This is the implementation of the rotation invariant convolution and neural networks for point clouds as shown in our paper. The key idea is to build rotation invariant features and use them to build a convolution to consume a point set. For details, please refer to our project.

The code is written in TensorFlow and based on PointNet, PointNet++, and PointCNN. Please follow the instruction in PointNet++ to compile the customized TF operators.
The code has been tested with Python 3.6, TensorFlow 1.13.2, CUDA 10.0 and cuDNN 7.3 on Ubuntu 14.04.
