Point cloud completion aims at predicting dense complete 3D shapes from sparse incomplete point clouds captured from 3D sensors or scanners. It plays an essential role in various applications such as autonomous driving, 3D reconstruction, augmented reality, and robot navigation. Existing point cloud completion methods follow the encoder-decoder paradigm, in which the complete point clouds are recovered in a coarse-to-fine strategy. However, only using the global feature is difficult and will lead to blurring of the global structure and distortion of local details. To address this problem, we propose a novel Partial-to-Partial Point Generation Network (
