3D bear software needs an iphone to scan the QR code to download. . Specific tutorial: prepare two mobile phones (ipad is also acceptable), one of which must be Apple. 2: Apple's mobile phone scans the QR code below and downloads the software. 3: The other mobile phone saves these pictures. 4: Open the software and take pictures of the other mobile phone, and the three-dimensional bear will appear! Each picture of the bear is different ~ the effect of turning off the lights is even better! (As for the QR code and pictures, many people have sent them in Weibo ...)
