Are they vertex or face normals? Could you please share an example file that could help us reproduce the issue?
armadillo_pc.obj.zip they are vn, and I tried to compute normals of vertices by meshlab and save. When I loaded again, it also didn't have normals.
Thanks. I see that meshlab never supported load of vertex normals from obj files... Marking as feature request
I'm fairly certain that OBJs don't support point cloud normals. Normals are assigned to a specific vertex using either the face f
or freeform surface surf
commands [ref]. If there is a standard way to do this in an OBJ file, though, I would certainly like to know about it.
The easiest alternative is to use PLY.
Thanks for your reply😁
Macos, 2021.05 and 2021.07. When loading a point cloud with normals in .obj file, meshlab cannot load the normals. And I also tried on win64, 2021.05, it didn't work.
