v3.6.0

Release date: 2024-10

New Features

  • New 3DGS Intersection scene: Built using the latest 3D Gaussian Splatting (3DGS) technology, designed to provide an end-to-end perception closed-loop simulation environment.

  • Point cloud map engine and toolchain support: Import point cloud maps beyond OpenDRIVE to solve the external map input problem for data-driven closed-loop simulation, with support for unstructured roads.
  • 4D millimeter-wave radar: Added a physics-level 4D millimeter-wave radar sensor model.

  • External asset packaging plugin: Added a UE packaging plugin that simplifies the process of mounting external assets to SimOne, effectively improving workflow efficiency and user experience.

  • Semi-intelligent traffic agents: Resolves collision issues in collected data, improving the usability of real-world recorded data and the diversity of traffic flow.

Improvements & Bug Fixes

  • Scene generation optimization: Improved the quality of automatically generated scenes and enhanced art asset quality; supports point cloud maps.

  • System architecture and dynamics node optimization: Supports 1000 Hz high-frequency updates, effectively reducing latency in HIL simulation.
  • Developer documentation: Reorganized the developer workflow and related tutorials to help developers get started more easily.
  • Night scene effect enhancement: Enhanced perception rendering for the three-lane night scene in the atomic map.

  • Bug fixes: Fixed several known issues.
