https://techcrunch.com/2018/05/30/google-builds-its-cross-platform-multiplayer-ar-tech-into-a-doodling-app/ > At Google I/O earlier this month, the company announced Cloud Anchors, a tool that shares 3D data captured by a user’s smartphone with the cloud and can match that data up with another user to create a shared AR experience where each person’s phone is seeing the same things in the same places. > Today, Google is rolling out Cloud Anchor functionality to its AR drawing app called Just a Line which it released a couple months ago. Just a Line is hardly a breakout hit for Google, but the simplistic app that lets users paint the 3D world with a white line offers a nice testbed for early AR functionality that’s just as experimental.
