Generates an integer-noise value from the coordinates of a three-dimensional input value.

@param x The integer @a x coordinate of the input value.
@param y The integer @a y coordinate of the input value.
@param z The integer @a z coordinate of the input value.
@param seed A random number seed.
@return The generated integer-noise value.
<p/>
The return value ranges from 0 to 2147483647.
<p/>
A noise function differs from a random-number generator because it always returns the same output value if the same input value is passed to it.
Generates an integer - noise value from the coordinates of a three - dimensional input value .
