CloudCompare forum

Hi Daniel,
first of all thank you for your great job.
I encounter a problem when trying to save very big point cloud files in PLY format. When the number of points goes over 1.8/2 billions points I get an argument exception error for the PLY file. I had no problem with other file formats, such as exporting a 180Gb txt or a 60Gb e57 files. As I succeeded in exporting txt and e57 I exclude it being a problem of RAM on the machine...
I would like to know if it is some limit in the file format or it is a problem of my cloud.
Thank you for your kind attention.

Maybe not a limit of the format, but more of the library we use to generate ply files? (RPly). Internally, they may rely on some integer values that will only allow to represent/manage point indexes up to 2 billion...
