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!

Importing materials

At the same time, we can use all the capabilities that React VR offers with regard to materials. The MTL file, unfortunately, doesn't always have the values possible. If you are using a modern material, that has base color, bump map or normal map, height, specular (shinyness), or metallic (similar to shinyness) maps, I've found that you may need to just hand edit the MTL file.

You would think with the wealth of computer graphics programs out there, that we wouldn't be at this point. Unfortunately, different rendering systems, especially nodal based ones, are too sophisticated for an OBJ exporter to really understand; as a result, typically most MTL files (materials) that go along with an OBJ file have only the base color as a texture map.

If you are using a program such as Quixel or Substance Designer, most Physically Based Rendering (PBR) materials consist of most of the following texture maps (images), which are also supported by the OBJ file format:

  • Base color: This is...
