I'm not aware of any books that deal with the 3D capabilities of Blitz3D - they all seem to just focus on 2D stuff, AFAIK.
Your best bet to learn 3D is to look at the provided demo code and code archive stuff, experiment lots and ask lots of questions on these forums. You'll be surprised how quickly you pick up the basics. :)
