Webconvolution on point clouds, while PointCNN [25] applies Euclidean convolution after applying a learned transforma-tion. Finally, SPLATNet [43] encodes point clouds on a lattice and performs bilateral convolution. All these works aim to apply convolution-like operations to point clouds and extract local geometric features. Webtation of point cloud data is increasingly drawing attention in research. Building deep models for point clouds, sets of orderless points at arbitrary 3D positions, is arguably differ-ent from that for images.
