Can't write file (exported point cloud)
« on: November 21, 2022, 05:31:45 PM »
Hi there,

I am trying to export a point cloud as an .obj file, but after a week of processing, I got this error. Any reason for this error and to how to prevent it again?

Best,

Sam Frederickson

Exporting point cloud as obj file is not good idea, because obj is text based format and writing positions, normals and colors as text representation with 5 decimal places takes very large amount of disk space and processing time. Use some binary format(e.g. ply), which needs just 3 times less of disk storage and wirting times are much much faster.

Hello Sam,

How many points are there in the point cloud that you are trying to export and which export parameters have been used?
Probably, the export failed after there was no free space left on the target drive, due to the non-binary OBJ format.
