values.
Each index into the array is treated as a separate value to interpolate. For example,
evaluating {100, 200}
and {300, 400}
will interpolate the value at
the first index between 100 and 300 and the value at the second index value between 200 and 400.Constructor and Description |

FloatArrayEvaluator()
Create a FloatArrayEvaluator that does not reuse the animated value.

FloatArrayEvaluator(float[] reuseArray)
Create a FloatArrayEvaluator that reuses
reuseArray for every evaluate() call. |
