Generates a gradient-coherent-noise value from the coordinates of a
three-dimensional input value.
@param x The @a x coordinate of the input value.
@param y The @a y coordinate of the input value.
@param z The @a z coordinate of the input value.
@param seed The random number seed.
@param noiseQuality The quality of the coherent-noise.
@returns The generated gradient-coherent-noise value.
The return value ranges from -1.0 to +1.0.
For an explanation of the difference between <i>gradient</i> noise and
<i>value</i> noise, see the comments for the GradientNoise3D() function.
