SpiderCNN is a convolutional neural network that can process signals on point clouds.

Installation

The code is based on PointNet， and PointNet++. Please install TensorFlow, and follow the instruction in PointNet++ to compile the customized TF operators.
The code has been tested with Python 2.7, TensorFlow 1.3.0, CUDA 8.0 and cuDNN 6.0 on Ubuntu 14.04.
