Method Detail

clamp

public static float clamp(float v)

Clamps the value so the result is between 0.0 and 1.0.

This means that if the value is smaller than 0.0, this method will return 0.0. If the value is larger than 1.0, this method will return 1.0. Values within the range are returned unchanged.

Parameters:

v - the value to clamp

Returns:

a value between 0.0 and 1.0.

clamp

public static double clamp(double v)

Clamps the value so the result is between 0.0 and 1.0.

This means that if the value is smaller than 0.0, this method will return 0.0. If the value is larger than 1.0, this method will return 1.0. Values within the range are returned unchanged.

Parameters:

v - the value to clamp

Returns:

a value between 0.0 and 1.0.

clamp

public static float clamp(float v,
                          float min,
                          float max)

Clamps the value so the result is between the given minimum and maximum value.

This means that if the value is smaller than min, this method will return min. If the value is larger than max, this method will return max. Values within the range are returned unchanged.

Parameters:

v - the value to clamp

min - the minimum value

max - the maximum value

Returns:

a value between min and max.

clamp

public static double clamp(double v,
                           double min,
                           double max)

Clamps the value so the result is between the given minimum and maximum value.

This means that if the value is smaller than min, this method will return min. If the value is larger than max, this method will return max. Values within the range are returned unchanged.

Parameters:

v - the value to clamp

min - the minimum value

max - the maximum value

Returns:

a value between min and max.

snap

public static double snap(double v,
                          double distance,
                          double strength)

Round a value to the nearest "step".

Parameters:

v - The value to snap.

distance - The distance between steps.

strength - The strength of rounding. If 1 the values will always be on a step. If zero, the value is unchanged.

Returns:

The snapped value.

randomFromSeed

public static Random randomFromSeed(long seed)
