• Semantic Segmentation of Point Clouds with PointNet++

  Published:Jun 28, 2026 |  at 12:30 PM

  A practical guide to semantic segmentation of 3D point clouds with PointNet++. Learn why point clouds are hard for neural networks, how PointNet++ builds a hierarchical feature representation with sampling and grouping, and how to implement the key building blocks in PyTorch, with a worked example on the S3DIS indoor dataset.

• Gaussian Splatting vs. Traditional Photogrammetry
