I have a question.
Is there any limitation concerning number of points when saving point cloud? I faced the following problem:
After merging 2 pointclouds i got the final point cloud with 480 milion points. When saving this merged cloud either as .ply or. .txt CC crashes - it either writes error while saving in command line or (in case of .ply saving option) saves the file - but in fact this new file is in size smaller than previous ones that have been merged and of course cannot be reopened as it is damaged.
CC is run on workstation (8 core processor, 190 Giga RAM, GPU NVIDIA Geoforce 780).

Re: Point cloud saving problems
Hi,
Theoretically there shouldn't be any limitation (especially as no memory should be consumed by the process). Maybe there's a limitation on the file size (i.e. > 4 Gb) but I thought it was only for old operating systems... I'll try to conduct some tests on my side.
Are the point clouds blank or do they have colors/normals/scalars, etc.?
What's the PLY output file size?

Hi Daniel
Both merging clouds have x,y,z, RGB values and scalar field.
And final merged one has all these values as well.

Re: Point cloud saving problems
And as to .ply file size:
1. cloud :size 5 G
2. clod: size 1 G
And obviously not proprely saved merged cloud - its .ply has 3 G

Strange...
Now I changed destination directory for saving and it works :)

Re: Point cloud saving problems
Very strange indeed!
With both formats?!
And what version are you using by the way?

Re: Point cloud saving problems
It was definately problem with destination drive. The procedure itself works fine :)
Sorry for causing panic.

Re: Point cloud saving problems
Problem was very trivial.
Destination drive was almost full that is why CC could save only part of the file ... :)

Re: Point cloud saving problems
Yes but it's still a potential bug ;).
There was a bug with non standard characters in file paths but it should be fixed in the last beta release.
