This is a very useful tool to find the Minimum Rotation Frame for a movement from x0 to x1 along a curve with tangent and normal t0 and n0 at x0 and tangent t1 and x1. It is based on the double-reflection method of Wang, Juttler, Zheng, and Liu described in a paper titled "Computation of Rotation Minimizing Frames", from ACM Transactions on Graphics 2008.
