Struct QtmCalibrationData

#[repr(C)]
pub struct QtmCalibrationData {
    pub centerBarrierPosition: f32,
    pub translationX: f32,

QTM calibration data (fully enabled/SS3D disabled) in cfg. Usually all-zero on N2DSXL.

Fields

centerBarrierPosition: f32

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. Note: This is the field that System Settings lets you add -1.0 to +1.0 to. Note: Moreover, this field can be directly changed through QTMS_SetCenterBarrierPosition.

translationX: f32

< Lens X coord in inner camera space? Very low value and seems to be unused.

translationY: f32

< Lens Y coord in inner camera space? Very low value and seems to be unused.

rotationZ: f32

< Optimal eye-to-camera angle, in radians, without accounting for lens distortion.

fovX: f32

< Camera’s horizontal FoV in degrees, without accounting for lens distortion.

viewingDistance: f32

< Optimal viewing distance between user and top screen, assuming iod to be 62mm.
