Reducing Point Cloud File Size

[Aya_1979]

Hi Everyone,

I am new to both the forum and the CloudCompare software.

My main job here with cloudcompare is only how to reduce the number of points and subsequently the file size to be able to import the e57 file into ArchiCAD which unfortunately has a 4GB limit for importing.

I opened the e57 in cloudcompare and found all the buttons inactive and just don't know where to start.

Appreciate your help.

You just need to select / highlight the cloud in the DB tree and then use the 'Subsampling' tool:

And for very big files you can also use the command line version (it's faster):
http://www.cloudcompare.org/doc/wiki/in ... _line_mode (see the -SS option)

Thanks Daniel for your quick response.

It worked and I managed to reduce an 8 GB point cloud file to 3.5 GB.
