Navigate a scene view

You can navigate a scene view (a 3D map):

Built-in navigation

The scene view has a number of built-in gestures that allow you to navigate a scene (3D) using the iOS device. The tables below defines these gestures:

Programmatically change camera position

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

Camera position for a scene view

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

Set the camera

For example, to point the camera to toward the Snowdon mountainside, as shown in the following code snippet and image, use these values:

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

let snowdonCamera = AGSCamera(latitude: 53.06, longitude: -4.04, altitude: 1289, heading: 295, pitch: 71, roll: 0)

Surface elevation applied to a scene

Now you have a new camera you can apply to your scene view. You can apply it immediately using setViewpointCamera as shown in the code below, or the camera can be animated to the new position using one of the asynchronous methods.

self.sceneView.setViewpointCamera(snowdonCamera)
