<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.
