Spa is one of the most iconic tracks on the F1 calendar. It is also extremely large, covering an area of nearly 6km2.
Extreme variations in track altitude, and a huge variation in vehicle speed, make the determinism of TerrainServer between timesteps and runs essential.
The size of Spa means that we must optimise our high-definition track surface to allow deterministic queries of tyre contact patches. At a resolution of 1cm x 1cm, this surface could occupy 50,625,733,000 points at 64 bytes per point – over 3GB of data. Querying any four tyre positions in such a large data set is challenging, but TerrainServer can complete these queries at up to 8kHz per tyre.
Popular with our Formula 1 and World Endurance Championship (WEC) customers, our digital model of Spa is a comprehensive test of a vehicle dynamics model. Aerodynamic grip (in the high speed corners), drag (down the Kemmel Straight) and low-speed performance (in the Bus Stop and La Source) ensure this is a challenging circuit to optimise for.
