This paper describes an algorithm for generating a
guaranteed-intersection-free interpolation sequence between any pair of
compatible polygons. Our algorithm builds on prior results from linkage
unfolding, and if desired it can ensure that every edge length changes
monotonically over the course of the interpolation sequence. The
computational machinery that ensures against self-intersection is independent
from a distance metric that determines the overall character of the
interpolation sequence. This decoupled approach provides a powerful control
mechanism for determining how the interpolation should appear, while still
assuring against intersection and guaranteeing termination of the algorithm.
Our algorithm also allows additional control by accommodating set of algebraic
constraints that can be weakly enforced throughout the interpolation sequence.
