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.
