Abstract
An animation system is described herein that uses a transfer function on the progress of an animation that realistically simulates a bounce behavior. The transfer function maps normalized time and allows a user to specify both a number of bounces and a bounciness factor. Given a normalized time input, the animation system maps the time input onto a unit space where a single unit is the duration of the first bounce. In this coordinate space, the system can find the corresponding bounce and compute the start unit and end unit of this bounce. The system projects the start and end units back onto a normalized time scale and fits these points to a quadratic curve. The quadratic curve can be directly evaluated at the normalized time input to produce a particular output.
