AccelerateInterpolator

public AccelerateInterpolator(float factor)

Constructor

Parameters:

factor - Degree to which the animation should be eased. Seting factor to 1.0f produces a y=x^2 parabola. Increasing factor above 1.0f exaggerates the ease-in effect (i.e., it starts even slower and ends evens faster)

getInterpolation

public float getInterpolation(float input)

Description copied from interface: Interpolator

Maps a point on the timeline to a multiplier to be applied to the transformations of an animation.

Specified by:

getInterpolation in interface Interpolator

Parameters:

input - A value between 0 and 1.0 indicating our current point in the animation where 0 represents the start and 1.0 represents the end

Returns:

The interpolation value. This value can be more than 1.0 for Interpolators which overshoot their targets, or less than 0 for Interpolators that undershoot their targets.
