read_obj: file not found

Thanks for your great work!

Warning: readOBJ() ignored non-comment line 155880:

ValueError: File '/model.obj' not found.

but the model.obj does exists! what happened?

[fwilliams]

The file /model.obj probably doesn't exist. Did you mean ./model.obj?

[fwilliams]

Did this fix the issue?

[Leerw]

sorry, I have not fix this issue, the path is correct, but I delete some prefix personal directories to make it looks clean. I have tried to use the readOBJ in libigl, it worked for me. But why readOBJ in pcu does not work?

[fwilliams]

read_obj in PCU just calls libIGL under the hood and the Python binding should be identical. Can you paste the code you ran and the exact error? Also what OS and version of Python are you using?

[fwilliams]

I've completely rewritten the Mesh IO functions in point-cloud-utils. They are not much more powerful and flexible and shouldn't suffer from the reported bug.

See here for documentation on loading meshes and see here for documentation on saving meshes.
