Both interfaces use the same simulation. Rendering belongs to the browser side.

Full race view or individual components

A complete race

The complete browser view includes the track, cars, controls, and timing. On this site, selecting a driver opens its project.

Individual components

Mount the race canvas, timing, controls, and telemetry into separate parts of a page. A shared controller keeps each view connected to the same race.

Headless control and browser playback

The headless environment exposes reset and step operations for custom controllers. It runs without PixiJS or a browser, with observations and actions for testing driving policies.

Bring the controller back to browser playback to inspect its braking, track limits, and recovery.
