Technical notes for the ATG projects: tyre models, vehicle audio and the Unity workspace setup behind them. Written while building, so it reflects what the code actually does.
How the tyre model is set up and used, with an interactive visualiser for the parameters.

ATG Simulator is a passion project by one person, built in Unity and aimed at realistic vehicle physics. These pages are the technical side of it: the notes, models and setup guides that the projects run on.
It started with ATG Kish, which tested whether a real place could be rebuilt in a digital one. That project is finished and served its purpose. The work continues in ATG Racing, a browser based simulator where the physics gets solved, and in ATG itself, the Windows game whose first Ground is the island of Pardis, from the Persian word for paradise.
