lgsvl/simulator

**Technical Summary:** Built on HDRP Unity, the simulator provides high-fidelity 3D environments with native ROS/ROS2 support for testing autonomous vehicle stacks end-to-end. It features direct integration with Apollo and Autoware.auto platforms, procedural HD map generation, and multi-robot orchestration without requiring custom middleware. The architecture uses a web-based cloud UI (WISE) for asset management and simulation configuration, though the core simulator engine can run locally as a standalone executable on Windows or Linux.
