title: Cesium czml change orientation of 3d model (gltf/glb) along with position in time
body: <p>I have implemented a 3d model (cesium air) aircraft to move along a path. Its position is being changed based on time and the detailed data is available in the czml file under position attribute. However, I am not able to change the orientation of the aircraft along with path. The aircraft flies through the path but its heading , pitch and roll are constant. It does not pitch up with increase in height etc. How to implement the attitude changes using orientation attribute in the czml file or any other solution for the said problem?</p>
