<h1><a href="../index.html">lib.</a><a href="index.html">pixi.</a>Flip Effect</h1>
|
2019-10-02 11:51:23 +02:00
|
|
|
<p>
|
|
|
|
|
The flip effect, which simulates a flip between a front and back view of an object by means of a 3D
|
|
|
|
|
rotation, is an interaction between a PIXI scatter object and a DOM Flip effect. The PIXI scatter is used as
|
|
|
|
|
the source for the front view of the DOM Flip which is created on demand if the user clicks the Info Button
|
|
|
|
|
which is added to the PIXI scatter by the FlipEffect wrapper.
|
|
|
|
|
</p>
|
|
|
|
|
<p>
|
|
|
|
|
For the user it simply looks like a single flipping card, but in terms of UI elements, the following levels
|
|
|
|
|
are mixed:
|
|
|
|
|
</p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li>A PIXI scatter object, typically a zoomable image, as the default front view.</li>
|
|
|
|
|
<li>A special button (typically an info button), which triggers the animation.</li>
|
|
|
|
|
<li>
|
|
|
|
|
A DOM based animation which works on a DOM clone of the PIXI scatter and a DOM representation of the
|
|
|
|
|
back card. The PIXI scatter is hidden in the meanwhile.
|
|
|
|
|
</li>
|
|
|
|
|
<li>If the back card is closed, the DOM nodes are removed and the PIXI scatter is shown again.</li>
|
|
|
|
|
</ul>
