CloudCompare forum

Hello:

This is the first time I deal with point cloud files. I received one, coming from a Leica Geosystems scanner which has 36,146,778 lines. When I read it with CloudCompare there are errors about the first 11 lines.

Perhaps this is a non-standard file format in which the top 11 rows have a special meaning?

TIA

Please find below the first 100 lines of the file in question.

Interesting, this file looks actually a little bit more like a PTX file than a PTS one (the first lines seem to correspond to a matrix, probably the position of the scanner). But it's not a big deal, CC will simply ignore those lines.
