o turbulence2 
 public static double turbulence2(double x,
                                  double y,
                                  double octaves)
Compute turbulence using Perlin noise.

Parameters:
x - the x value
y - the y value
octaves - number of octaves of turbulence
Returns:
turbulence value at (x,y)
o noise1 
 public static double noise1(double x)
Compute 1-dimensional Perlin noise.

Parameters:
x - the x value
Returns:
noise value at x in the range -1..1
o noise2 
 public static double noise2(double x,
                             double y)
Compute 2-dimensional Perlin noise.

Parameters:
x - the x coordinate
y - the y coordinate
Returns:
noise value at (x,y)
o noise3 
 public double noise3(double x,
                      double y,
                      double z)
Compute 3-dimensional Perlin noise.

Parameters:
x - the x coordinate
y - the y coordinate
y - the y coordinate
Returns:
noise value at (x,y,z)
o findRange 
 public static double[] findRange(com.jhlabs.math.Function1D f,
                                  double minmax[])
Returns the minmimum and maximum of a number of random values of the given function. This is useful for making some stab at normalising the function.

o findRange 
 public static double[] findRange(com.jhlabs.math.Function2D f,
                                  double minmax[])
Returns the minmimum and maximum of a number of random values of the given function. This is useful for making some stab at normalising the function.
