A good resource for rendering reflective objects?
I know there's a method to the madness when it comes to curvaceous and reflective objects, and it's something I partially understand already (though I know I've got a long way to go).
So I'd like to try to find a book or comprehensive guide on the web to the theories involved in the bent/reflectied light on metals and other similar surfaces.
I checked on Amazon and was surprised to have found nothing! (Perhaps I didn't look well enough?) I would have expected perhaps a resource for industrial designers or something...
I'm aware that observational drawing and maybe rendering shiny objects in 3D might also help, but I'm looking for some hard theory right now.
So, any recommendations?
