Field Documentation

BOOL _NV_FOVEATED_RENDERING_GAZE_DATA_PER_EYE::bInSaccade

(IN) Use flag NV_GAZE_EYE_SACCADE_DATA_VALID. Denotes whether eye is currently in saccade movement or not.

float _NV_FOVEATED_RENDERING_GAZE_DATA_PER_EYE::fEyeOpenness

(IN) Use flag NV_GAZE_EYE_OPENNESS_VALID. Unused at the moment.

float _NV_FOVEATED_RENDERING_GAZE_DATA_PER_EYE::fGazeDirection[3]

(IN) Use flag NV_GAZE_DIRECTION_VALID. Normalized direction of the gaze of the eye. Used for calculating the gaze location using the FOV.

float _NV_FOVEATED_RENDERING_GAZE_DATA_PER_EYE::fGazeNormalizedLocation[2]

(IN) Use flag NV_GAZE_LOCATION_VALID. Precalculated normalized gaze location in limits (-1 to +1) for X and Y. Center of the screen denotes (0, 0). If this is valid, this will be given higher priority than direction.

float _NV_FOVEATED_RENDERING_GAZE_DATA_PER_EYE::fGazeOrigin_mm[3]

(IN) Use flag NV_GAZE_ORIGIN_VALID. Origin of the eye in millimeters. Used mainly to detect whether Left Eye or Right Eye.

float _NV_FOVEATED_RENDERING_GAZE_DATA_PER_EYE::fGazeVelocity[2]

(IN) Use flag NV_GAZE_VELOCITY_VALID. Optional: Velocity of the eye on the normalized space in each direction. Central foveated region would be skewed in the direction of the velocity.

float _NV_FOVEATED_RENDERING_GAZE_DATA_PER_EYE::fPupilDiameter_mm

(IN) Use flag NV_GAZE_PUPIL_DIAMETER_VALID. Unused at the moment.

NvU32 _NV_FOVEATED_RENDERING_GAZE_DATA_PER_EYE::GazeDataValidityFlags

(IN) To be populated with OR'ing flags from NV_GAZE_DATA_VALIDITY_FLAGS

NvU32 _NV_FOVEATED_RENDERING_GAZE_DATA_PER_EYE::version

(IN) Version of the structure
