[Paraview] Read a custom point stored in ply file

[Albert Mosella-Montoro]

Hi Utkarsh,

Looking at the PLY reader in VTK, it looks like it doesn't support

Thank you!

In fact I am working like this at this moment. I would like to move to ply
files but if at this moment is not possible I will wait.

Sorry I wrote wrong the format is not plc is pcd.  I think is very similar
to ply http://pointclouds.org/documentation/tutorials/pcd_file_format.php.
In my case insted of X Y Z RGB I will have X Y Z DX DY DZ fields.

The motivation of the change to ply or pcd is because ply or pcd have a bin
version of the files and I am looking for a standard bin file that paraview
can manage. Can you recommend me any binary file that paraview can manage
without issues with custom parameters like on my case?

Thanks,

Albert
