Viro React

Viro React is a platform for developers to rapidly build augmented reality (AR) and virtual reality (VR) experiences. Developers write in React Native, and Viro runs their code natively across all mobile VR (including Google Daydream, Samsung Gear VR, and Google Cardboard for iOS and Android) and AR (iOS ARKit and Android ARCore) platforms. More info here.

This project contains the full source code for Viro React, and various sample Viro projects.

The platform is free to use with no limits on distribution.

To report bugs/issues with Viro platform, please file new issues on this repository.

Viro Bridge CI Pipeline

Instructions for running sample projects using Testbed app:

  1. Follow directions on our Quick start guide to setup dependencies for trying these sample projects with the Viro Media App.
  2. Clone the repo into your workspace with git: git clone https://github.com/viromedia/viro.git.
  3. Go into the code-samples directory.
  4. Run npm install from the root of this project.
  5. Run npm start from the root of this project.
  6. Open the Viro Media App, slide out the left panel and select "Enter Testbed".
  7. Type the entire ngrok URL output (xxxxxx.ngrok.io) at the top of the terminal into the text field and hit 'GO'
  8. You should now be in the application! Enjoy!

To rebuild the testbed app from source, please refere to the testbed repo here.

Instructions for running sample code as a stand alone project (with no Testbed app):

Tried the samples through our Testbed app and now want to try deploying sample code to your device as standalone apps? These quick steps below should get you started:

  1. Follow steps 1 - 4 from above (instructions for using with Testbed app)
  2. For Android, make sure you have downloaded and installed Android Studio from here to get required SDK and platform-tools for building android apps Make sure you have the required environment variables set - $ANDROID_HOME, and added platform-tools to $PATH variable. If not,
    export ANDROID_HOME=/YOUR_PATH_TO/Android/sdk
    export PATH=$ANDROID_HOME/platform-tools:$PATH
    export PATH=$ANDROID_HOME/tools:$PATH
    
    Build and launch android app by executing the following from the root of the project
    react-native run-android --variant=gvrDebug
    
  3. For iOS, in Xcode open ViroSample.xcworkspace in ios/ directory. Select the right "Team" for ViroSample and ViroSampleTest target under General -> Signing Hit play to build and launch the app on your iOS device

Changing Between Samples

  1. Open App.js in a text editor.
  2. For AR, set showARScene=true at line 44.
  3. For VR, Modify line 61: scene: scenes['360 Photo Tour'], to a scene defined in the scenes dictionary on line 30.
  4. Reload/restart the application.

Instructions for using a CI-built Viro React platform from Mainline:

You can also try the latest mainline build containing bleeding edge features and fixes. Please keep in mind that mainline builds may not be as stable as release builds. To do so, simply:

  1. Go to the Viro Actions Workflows for this project.
  2. You should see a list of "Viro Bridge CI Pipeline" workflows.
  3. Click on the latest successfully built workflow pipeline (should be a checkmark next to it).
  4. Download the latest built ViroReact.tgz artiface.
  5. Clone this repo into your workspace with git: git clone https://github.com/viromedia/viro.git.
  6. Go into the code-samples directory.
  7. Run npm install from the root of this project.
  8. Remove the ViroReact framework that was pulled down from the npm install (you are going to use the pre-built one).
  9. npm install ../path/to/your/downloadedArtifact.tgz

Instructions for manually building the Viro React platform:

Building iOS Viro React:

  1. Follow directions on our Quick start guide to setup dependencies.
  2. Clone the repo into your workspace with git: git clone https://github.com/viromedia/viro.git.
  3. Build our iOS renderer using build instructions outlined in our Virocore repo.
  4. Verify you see new files created in ios/dist folder.
  5. Install pods in ios/ folder:
    cd ios
    pod install
    
  6. Install node_modules in test folder:
    cd test
    npm install
    
  7. Install pods in the ViroExample folder:
    cd test/ios/ViroExample
    pod install
    
  8. Open ViroExample.xcworkspace in Xcode. (Make sure you open the .xcworkpace file, and not* the .xcodeproj file!)
  9. Select Product->Scheme. If you don't see a React scheme, hit Manage Schemes.... In the dialog box, add React scheme.
  10. Go through build configuration (Debug vs Release) for schemes React, ViroReact and ViroExample and ensure they are all either Release or Debug, depending on what you are trying to build.
  11. That's it! Now build React scheme for Generic iOS Device, followed by ViroReact scheme for the same target. Note:
    11.a If you want the ability to run on Simulator, 
         change target to any of the `iOS Simulator` targets instead of `Generic iOS Device`. 
    11.b If in your own app project setup, you prefer to include Viro React as a static library 
         rather than relying on `use_frameworks!` - build scheme `ViroReact_static_lib` 
         instead of `ViroReact` as mentioned above in step #11. 
    
  12. You should see a new file libViroReact.a at ios/dist/lib/libViroReact.a.
  13. To run Viro React tests, run ViroExample scheme on your plugged in iOS device.

Building Android Viro React:

  1. Under the viro directory, run ./prepareRelease.sh.
  2. Your android bridge should now be built under release.
  3. You should see a new file created at android/react_viro/react_viro-release.aar
  4. To build android release tests:
    $ cd test/android
    $ ./gradlew assembleGvrRelease
    
  5. Install app-gvr-release.apk from test/android/app/build/output/gvr/app-gvr-release.apk onto your plugged in Android device.

Bundling and using built iOS and Android into a single npm tar package:

  1. The ./prepareRelease.sh you ran above builds android react bridge and bundles both iOS and Android bridge into a react-viro-*.tgz file. * for current version from package.json file.
