Method Detail

intNoise

public static int intNoise(int x)

Fairly bad noise function. But it is predictable and quick. Good for testing.

linearInterpolate

public static float linearInterpolate(float a,
                                      float b,
                                      float x)

linear interpolation between two values.

Parameters:

a - start point

b - end point

x - value between 0 and 1 representing the distance from a to b you want a new point

cosineInterpolate

public static float cosineInterpolate(float a,
                                      float b,
                                      float x)

smother interpolation between two values.

Parameters:

a - start point

b - end point

x - value between 0 and 1 representing the distance from a to b you want a new point
