display_ease: Display an easing function

In tweenr: Interpolate Data for Smooth Animations

Display an easing function

Description

This simple helper lets you explore how the different easing functions govern the interpolation of data.

Usage

display_ease(ease)

Arguments

ease	The name of the easing function to display (see details)

Details

How transitions proceed between states are defined by an easing function. The easing function converts the parameterized progression from one state to the next to a new number between 0 and 1. linear easing is equivalent to an identity function that returns the input unchanged. In addition there are a range of additional easers available, each with three modifiers.

Easing modifiers:

-in

The easing function is applied as-is

-out

The easing function is applied in reverse

-in-out

The first half of the transition it is applied as-is, while in the last half it is reversed

Easing functions

quadratic

Models a power-of-2 function

cubic

Models a power-of-3 function

quartic

Models a power-of-4 function

quintic

Models a power-of-5 function

sine

Models a sine function

circular

Models a pi/2 circle arc

exponential

Models an exponential function

elastic

Models an elastic release of energy

back

Models a pullback and relase

bounce

Models the bouncing of a ball

In addition to this function a good animated explanation can be found here.

Value

This function is called for its side effects

Examples

# The default - identity
display_ease('linear')

# A more fancy easer
display_ease('elastic-in')
