SDK
Framework
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.)
var ambientThe estimated intensity, in lumens, of ambient light throughout the scene.
var ambientThe estimated color temperature, in degrees Kelvin, of ambient light throughout the scene.
class ARFrameA video image, with position-tracking information, captured as part of an AR session.
