In this solution to the shape interpolation problem, the algorithm constructs compatible hierarchical representations of two given shapes. Interpolating the compatible hierarchical representations generates smooth interpolation sequences.

By blending arcs, this interpolating subdivision scheme for curves on the sphere produces fair-looking G2-continuous curves even through challenging sets of interpolation points.
