      • getLight

        public final void getLight​(double x,
                                   double y,
                                   double z,
                                   double[] L)
        Computes the light vector in (x, y, z)
        Parameters:
        x - x-axis coordinate where the light should be computed
        y - y-axis coordinate where the light should be computed
        z - z-axis coordinate where the light should be computed
        L - array of length 3 where the result is stored
