Animate3DGraphic

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

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.
