Developed by drew castle is not the usual way.
The network has a huge number of examples of experiments with ARKit, from jungle to garage to landing the Fa lcon 9 into the pool. One recent video shows how the developer draws in the air using the pen instead of your finger. Through the screen image looks like it was done in simple ink. When the user has finished drawing, the app offers to turn it into a 3D model.
The technology, which uses the developer, combines the ARKit and a new iOS app 11 Vision that allows you to track moving objects.
Apple first introduced the ARKit in June of this year. iOS 11 will be released this fall, so we see a lot of apps that use the capabilities of augmented reality. Meanwhile, the network spread only Amateur projects, but they are sometimes very funny.
