Navigate a scene view
You can navigate a scene view (a 3D map):
- Using built-in navigation (described on this page), such as panning, zooming, and changing pitch
- By programmatically changing camera position
The scene view has a number of built-in gestures that allow you to navigate a scene (3D) using touch screen, mouse, or keyboard.
Basic navigation for scene views is the same as navigation for map views:
|Zoom in||Two finger pinch open |
Single finger double-tap
|Zoom out||Two finger pinch close |
Two finger single-tap
|Continuous zoom in / out||Single finger double-tap, ending in a vertical up/down drag|
|Move/Pan||Single finger drag or flick|
|Rotate the scene||Two finger rotate|
Scene views have additional navigation not found in map views:
|Tilt the scene||Three finger drag|
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.
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.
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 meters above sea level
- For heading, use 295 degrees
- For pitch, use 71 degrees
- For roll, use 0 degrees
let snowdonCamera = AGSCamera(latitude: 53.06, longitude: -4.04, altitude: 1289, heading: 295, pitch: 71, roll: 0)
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.
