DeviceParams class

VR headset device parameters. Different headsets have different lens properties.

Constructors

DeviceParams({required String vendor, required String model, double screenToLensDistance = 0.042, double interLensDistance = 0.064, double trayToLensDistance = 0.035, List<double> distortionCoefficients = const [0.441, 0.156], List<double> fovAngles = const [40, 40, 40, 40]})
const
