For the past few days/weeks, I've been working on replacing liblas with PDAL. (GitHub)
At the moment the las reader is on par with what was done with liblas (or almost).
The las writer is almost done I would say, it need more testing, so if anyone has some "tricky" files to test...
As PDAL supports more las version (1.3 and 1.4) it supports more point format.
I think it would be great feature to allow the user to choose the las version and point format when saving to a Las file.
I tried to keep the las filter's code as close as what was donne with Liblass however PDAL gives a higher level interface (for example saving extra fields into a las should be relatively easy with), so maybe some things could be changed/modernized.
I Tried to compile on windows but haven't managed to ...
I can compile "vanilla" CloudCompare, I can compile PDAL but when linking both, it fails.
However on Ubuntu it works fine.
