Cockroach PointCloud Cluster parameters for huger pointclouds

Hi there,

I have a question concerning Cockroach.

When trying to find clusters in a huge pointcloud (11.399.329 points) I retrieve very strange results.
The scale is in mm (I could as well change it to m if that’s a problem).
To me it seems that there should be enough planar areas to be clustered. So I tried a few settings here:

Setting: EPS=0.1 Neighbours=20
Same result as above, only that the small clouds are only 4.

Setting: EPS=1 Neighbours=100
Calculates for at least 30 min and does not give me a result.

@Petras_Vestartas what would the settings be to receive a good result?

I believe, Cockroach cannot really handle huge pointclouds for clustering well.

Cockroach was running cilantro library:
kzampog/cilantro: A lean C++ library for working with point cloud data

Seeing questions on mcneel forum, it would be good to restart Cockroach development from scratch, solely on C++, no C# no Python, just simple Rhino Commands, otherwise we are lost in wrappers and cannot debug properly…

Once I have more time, I want to take a look at this. For now I just can answer sorry, nope.
