Samples noise for a column at startNoiseX + localNoiseX, startNoiseZ + localNoiseZ. The startNoise and localNoise values should be added to produce the actual noise coordinate; they are kept separate for calculating accurate Beta/PE generation.

                                                 int localNoiseZ)

Samples the scale and depth values at startNoiseX + localNoiseX, startNoiseZ + localNoiseZ. The startNoise and localNoise values should be added to produce the actual noise coordinate; they are kept separate for calculating accurate Beta/PE generation.

Parameters:

Samples the noise offset at the given noise y-coordinate.

Parameters:
