Supplementary Material of Primal-Dual Mesh Convolutional Neural Networks

Work performed while at MIT. 34th Conference on Neural Information Processing Systems (NeurIPS 2020), V ancouver, Canada. Under Assumption 1, P (M) is a cubic ( i.e.,, 3-regular), planar graph. The medial graph of a cubic plane graph coincides with its line graph. The proposition follows directly from Lemmas 1 and 2.Lemma 3 In the following, we show that PD-MeshNet can be easily extended to handle non-manifold meshes. Figure C.1: The edge collapse operation used for pooling in [ We provide in the following a detail about the definition of the dual features.
