Requirements

• Python 2.7
• Tensorflow >=1.6

Usage

A trained model for the method with aggregation upsampling is provided for the following Shapenet classes: airplane, chair, sofa, table.

• launch_test.sh : generate a batch of point clouds from the specified class
• launch_train.sh : retrain the network (requires downloading the Shapenet dataset and place it in the data directory)
