How do you obtain the instance label for each point?

Hi, @laughtervv , @Rotch
Thanks for sharing you nice work. However, I wonder how to obtain the instance label for each point? Since S3DIS dataset only has semantic labels for each point ( 13 categories ) .
Besides, if you have already obtain the instance label for each point, what is the need for block merging?

Thanks a lot!

Thanks for sharing the prepared data set! I've noticed that points of different segmentation labels ('seglabel') sometimes have the same instance label ('pid'). Is this a bug?
