Web er brings ar and vr to the browser. The API is supported by amazon and google so immersive experiences that are only accessible through a browser will be a big hit in the near future. Web er is compatible with oculus headsets including the oculus quest 2. The chrome android browser supports the API for ar, augmented reality and vr, virtual reality experiences. Web er does not harness the sensors of a mobile device, but creates a defined way to use this data. Three.js is the best web gl library to visualize 3D content. This well-known open source library is used by many people around the world and is supported by many developers. Three.js is currently at version 118. It is a robust and production-ready library. The library recently added web er support. Developers now have the ability to create immersive experiences. This course will show you how easy it is to use three.js to create vr and ar experiences. You will need to be familiar with JavaScript coding in order to get the most out of the course. There are no other prerequisites. The course is divided into 10 modules. Introduction: I will introduce web er's history, give you a brief primer for those who are new to 3D concepts, and show you the three.js website as well as some web er examples. A three.js primer - this is for three.js beginners to get you up to speed with the library. We will be introducing web er using three.js. We will examine your development environment and create our first web er samples. Module 4: creating immersive experiences with complex assets using three.js. Most things you create will require complex assets. We'll be looking at your development environment and creating our first web er examples.
