On the basis that's impossible to extrapolate your experience from such a terse post.

For one thing, 3D graphics is heavy on the maths, so some decent math texts wouldn't go amiss either. It's all very well that the APIs handle a lot of this stuff, but there's a lot of theory as well which a few tutorials and google just won't solve.
