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

Value
This function is called for its side effects
Examples
