Method Detail

interpolate

float interpolate(float fraction)

This function takes an input value between 0 and 1 and returns another value, also between 0 and 1. The purpose of the function is to define how time (represented as a (0-1) fraction of the duration of an animation) is altered to derive different value calculations during an animation.

Parameters:

fraction - a value between 0 and 1, representing the elapsed fraction of a time interval (either an entire animation cycle or an interval between two KeyFrames, depending on where this Interpolator is used)

Returns:

a value between 0 and 1. Values outside of this boundary may be clamped to the interval [0,1] and cause undefined results.
