Yes -- if you use flat shading (the default, as opposed to smooth shading),
then normals are defined per facet.  They're displayed per vertex
for OFF objects, but that just mean you see a cluster of normal-vectors
at each vertex, one per adjacent face.

(If you use smooth shading, then you see a single normal at each vertex
which is a sort of weighted mean of the adjacent face normals.)

Other object types: QUADs have per-facet normals, and MESH normals are
a bit strange, I'd have to look at the code to see exactly what's displayed
for a normal vector.  But OFF objects behave as you'd probably wish.
