Use case

Visualize movement through a 3D landscape.

How to use the sample

Animation Controls:

Select a mission -- select a flight path
Play/Pause -- toggles playing and stopping the animation
Follow/Don't follow -- toggles the camera's free cam mode and follow
Mission progress -- shows how far along the route the plane is. Slide to change keyframe in animation
Flight speed -- controls speed of animation

How it works

Create a GraphicsOverlay and add it to the SceneView.
Create a ModelSceneSymbol object.
Create a Graphic object and set its geometry to a Point.
Set the ModelSceneSymbol object to the graphic.
Add heading, pitch, and roll attributes to the graphic. Get the attributes from the graphic with Graphic.attributes.
Create a SimpleRenderer object and set its expression properties.
Add graphic and a renderer to the graphics overlay.
Create a OrbitGeoElementCameraController which is set to target the graphic.
Assign the camera controller to the SceneView.
Update the graphic's location, heading, pitch, and roll.
