Hello!
I've got a pretty huge scan (the DB file is almost 70 GB large) which I'm generating point clouds of using rtabmap-databaseViewer.
What I find is that when exporting with decimation level 8 and no normal generation, I get all the data I want. If I export at lower decimation levels (4, 2, 1) I get progressively less and less data. With that I mean that portions of the scan disappear, seemingly at random and not related to when in time they were scanned.
Also, if I generate a scan with decimation level 8 and normal computation enabled, the entire thing disappears. The PLY is still large, so there should be data, but I can't see anything when opening the file in a point cloud viewer. I also see that the coordinate bounds of the scan reported by CloudCompare goes to orders of magnitude larger values than they normally would (10e36 is what I recall, although I don't have a broken file handy right now).
Not sure what could be causing this - is there a known upper limit to the size of point cloud that can be exported? Potential upstream issue? Any help greatly appreciated :)
