I want to make a flight path in Cesium just like this one  
[http://www.senchalabs.org/philogl/PhiloGL/examples/worldFlights/](http://www.senchalabs.org/philogl/PhiloGL/examples/worldFlights/)  
If i use the polyline, the routes will stuck on the ground, I want to make flight path in air, Could you show me the code about the drawing line function. Thank you!

You’ll want to use [Path](http://cesiumjs.org/Cesium/Build/Documentation/PathGraphics.html)rather than Polyline. Here’s the idea using an [Entity](http://cesiumjs.org/Cesium/Build/Documentation/Entity.html).

var viewer = new Cesium.Viewer(‘cesiumContainer’);

viewer.clock.startTime = Cesium.JulianDate.fromIso8601(“2014-03-14T00:00:00.000Z”);

viewer.clock.stopTime = Cesium.JulianDate.fromIso8601(“2014-03-15T00:00:00.000Z”);

viewer.clock.currentTime = Cesium.JulianDate.fromIso8601(“2014-03-14T00:00:00.000Z”);

viewer.clock.clockRange = Cesium.ClockRange.LOOP\_STOP;

var entities = viewer.entities;

var flights = entities.add(new Cesium.Entity());

var aircraftPositions = new Cesium.SampledPositionProperty();

aircraftPositions.addSample(“2014-03-14T16:00:00.000”, Cesium.Cartesian3.fromDegrees(-80.000, 28.400, 0.000));

var aircraft = entities.add({

parent: flights,

name: “XYX1308”,

description: “A flight roughly from Florida to Ireland.”,

position: aircraftPositions,

orientation: new Cesium.VelocityOrientationProperty(aircraftPositions),

path: {

leadTime: 86400.0,

trailTime: 86400.0,

width: 2.0,

material: Cesium.Color.DODGERBLUE

}

});

``

I’ve also attached a full Sandcastle example.

Hi Scott,

I have to do the same thing, but I don’t want to use viewer. As I am using trackingView of earth. Could you help me. Please.

Thank you in advance.

Best Regards,

Lalit
