We show that Möbius transformations preserve the rotation-minimizing frames which are associated with space curves. In addition, these transformations are known to preserve the class of rational Pythagorean-hodograph curves and rational frames. Based on these observations we derive an algorithm for G1 Hermite interpolation by rational Pythagorean-hodograph curves with rational rotation-minimizing frames.
