CloudCompare forum

I am having an issue with saving in command line. I am getting the errors (An error occurred while saving ‘FILE NAME’: writing error (disk full/no access right?)) and (The third-party library in charge of saving/loading the file has failed to perform the operation.) I am trying to run the code:

CloudCompare -O "File name" -DELAUNAY -MAX_EDGE_LENGTH 5 -SAMPLE_MESH DENSITY 1000 -RASTERIZE -GRID_STEP .2 -OUTPUT_RASTER_Z

When I let the program run with auto save, I get the no access right error. I’ve tried turning off auto save and letting it run, but my computer does not have enough memory for the output at the end after performing the other processes. I have even tried reducing the sample mesh density and clearing the original cloud and mesh but it still won’t output. So I need to separate it into two steps, which means I need to save the point cloud that is created by the sample mesh so I can perform the rasterize in the second step. I tried to manually save in the command line without the autosave using the code:

CloudCompare –C_EXPORT_FMT PCD –AUTO_SAVE OFF -O "File name" -DELAUNAY -MAX_EDGE_LENGTH 5 -SAMPLE_MESH DENSITY 200 –SAVE_CLOUDS

This gives me the third-party library failure error. Is there a fix for this or any way around it? I can perform the process in the CloudCompare program itself, the issue only happens in command line. Also, is there a command to smooth the mesh in command line? I couldn’t find one in the command line wiki.

What's "file name" in effect? In some cases, if the path is too long or if it contains non standard characters, some 3rd party libraries will fail creating the file.

The name of the file was racetrack_2020-01-11-15-46-59.pcd. I tried shortening it to racetrack.pcd and still got the third-party library save error. It attempted to save the sampled point cloud as ./racetrack_SAMPLED_POINTS_2020-07-20_12h00_17_852.pcd but failed.

Do you have any other message of interest in the command line console?

No. Only what I have already said.

Then can you send me the cloud and the exact command line you used? (admin [at] cloudcompare.org)

Hi, same problem here. has been the "access right" problem solved?
i'm using python to launch command line methods. When "auto saving" no problem, but when trying to explicitly save a cloud, it raises the error in the image.
any guidance would be apreciated.
thanks

Which version are you using? And is there any special character in the path?

Hi Daniel, thanks for your attention.
I'm using version 2.12 alpha 64bit
Anyway, It was my bad. Once I passed the whole filepath (instead of just filename which was directing to working path a C:/) it worked as expected.
thanks for this tool

Hi! I had the same problem. I solve it changing the file name and path, which cannot have special caracteres.
