I'm not an artist so I'm going to get stoned here, but I think 3D graphics are closer to theater than photography. Poser, for example, is usually a collaborative effort, it uses lights and cameras, you dress "actors" and put props in their hands, set and costume design is involved, and the most interesting results (to me) display a dramatic scene. The best of it aspires to be original, the worst of it is plagarism of what has gone before; the best of it stimulates, the worst of it bores. No one will ever agree on what art is but the resulting conversation is often fascinating.
