Rebound is a Java library from Facebook that models spring dynamics for creating natural, physics-based animations. It is a lightweight building block for driving UI animations like pagers, toggles, and scrollers rather than a general-purpose physics engine.
Use cases
- add spring physics to android animations
- create natural bounce effects in ui transitions
- build springy pagers and toggles
- implement physics-based scrolling in a java app
- replace linear interpolators with realistic motion
When to choose
- you want lightweight spring dynamics without a full physics engine
- you are building android or jvm ui animations that should feel natural
- you need a simple building block for custom animated components
When to avoid
- you need a general-purpose physics simulation library
- you want spring animations for the web (use rebound-js instead)
- you need actively maintained software with recent releases
