And this is the Clustering:

So Cluster at {1} should been united to {3} IF and only IF {2} has less or equal (to gap) items … blah, blah. And if max gap = 3 … Cluster {6} means another Line. Elementary my dear Watson.

Cross fingers for some 7 minutes more (or maybe 8).
