Well, it doesn't seem to me that Apple has backed this new technology with any significant app that makes use of it.
And I don't see any serious app in the apple store that makes use of lidar either.
Edit: I forgot one super cool use of measure. Let's say you have a basement with an open ceiling. You can use the measure app to, say, measure a pipe. Then, when you walk upstairs, you can still see the pipe in 3D. So you can then understand just exactly under the floor where the pipe is. Very useful for things like pipes and electric wires.
That is really interesting. What app/service did you use to do this?
Any app used on half their billboards (Shot on iPhone 13 pro) and featured on the Lock Screen seems “significant” to me. :)
Other uses of LIDAR (measurement/data collection, AR, photography) are also likely to become more popular over time.
Turning the question round - why take photos of things? A 3D scan isn't that different. It's a way to capture a memory and to show things to other people. It's so quick to capture something that sometimes I just do it on a whim when I find something interesting.
I'd like to make an art piece out of them at some point but I'm still waiting for the right inspiration to come along.
