pdal truncating values when writing ply
Geographic Information Systems Asked by crEO on April 23, 2021
When using pdal to either translate to ply file or split a ply file in smaller chunks, it appears to be truncating values so I end up with point clouds with stripping. This does not occur with other formats – but I need .ply in particular.
E.g. when splitting up a bigger file….
pdal split --capacity 1000000 in.ply out.ply
… I end up with the result below for the subsets. Are there parameters that may stop this from happening? (See the below pic)
One Answer
This is actually a precision problem where PDAL trim automatically some decimals.
You need to control that with this option : --writers.ply.precision=6f (it say to the ply writers to have 6 decimals)
