Data Fields
float	centerBarrierPosition
	Neutral (center) barrier position/offset (with slit width of 6 units), when the user is facing directly facing the camera, that is to say, their eye midpoint normalized X coord in the camera's plane is 0, assuming the user's head is located at the expected viewing distance and at the expected eye-to-camera angle (as per the rest of this structure). More...
float	translationX
	Lens X coord in inner camera space? Very low value and seems to be unused.
float	translationY
	Lens Y coord in inner camera space? Very low value and seems to be unused.
float	rotationZ
	Optimal eye-to-camera angle, in radians, without accounting for lens distortion.
float	fovX
	Camera's horizontal FoV in degrees, without accounting for lens distortion.
float	viewingDistance
	Optimal viewing distance between user and top screen, assuming iod to be 62mm.

Detailed Description

Field Documentation

centerBarrierPosition

float QtmCalibrationData::centerBarrierPosition

Neutral (center) barrier position/offset (with slit width of 6 units), when the user is facing directly facing the camera, that is to say, their eye midpoint normalized X coord in the camera's plane is 0, assuming the user's head is located at the expected viewing distance and at the expected eye-to-camera angle (as per the rest of this structure).

This is expressed in terms of iod/12 units modulo iod/12 (thus, range is 0 to 11 included), with IOD (interocular distance) assumed to be 62mm.

Note

This field is floating-point for QTM auto-adjustment purposes, however the actual barrier position in hardware is an integer.

This is the field that System Settings lets you add -1.0 to +1.0 to.

Moreover, this field can be directly changed through QTMS_SetCenterBarrierPosition.
