This is a general software that allows 2D trans-dimensional inference with Voronoi cells and two alternative underlying parameterizations, Delaunay triangulation with linear interpolation and Clough-Tocher interpolation, which utilize the same algorithm but result in either C0 or C1 continuity. These alternatives are better suited to the recovery of smooth models, and result in the posterior probability solution being less susceptible to multi-modalities which can complicate the interpretation of model parameter uncertainties.
