How to use

See https://github.com/sqvcnet/react-native-libvr-demo and https://github.com/sqvcnet/react-native-libvr for detailed usages

You can also run the simple demo.xcodeproj to take the first glance

Notice: If you want to use this project in your own iOS project, remember to add "CoreMedia.framework, AudioToolbox.framework, VideoToolbox.framework, libz.dylib, libc++.dylib, GLKit.framework" in "Link Binary with Libraries" of project "Build Phrases". In order to add libz.dylib and libc++.dylib, you may be need to "Add Other" then press "Shift+Command+G" then input "/usr/lib" then find them, since the *.tbd cannot work.

For iOS

You should add NSMotionUsageDescription(Privacy - Motion Usage Description) in Info.plist, see https://developer.apple.com/documentation/coremotion

Important

The OpenGL ES code may run faster or slower in simulator than on an actual device. Always profile and optimize your drawing code on a real device, and never assume that Simulator reflects real-world performance. See https://developer.apple.com/library/content/documentation/OpenGLES/Conceptual/OpenGLESHardwarePlatformGuide_iOS/OpenGLESiniOSSimulator/OpenGLESiniOSSimulator.html for more details.
