Method Detail

setScale

public void setScale(double scale)

Description copied from class: OctaveGenerator

Sets the scale used for all coordinates passed to this generator.

This is the equivalent to setting each coordinate to the specified value.

Overrides:

setScale in class OctaveGenerator

Parameters:

scale - New value to scale each coordinate by

getWScale

public double getWScale()

Gets the scale used for each W-coordinates passed

Returns:

W scale

setWScale

public void setWScale(double scale)

Sets the scale used for each W-coordinates passed

Parameters:

scale - New W scale

noise

public double noise(double x,
                    double y,
                    double z,
                    double w,
                    double frequency,
                    double amplitude)

Generates noise for the 3D coordinates using the specified number of octaves and parameters

Parameters:

x - X-coordinate

y - Y-coordinate

z - Z-coordinate

w - W-coordinate

frequency - How much to alter the frequency by each octave

amplitude - How much to alter the amplitude by each octave

Returns:

Resulting noise
