Engineering notes on synthetic LiDAR, labeling, and the data pipeline.

Short reads from the team building SiRLab: how we simulate weather, benchmark co-simulation, and keep point-level labels precise.

How we generate real-time synthetic LiDAR for simulation and production datasets

Real-time synthetic LiDAR aligned to RGB and labels (stencil IDs), with GPU-resident reconstruction from render passes for dataset-scale throughput and closed-loop simulation.
