an implicit function that implements Perlin noise
vtkPerlinNoise computes a Perlin noise field as an implicit function. vtkPerlinNoise is a concrete implementation of vtkImplicitFunction. Perlin noise, originally described by Ken Perlin, is a non-periodic and continuous noise function useful for modeling real-world objects.
The amplitude and frequency of the noise pattern are adjustable. This implementation of Perlin noise is derived closely from Greg Ward's version in Graphics Gems II.

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Set/get the phase of the noise function. This parameter can be used to shift the noise function within space (perhaps to avoid a beat with a noise pattern at another scale). Phase tends to repeat about every unit, so a phase of 0.5 is a half-cycle shift.

Set/get the amplitude of the noise function. Amplitude can be negative. The noise function varies randomly between -|Amplitude| and |Amplitude|. Therefore the range of values is 2*|Amplitude| large. The initial amplitude is 1.
