OBJ Reader: Does not load 3D Texture coordinates
I have an OBJ file which has "vt x,y,z"
I tried setting up for requesting the texture coordinate as 3D
mesh.request_halfedge_texcoords3D();
when I query the resulting data, I get lots of zeros and the occasional NaNs.
If I request for texcoords2D(), it works fine.
I just want to find out if this is a known limitation or bad coding on my part in calling functions in OpenMesh.
I am using OpenMesh 4.1
