Getting Started with React VR

By: John Gwinner

Overview of this book

This book takes you on a journey to create intuitive and interactive Virtual Reality experiences by creating your first VR application using React VR 2.0.0. It starts by getting you up to speed with Virtual Reality (VR) and React VR components. It teaches you what Virtual Reality (VR) really is, why it works, how to describe 3D objects, the installation of Node.js (version 9.2.0) and WebVR browser. You will learn 3D polygon modeling, texturing, animating virtual objects and adding sound to your VR world. You will also discover ways to extend React VR with new features and native Three.js. You will learn how to include existing high-performance web code into your VR app. This book will also take you through upgrading and publishing your app. By the end of this book, you'll have a deep knowledge of Virtual Reality and a full-fledged working VR app to add to your profile!

Graphics libraries — OpenGL and WebGL

This section covers general 3D programming, but some discussion of different things is in order.

OpenGL is a standard for displaying graphics. Without getting into PC versus Workstation politics (ancient history now), it was a standard that a workstation vendor (SGI) pioneered to standardize computer graphics and the ability for programs to display graphics.

There are other APIs, such as DirectX, which was backed by Microsoft and many PC game developers, CAD software, and other PC computer graphics.

OpenGL is not, strictly speaking, open source; yet the software can be used without royalty payments and is documented and freely available (to be fair, so is DirectX).

Basically, OpenGL is a way for software to display graphics. Software, in this case, usually means C++ (or other languages that can call native libraries and O/S utilities).

Vulkan is more or less an intended successor to OpenGL. It is on a lower level than OpenGL, and offers more ability to perform...
