CloudCompare forum

Hi there,

I was trying to output a point cloud with size about 90 million points into pcd format, but CloudCompare quits in the middle of the processing without any error message.

The export can be successfully done if the size is lowered down to 20 million points.

Any idea?

Thanks.

Hum, the export is actually done by the PCL library, but I'm not sure if there's a limit (I would assume not). How much memory (RAM) have you on your PC?

Thanks for the reply.

My PC has 32GB ram.

Ah! Then it's definitely not a RAM issue ;). Probably an issue with PCL then?

Hi Daniel,

Yes, I think so because the same point cloud can be saved as .e57 format without any problem.

In the case of pcd export, Cloudcompare just quits quietly within 10 seconds or so after clicking the "save" button without the export dialog even pops up.

Is there any way to upgrade the pcd library?

Thanks.

Hum, you have to recompile CC with a newer version of PCL. But I'm not sure it will fix the issue... Ideally someone should run the project in Debug mode and see what happens. Do you reproduce the issue with any cloud? (over a certain size)

Thanks for the reply.

The problem comes when the size goes over about 50 million points. For the successful case, the size was 20 million points.

Sorry for my ignorance, how to run the project in Debug mode?

It's easier with Visual Studio for instance (where the default configuration is "Debug" and then you just need to start with the Debugger - F5 - and put breakpoints near the area of interest, then run step by step). But you can also do that with other compilers (MinGW, gcc, etc.) and use GDB for instance to do the same.

Thanks, Daniel. will give it a try.
