The Daytona 500 is 500 miles (805 km) long and is the most prestigious race in NASCAR as well as the first race of the year.
Wind Trax, a virtual wind speed and direction visualization that is rendered in real-time with Viz Engine, Vizrt’s real-time 3D compositing engine, was debuted at Daytona 500 by Fox Sports. Wind Trax uses splines imported as .fbx files into Viz Artist. A designer in Viz Artist adds textures and motion effects to the splines that can be changed based upon live data. An NCAM tracking system mounted on a camera in the stadium sends tracking data to Viz Engine. The tracking data combined with live weather data allows Viz Engine to render a real-time representation of the wind direction virtually on the track.
