Method Detail

normalizeKnots

public static void normalizeKnots(double[] knots,
                  double ustart,
                  double uend)

createKnots

public static double[] createKnots(int degree,
                   int num,
                   boolean closed)

createKnots

public static double[] createKnots(int degree,
                   int num)
