Navigate scene views

You can navigate scene views (ArcGISSceneView or ArcGISLocalSceneView) by:

• Using built-in navigation, such as panning, zooming, and changing pitch.
• By programmatically changing camera position.

Built-in navigation

Scene views have a number of built-in gestures that allow you to navigate a scene.

Basic navigation

Navigation for scene views is essentially the same as the navigation for a map view. Navigation in a scene view moves the position of a camera in 3D space and therefore has some subtle differences. The following table summarizes the built-in navigation capabilities of the ArcGISSceneView and ArcGISLocalSceneView widgets.

Advanced navigation

Scene views have additional navigation not found in a map view:

Programmatically change camera position

Your applications can programmatically navigate a 3D scene by creating a new camera and setting it to the view you are working with. A camera defines the location from which you are viewing the scene.

The camera is shown in this image for illustration purposes; when you set camera settings (location, pitch), think of the camera class as a real-life camera you're adjusting the position of.

Set the camera

For example, to point the camera to toward the Snowdon mountainside, use these values:

• For 3D location, use 53.06 latitude, -4.04 longitude, 1289 meters above sea level
• For heading, use 295 degrees
• For pitch, use 71 degrees
• For roll, use 0 degrees

// Set the camera to point at the Snowdon mountainside.
final snowdonCamera = Camera.withLatLong(latitude: 53.06, longitude: -4.04, altitude: 1289, heading: 295, pitch: 71, roll: 0);

You now have a new camera to apply to the view. You can apply it immediately using setViewpointCamera, as shown in the code below for an ArcGISSceneView, or the camera can be animated to the new position using one of the asynchronous methods.
