Hi Chris,

Would it be possible to modify the 9-point calibration to 3-point calibration? 3 points should still be enough to get a reasonable fit to start with. It would provide a smoother transition from monkey barely fixating at one point to fixating at all 9 points.

Thanks,

    Hi Sujay,

    The standard eye calibrator fits a second-order function that has six parameters, so you need at least six samples to perform a fit. However, the linear eye calibrator fits a first-order function with three parameters, so three samples would be sufficient to get a fit with it.

    Cheers,
    Chris
