ARLightEstimate

Estimated scene lighting information associated with a captured video frame in an AR session.

Overview

If you render your own overlay graphics for the AR scene, you can use this information in shading algorithms to help make those graphics match the real-world lighting conditions of the scene captured by the camera. (The ARSCNView class automatically uses this information to configure SceneKit lighting.)
