Class EasingCurves

  • public final class EasingCurves
extends java.lang.Object
    This class provides static functions for the most common easing curves used around the world and on most design guides, such as Google's Material Design [1] In curves are used to approach a value at maximum speed Out curves are used to approach a value at zero speed InOut curves mixes the in and out curves, creating a S-shaped curve Elastic curves extrapolate both begin and end values a little for a visually pleasant effect Bounce curves arrive at the end value multiple times before settling in, creating a bouncy effect. Illustrations of these curves can be seen at [2] For a reference implementation, see [3] All easing curves take 4 parameters: the begin and end values, the animation duration and the position we want to evaluate on the curve References: [1] https://material.io/guidelines/motion/duration-easing.html [2] http://easings.net [3] https://github.com/daimajia/AnimationEasingFunctions
