Abstract
We present an algorithm for generating a twice-differentiable curve on the rotation group SO(3) that interpolates a given ordered set of rot ation matrices at their specified knot times. In our approach we regar d SO(3) as a Lie group with a bi-invariant Riemannian metric, and appl y the coordinate-invariant methods of Riemannian geometry. The resulti ng rotation curve is easy to compute, invariant with respect to fixed and moving reference frames, and also approximately minimizes angular acceleration.
