LibNoise JavaScript parameters

How do you initialise parameters for 3d Perlin noise from libnoise in JavaScript?

I can initialise the 3d Perlin noise

         var sponge=new Perlin();    
         var crd : float= sponge.Noise( vtxx * 4,vtxy * 4,vtxz * 4);

but they are randomised across tiles of terrain I don't know how to control the parameters such as offset and resolution etc. i.e:

             private Noise2D m_noiseMap = null;
         private Texture2D[] m_textures = new Texture2D[3];
         public int resolution = 64; 
 .......
 this.m_noiseMap = new Noise2D(resolution, resolution, moduleBase);
             this.m_noiseMap.GeneratePlanar(
             offset + -1 , 
             offset + offset + 1 , 
             offset + -1 ,
             offset + 1);

I am checking out about mixing 3d sponge functions with 2d terrains it's really fun. if you could tell me I will tell you example of this kind of formula:)
