Auto adjustment of orientation of a 3D model as it flies

// Add button to fire AH64

Sandcastle.addToolbarButton(‘Fire AGM-114’, function() {

//Seed the random number generator for repeatable results.


promise.then(function(dataSource) {


  //Load cmzl file

  var promise = Cesium.CzmlDataSource.load('/sjc/agmLaunch.czml');

  promise.then(function(dataSource) {


  //Get the array of entities

  var entities = dataSource.entities.add({

    orientation : new Cesium.VelocityOrientationProperty(position)





I have been building an app that shows a visual depiction of the flight path of a missile. I am almost done with my demo and have properly oriented the aircraft but I don’t understand how to change orientation of the missile as it flies. I saw some other people have said to use the Cesium.VelocityOrientationProperty function to modify the czml file my missile is in on the client side, this is what I have so far.
