I am not an VRML expert, but I would say that these are faces that
have one face normal, rather than per-vertex normals. In other viewers
these faces are rendered as flat faces with all the same color so all
vertices of these faces must have the some normal vector. Are such per
face normal vectors calculated somewhere?
