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
- Create a
GraphicsOverlay
and add it to theSceneView
. - Create a
ModelSceneSymbol
object. - Create a
Graphic
object and set its geometry to aPoint
. - 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.
