Because of the presence of Pokémon Go, lots of people start to discuss the possibility of AR (augmented reality) on the Web. Thanks for Jerome Etienne's slides , it brings me some idea to make this AR demo. First of all, it is based on three.js and js-aruco . three.js is a WebGL framework that helps us construct and load 3D models. js-aruco is Javascript version of ArUco that is a minimal library for Augmented Reality applications based on OpenCV. These two project make it is possible to implement a Web AR proof of concept. Then, I would like to introduce how to implement this demo. First, we need to use navigator .getUserMedia to give us the video stream from our webcam. This function is not supported on all browser vendors. Please take a look at the status. http://caniuse.com/#feat=stream navigator.getUserMedia = ( navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia ||
