We present a novel method for computing correspondences between subdivision surfaces, represented as functional maps. We leverage two main advantages of the hierarchical structure: (1)
the spectral basis functions, which are multi-resolution by construction, can be succinctly represented on a subdivision surface, and (2) the pointwise map reconstruction can be done hierarchically. Using these properties, we design a computational pipeline for finding correspondences between high resolution meshes which is much faster than existing approaches.
We show how the computed correspondences can be used for detail transfer between artistdesigned subdivision surfaces.
