An OrbitGeoElementCameraController follows a graphic while the graphic's position and rotation are animated.

Image of animate 3D graphic

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

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