Method and apparatus for chaining two or more tweens to provide non-linear multimedia effects
An improved method for generating non-linear multimedia effects by employing two or more tweens. Specifically, a second tween mapping is chained to a first tween mapping. A first time signal is received. The first tween is employed to map the first time signal into a second time signal. The second tween mapping is employed to map the second time signal into an output that varies in a non-linear fashion with respect to the first time signal.
