Display local scene | ArcGIS Maps SDK for Swift

View on GitHub

Display a local scene with a topographic surface and 3D scene layer clipped to a local area.

Use case

A LocalSceneView is a user interface that displays 3D basemaps and layer content described in a Scene with a local Scene.ViewingMode.

Unlike a global scene, which is drawn on a globe using a geographic coordinate system, a local scene is drawn on a flat surface and supports projected coordinate systems. They are generally used to view local data and are often clipped to a specific area of interest. Currently, LocalSceneView cannot display data provided by a global scene, and SceneView cannot display data provided by a local scene.

The LocalSceneView displays the clipped area of the local scene, supports user interactions such as pan and zoom, and provides access to the underlying scene data.

How to use the sample

This sample displays a local scene clipped to an extent. Pan and zoom to explore the scene.

How it works

Create a local scene object with the Scene(viewingMode:basemapStyle:) constructor.
Create an ArcGISTiledElevationSource object and add it to the local scene's base surface.
Create an ArcGISSceneLayer and add it to the local scene's operational layers.
Create an Envelope and set it to the scene.clippingArea, then enable clipping by setting scene.clippingIsEnabled to true.
Set the initial viewpoint for the local scene.
Create a LocalSceneView instance with the scene.

About the data

The scene layer in this sample shows 3D extruded rooftop outlines of buildings on the Victoria University campus and surrounding vicinity in Wellington, New Zealand.
