eyePositionLeftX

double eyePositionLeftX

position of the left eye in device coordinates, unit is mm

• (0, 0, 0) is in the center of the device
• x-coordinate: positive towards the right side of the screen
• y-coordinate: positive towards the top of the screen
• z-coordinate: distance in front of the screen

check eyePositionLeftX != InvalidValue before using it

eyePositionRightX

double eyePositionRightX

position of the right eye in device coordinates, unit is mm:

• (0, 0, 0) is in the center of the device
• x-coordinate: positive towards the right side of the screen
• y-coordinate: positive towards the top of the screen
• z-coordinate: distance in front of the screen

check eyePositionRightX != InvalidValue before using it
