I want to find the distance between the iOS device (equipped with LiDAR) and the real-world object centred in the screen. Using that depth information, I want to scale an overlay object that spawns from a MARS image marker. I have looked at some ARFoundation documentation (Raycasts) etc. but could not yet figure out how to just calculate the distance using the LiDAR. Perhaps through the depth image feature? Any tips please?
