Interface Interpolation

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface Interpolation
Interpolation methods. Some of these were converted from Flash ActionScript implementations explained in the article http://gizma.com/easing/.

The JavaDoc for each interpolation method includes a graphical example in ASCII art to visualize the interpolation curve.

  • Method Details

    • interpolate

      float interpolate(float x0, float x1, float delta)
      Returns the interpolated value between x0 and x1. The value of delta is a number between 0 and 1 describing how much of the animation has been completed.
