Methods

alpha

  • alpha(cutoff): number

  • Calculates the alpha value used for smoothing in the filter, based on a cutoff frequency.

    Parameters

    • cutoff: number

      The cutoff frequency at which the filter should attenuate the signal.

    Returns number

    The calculated alpha value for the filter.

filter

  • filter(qNewRot, timestamp): quat

  • Applies the filter to the given value using the current filter configuration and updates the internal state.

    Parameters

    • qNewRot: quat

      The new value to be filtered.

    • timestamp: number

      The timestamp associated with the value, used to calculate the dynamic parameters of the filter.

    Returns quat

    The final filtered value

reset

  • reset(): void

  • Resets the internal state to uninitialized.

    Returns void
