/**
* Interface for - basically 3D - noise generation algorithms, based on the
* book: Texturing & Modeling - A Procedural Approach
*
* The main concept is to look at noise as a basis for generating fractals.
* Basis can be anything, like a simple:
*
* <code>
* float value(float x, float y, float z) {
* return 0; // a flat noise with 0 value everywhere
* }
* </code>
*
* or a more complex perlin noise ({@link ImprovedNoise}
*
* Fractals use these functions to generate a more complex result based on some
* frequency, roughness, etc values.
*
* Fractals themselves are implementing the Basis interface as well, opening
* an infinite range of results.
