PointNet.pytorch

This repo is implementation for PointNet(https://arxiv.org/abs/1612.00593) in pytorch. The model is in pointnet/model.py.

It is tested with pytorch-1.0.

Performance

Classification performance

On ModelNet40:

On A subset of shapenet

Segmentation performance

Segmentation on A subset of shapenet.

Note that this implementation trains each class separately, so classes with fewer data will have slightly lower performance than reference implementation.
