PLY & LAZ file issue with latest 2.5.laszip.2

Post by Jason Warren »

Hi,
I have installed the latest version and when I save a PLY file and then open it in MeshLab the data isnt loaded correctly. Only a sample of the points are displayed, in a gridded manner?
If I perform the same task in the previous version [2.5.2 no laz] the PLY file opens perfectly in MeshLab?
Also, on LAZ import, if the file contains multiple scanworlds, the scanworlds are layered on top of each other with the wrong transformations as registered?
Anyone else experiencing the same?

I could not reproduce the bug with PLY files on my side (nor with the 32 or the 64 bits, and in BINARY or ASCII mode). But the 'gridded' manner looks like an issue with big coordinates. Does your file has a 'global shift' or global scale applied at loading time?

And for the LAZ file most of the work is done by the liblas and laszip libraries. I didn't even now that there could be multiple "scanworlds" in a file ;). I guess this feature wasn't working with the version 2.5.1 either? Can you share such a sample file with me?

Hello Daniel,
Thank you for the fast reply. With regards to your requests I will try and post more information and screen shots later today. For data transfer I typically use WeTransfer for sending data, and would need your email address to do this, unless you have an alternative method?

Best regards,
