Instance Property


The behavior ARKit uses for generating environment textures.


var environmentTexturing: ARWorldTrackingConfiguration.EnvironmentTexturing { get set }


Environment textures are cube-map textures that depict the view in all directions from a specific point in a scene. In 3D asset rendering, environment textures are the basis for image-based lighting algorithms where surfaces can realistically reflect light from their surroundings. ARKit can generate environment textures during an AR session using camera imagery, allowing SceneKit or a custom rendering engine to provide realistic image-based lighting for virtual objects in your AR experience.

To enable texture map generation for your configuration, change this property (from its default value of ARWorldTrackingConfiguration.EnvironmentTexturing.none):

In both cases, ARKit automatically generates environment textures as the session collects camera imagery. Use a delegate method such as session(_:didUpdate:) to find out when a texture is available, and access it from the anchor's environmentTexture property.

If you display AR content using ARSCNView and the automaticallyUpdatesLighting option, SceneKit automatically retrieves AREnvironmentProbeAnchor texture maps and uses them to light the scene.
