|
|
|
<div id="docs"><p>This example shows how to use <b>postrender</b> and <b>vectorContext</b> to animate flights. A great circle arc between two airports is calculated using <a href="https://github.com/springmeyer/arc.js">arc.js</a> and then the flight paths are animated with <b>postrender</b>. The flight data is provided by <a href="https://openflights.org/data.html">OpenFlights</a> (a simplified data set from the <a href="https://docs.mapbox.com/mapbox.js/example/v1.0.0/animating-flight-paths/"> Mapbox.js documentation</a> is used).</p>
