read .ply file using read_pts function

pengsongyou commented 4 years ago

Hi Rana,

First of all, this is really amazing work!!

When I tried to test your method on my own .ply file, your read_pts function at this line gave me an error: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbe in position 210: invalid start byte

Apparently, it is because I have a different way of saving the ply file from yours. I am wondering if you could let me know or provide scripts on how you save sampled points + normals to the .ply files? In this way, I could generate my own ply files :)

Many thanks in advance!

Hi @pengsongyou ,

This error is because your .ply is saved using a binary encoding .

Any .ply can be converted to a non-ascii format via meshlab (export mesh as -> some_name.ply), then make sure that "binary encoding" is not checked, and also make sure that normal are checked.

I also added a script here 48ae6dd532b6efe5412788d50e020d9e14ad73c5 to sample meshes from an input .obj file.

Hope that helps -Rana

Hi Rana,

Thanks so much for your response! Using the provided script, I can now run the code with my own meshes :)

There is one quick following up question: now after running for 300 iterations, I encounter the out of memory issues. I guess it is because my object has a bit more details than your demo objects. Could you please provide some suggestions on this? What parameters should I tune in order to run it without OOT?

Many thanks in advance!
