Warping File

This page describes the format of warping files containing the pixel coordinates of each sample of the warping.

The order of the sample are defined as follow:

Bottom Left sample of the Target Image ... Bottom Right sample of the Target Image
... ... ...
Top Left sample of the Target Image ... Top Right sample of the Target Image
Tip: The origin of the pixel coordinate is defined by the PGU axis system.

  • W is the Warping file type:

    • 0: Predefined Mirror Tilt
    • 1: Free Mirror Tilt
    • 2: Step Mirror Tilt

  • X is the number of eyeboxes:

    • defined in the Eyebox section when using the Predefined Mirror Tilt mode, or
    • defined by the Tilt Sampling in the Mirrors section when using the Step or Free Mirror Tilt mode.

  • M is the horizontal resolution of the Warpings:

    • defined by the Horizontal Sampling in the PGU tab when using the Predefined Mirror Tilt mode, or
    • defined by the Horizontal Sampling in the Mirrors tab when using the Step or Free Mirror Tilt mode.

  • N is the vertical resolution of the Warpings:

    • defined by the Vertical Sampling in the PGU tab when using the Predefined Mirror Tilt mode, or
    • defined by the Vertical Sampling in the Mirrors tab when using the Step or Free Mirror Tilt mode.
