Animate 3D graphic

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

Use case

Visualize movement through a 3D landscape.

How to use the sample

Tap the buttons on the bottom toolbar to adjust the settings for the animation:

• Mission: change the flight path, speed, and view progress
• Play/Pause: toggle the animation
• Camera: change the camera distance, heading, pitch, and other camera properties.

How it works

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