This sample demonstrates environment probes, a feature which attempts to generate a 3D texture from the real environment and applies it to reflection probes in the scene. The scene includes several spheres which start out completely black, but will change to shiny spheres which reflect the real environment when possible.
Note: environment probes are currently only supported on iOS.
## ARWorldMap
An `ARWorldMap` is an ARKit-specific feature which lets you save a scanned area. ARKit can optionally relocalize to a saved world map at a later time. This can be used to synchronize multiple devices to a common space, or for curated experiences specific to a location, such as a museum exhibition or other special installation. Read more about world maps [here](https://developer.apple.com/documentation/arkit/arworldmap). A world map will store most types of trackables, such as reference points and planes.
