Constructor Detail

SpringTransitionAnimator

public SpringTransitionAnimator(double tension,
                                double friction)

Create spring-driven animator with given tension and friction values. Spring physics implementation is taken from Rebound library and we recommend to use demo provided at https://facebookarchive.github.io/rebound to have a better sense of how friction and tension values work together.

SpringTransitionAnimator

public SpringTransitionAnimator(SpringConfig springConfig)
