Incorrect vertex normals when loading obj file #83
Description
I'm trying to load a very simple obj file:
o Plane
v 0.000000 0.000000 0.000000
v 0.353553 0.353553 0.000000
v 0.353553 -0.353553 0.000000
vn -0.0000 -0.0000 1.0000
vt 0.500000 0.250000
vt 0.500000 0.500000
vt 0.250000 0.500000
s 0
f 2/1/1 1/2/1 3/3/1
When I load the vertex normals using the function load_mesh_vn, I get normals that look like:
[[0 0 1]
[0 0 0]
[0 0 0]]
when I would expect something like this instead:
[[0 0 1]
[0 0 1]
[0 0 1]]
