Hi all,

I am running Region_growing to detect only plane on a 3.7 Million point
cloud.
I just call using .detect() so it uses the default parameters.

The detection function has been running for 5 days on single CPU and never
ending.
(I dunno how to make it utilize my CPU resource as it does not have
concurrent flag)

Are there any possibilities that the .detect() function comes to a dead
loop?
Or it is just taking very long time to end?
Would that be parameters problem? like min_points?

Any ways to make the algo run faster?

Thank you very much.
