      • actualFrameRateProperty

        public javafx.beans.property.ReadOnlyDoubleProperty actualFrameRateProperty()

      • averageFactorProperty

        public javafx.beans.property.DoubleProperty averageFactorProperty()
        IIR-alpha filter constant as in y(n) = alpha * x(n) + (1-alpha) * y(n-1) typically: alpha ~ Ts /(Ts+T) with 'Ts' being the sampling period, and 'T' the desired IIR time constant
        Returns:
        average factor alpha
