Point Geometric Features

📌 Description

Python wrapper around C++ helper to compute the following local geometric features in parallel on CPU:

• linearity
• planarity
• scattering
• verticality
• normal_x
• normal_y
• normal_z
• length
• surface
• volume
• curvature

🧱 Installation

Tested

# clone project
https://github.com/drprojects/point_geometric_features.git
cd point_geometric_features

# Installation in a dedicated conda environment
bash install.sh

🚀 Demo

python demo.py

💳 Credits

This implementation was largely inspired from Superpoint Graph. The main modifications here allow:

• parallel computation on all points' local neighborhoods, with neighborhoods of varying sizes
• more geometric features
• some corrections on geometric features computation
