<h1>ol-ext: OL3 feature animation</h1>
</a>
<p class="info">
<i>ol.featureAnimation</i> provides animations to animate features on an OL3 map.
Animation can be chained.
<br />
Style with a zIndex of -1 are viewed as shadows and animated on the ground (drop or throw animation).
<br />
They are used with <i>animateFeature</i> function on <i>ol.layer.Vector</i> or <i>ol.Map</i>.
<br />
The animation is rendered in a postcompose frame.
