I have a got a huge pointcloud file and I wanted to compute geometric feature density (based on number of neighbors). I used a value of 0.1 and let it run overnight and when I came back it was not responding. so I assume it's because the file is too big. any suggestions for that?
if I segment this pointcloud to 10 different chunks and apply density with value 0.1 would that give me the same result as if I apply to the whole data?
Thanks.

Yes, apart on the boundaries.

How many points do you have? Are you sure 0.1 is not a too big radius already (which can also explain why the computation takes a lot of time... but not only of course).
