Optimal octree level setting

Hi,

I am trying to process 2 large points clouds with size(117M and 260 M points respectively). What would be the optimal octree level setting while doing cloud to cloud comparison, I know it can never be exactly predicted but wanted to know if such high density files need levels greater than 8 or can lower levels work? Also is it true that higher the octree level more is the processing time?

I processed a similar file and it took a day with a setting at level 8. My system is at 32 GB RAM.

Thanks,

Normally it's automatically deduced by CloudCompare? You should leave it at its default value.

Thank you! The subsampling also really helped, was able to reduce the cloud size considerably and it made CtoC processing faster.
