    • minMaxScaling

      public static double minMaxScaling(double x, double oldMin, double oldMax, double newMin, double newMax)
      Changes the scale of a value from one range to another.
      Parameters:
      x - input
      oldMin - initial lower boundery
      oldMax - initial upper boundery
      newMin - new lower boundery
      newMax - new upper boundery
      Returns:
      x scaled from old to new.

    • pnpoly

      public static boolean pnpoly(int numVerts, double[] vertXs, double[] vertYs, double testX, double testY)
