Method Detail

same

public static boolean same(float a,
                           float b)

Returns:

true if the two values are equal.

diff

public static boolean diff(float a,
                           float b)

Returns:

true if the two values are different.

zero

Euclidean distance between points (x1,y1,z1) and (x2,y2,z2).

distance

public static float distance(float x1,
                             float y1,
                             float z1,
                             float rx1,

lerp

public static final float lerp(float start,
                               float stop,
                               float amt)

Calculates a number between two numbers at a specific increment. The amt parameter is the amount to interpolate between the two values where 0.0 equal to the first point, 0.1 is very near the first point, 0.5 is half-way in between, etc.
