Field Documentation

float QtmTrackingData::eyeCameraCoordinates[QTM_EYE_NUM][2]

Normalized eye coordinates, for each eye, after accounting for lens distortion, centered around camera.

X coord is in the -1 to 1 range, and Y coord range depends on inverse aspect ratio (-0.75 to 0.75 on real hardware).

Note: On real hardware, X coord equals ((rawX / 160.0) - 1.00) * 1.0639 before clamping.; On real hardware, Y coord equals ((rawY / 160.0) - 0.75) * 1.0637 before clamping.

float QtmTrackingData::eyeWorldCoordinates[QTM_EYE_NUM][2]

Normalized eye coordinates, for each eye, in world space.

Corresponds to eyeCameraCoordinates multiplied by tangent of field of view.

Note: On real hardware, X coord equals eyeCameraCoordinates.x * tan(64.9 deg / 2).; On real hardware, Y coord equals eyeCameraCoordinates.x * tan(51.0 deg / 2).
