![]() ![]() The three components will each have their own file, so let’s create a components folder to contain these files. a UI component, which builds a UI out of four Button components.a Button component, which creates a VR button to swap the images.a Canvas component, which holds the code for the full-sphere images.We want our project to have three components: We’ll put the equirectangular images and the button graphics in this folder. This folder should contain all assets used in the application. Currently, the file contains the whole source code of React VR’s default scene, as we already saw in the browser. ![]() This is the entry point of the application. The most important files and folders scaffolded by the React VR CLI are: If you see a black and white room with stairs, pillars, and a “hello” text plane, everything’s correct. To start a local development server, we’ll run an npm script and browse to in Chrome. React-vr init GDVR_REACTVR_SITEPOINT_GALLERY Then create a new React VR project with all its dependencies in a new folder called GDVR_REACTVR_SITEPOINT_GALLERY: npm install -g react-vr-cli Let’s start by installing the React VR CLI tool. Here’s a good summary of browsers currently supporting WebVR features. But the library, as well as the API, are still under development, so the support may not be reliable. In theory, any mobile browser capable of WebVR should be able to render our app in a stereoscopic way for the usage with GearVR, Google Cardboard, or even Google Daydream. To check if the stereoscopic rendering for VR devices works, we’re using a Samsung phone with Gear VR. Last but not least, we’ll take a look at how animations work with React VR by adding a simple button transition.įor development, we’re using a browser like Chrome on the desktop. You can download the equirectangular images as well as the button graphics here. The gallery will have four buttons to swap the images, which will work with the mouse and/or VR headset. For this, we’ll use four equirectangular photos, which I shot at React Conf 2017 with my Theta S camera. In this article, we want to use React VR to build a viewer for spherical images. To simplify the process of creating a WebVR scene, React VR has built-in support for 3D meshes, lights, videos, 3D shapes, or spherical images. This means that we’re able to use JSX tags, React Native components, like or, or React Native concepts, like the flexbox layout. React VR is built on the WebGL library three.js and the React Native framework. You may compare React VR with A-Frame by Mozilla, but instead of writing HTML, with React VR we’re using JavaScript to create a WebVR scene. ![]() React VR is a JavaScript library by Facebook that reduces the effort of creating a WebVR application. ![]()
