## Discussion

Discussion Implement this method if you provide your own display for rendering an AR experience. The provided ARFrame object contains the latest image captured from the device camera, which you can render as a scene background, as well as information about camera parameters and anchor transforms you can use for rendering virtual content on top of the camera image.
