I want to know how to calculate rotation angles using inverse kinematics. I am planning on using this for real time 3d animation. Anyone know of some good literature that details a specific solution?

Thomas Kane is one of the world's authorities on dynamics. I'd recommend his "Dynamics" text highly, but it's not for the faint of heart or weak at mathematics.

Does this book detail a specific mathematical solution for solving 3 dimensional inverse kinematics?
Mr Bell
See page 4 of this article: http://bledsoebrace.com/studies/Ankle1_RMML.pdf. It shows Kane's differential equations for the problem. Don't know if that's what you have in mind.

From wikipedia:

The ikfast program can solve for the complete analytical solutions of most common robot manipulators and generate C++ code for them. The generated solvers cover most degenerate cases and can finish in microseconds on recent computers.
