WebAbstract We present O-CNN, an Octree-based Convolutional Neural Network (CNN) for 3D shape analysis. Built upon the octree representation of 3D shapes, our method takes the average normal vectors of a 3D model sampled in the finest leaf octants as input and performs 3D CNN operations on the octants occupied by the 3D shape surface. Webleaf octants of the tree representation. There are two inter-esting properties related to the preorder traversal property: (1) It clusters spatially nearby octants on B-tree pages in the …
