[Qgis-user] First steps with 3D Scan Data?

[Benjamin Ducke]

Hi Bernd,

.rwcx is the proprietary point cloud output format
of Trimble terrestrial laser scanners.

I am not aware of any open source software that
can read this format. Your best chance for pointers
to software that can handle this format would be
a CAD/BIM or laser scanning forum.

Once you have managed to convert this to something
that is more interoperable (PLY or OBJ, for example),
your next stops should be CloudCompare and/or MeshLab
(the latter is extremely powerful but takes a lot of
time to get used to).

Best,

Ben
