LitePT: Lighter Yet Stronger Point Transformer

Gradio demo for LitePT (CVPR 2026) — per-point semantic segmentation of indoor RGB scans (ScanNet / Structured3D checkpoints) and outdoor LiDAR sweeps (nuScenes checkpoint). Weights: prs-eth/LitePT. Model code under MIT license (see LICENSE-LitePT).

Example assets

• examples/nuscenes_sample.bin — LiDAR sweep from the authors' demo dataset prs-eth/LitePT_demo (MIT), originally from nuScenes.
• examples/icl_nuim_livingroom.ply — the Open3D living-room fragment reconstructed from the ICL-NUIM living-room scene (Handa et al., ICRA 2014), licensed CC BY 3.0; rotated to z-up for this demo.
