How to easily create VR and AR apps that work in the browser
How to use the ThreeJS library to create these apps
How to handle controllers
How to replace the controllers with custom models
How to create architectural walk-throughs, games and training apps.
How to add an in world UI
Developing AR apps that support real world hit testing
Learn game VR techniques such as teleporting and interacting with models in the scene using controllers.

Requirements
An intermediate level JavaScript ability is assumed

Description
WebXR brings both VR and AR to the browser. The API has the massive forces of Google and Amazon behind it so it looks like immersive experiences, using only a browser, are going to make a huge impact in the near future. WebXR works great in the Oculus headsets and the Chrome Android browser is already supporting the API for both AR and VR experiences. But WebXR only harnesses the sensors on a mobile device and creates an agreed definition of how to use this data. To actually visualise 3D content you need a WebGL library and there is no better one to use than Three.JS. This mature Open Source library has many users around the globe and is supported by many developers. Three.JS is at version 118 at the time of writing and is a robust, production ready library. Recently WebXR support was added to the library. Making it easy for developers to create immersive experiences.

In this course you’ll learn how easy it is, using Three.JS, to create VR and AR experiences. To get the best from the course you will need to be comfortable with JavaScript coding. No other prerequisites are required.

The course is split into 10 sections.

Introduction – I introduce the history of WebXR, give you a basic primer for those of you new to 3D concepts and show you the Three.JS website and the WebXR examples.

A Three.JS Primer – is for Three.JS novices to bring you up to speed on the library.

An introduction to WebXR using Three.JS – we look in earnest at your development environment and create our first WebXR examples.

Using complex assets with Three.JS – most things you create for immersive experiences will need complex assets and sourcing, editing, loading and working with them is the subject of section 4.

The WebXR API – gives a review of the WebXR API.

Creating an Architectural Walk-Through – in section 6 we start to create real world examples of immersive content with an architectural walk-through.

Placing a Product in a Room – WebXR lends itself to showing real products in a person’s home and that is the topic for section 7.

Using WebXR for games – VR is perfect for games and we look at the basic ingredients of a game using WebXR in this section.

Using WebXR for training – covers the important topic of using VR for training.

Conclusion – we look at some WebXR examples to inspire you and review what you’ve learnt.

The only tools you’ll need are a code editor, in the course I use Brackets, freely available online. The course includes comprehensive resources and code examples. Each code example comes with two versions, one for you to code along with and another that is complete in case you hit a problem. I show you how to use github to host your development work on a secure server so you can easily test your work on a headset, such as an Oculus Quest

Who this course is for
Anyone interested in harnessing the latest WebXR API, to create VR and AR experiences that work in the browser without additional installation requirements.
