react-native-gl-model-view
A <ModelView> component for react-native, allowing you to display and animate any Wavefront .OBJ 3D object. Realized with a native bridge to GLView for iOS and a native bridge to jPCT-AE for Android.
Main features:
- Display, rotate, scale and translate textured 3D models!
- Animate with blasting fast 60 fps by using the Animated API native driver
- Supports Wavefront .OBJ and GLEssentials model formats (iOS)
- Supports Wavefront .OBJ, Autodesk 3DS, Quake 2 MD2, ASC and GLEssentials model formats (Android)
- Supports all texture image formats supported by UIImage
Getting started
Since React Native 0.60 and higher, autolinking makes the installation process much simpler.
$ yarn add react-native-gl-model-view
# Update your pods (iOS)
$ cd ios
$ pod install
Using React Native Link (React Native 0.59 and lower)
Run react-native link react-native-gl-model-view after which you should be able to use this library on iOS and Android.
iOS Manual installation
$ yarn add react-native-gl-model-view
Afterwards add following lines to your Podfile:
pod 'React', :path => '../node_modules/react-native'
pod 'RNGLModelView', :path => '../node_modules/react-native-gl-model-view'
Android Manual installation
$ yarn add react-native-gl-model-view
Afterwards, add the following lines to the android/settings.gradle file:
include ':react-native-gl-model-view'
project(':react-native-gl-model-view').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-gl-model-view/android/app')
Finally, add the react-native-gl-model-view project as a dependency of the android/app/build.gradle file:
dependencies {
compile project(':react-native-gl-model-view')
...
}
Usage
Model and texture loading
iOS
To load a model on iOS, you need to put the file at the root of your Xcode project via the editor.
Android
To load a model on Android, you need to place the model in the android/app/src/main/assets folder. Create a new folder if it doesn't exist yet.
Static
import ModelView from 'react-native-gl-model-view';
<ModelView
model={{
uri: 'model.obj',
}}
texture={{
uri: 'texture.png',
}}
scale={0.01}
translateZ={-2}
rotateZ={270}
style={{flex: 1}}
/>
Animated
Make the <ModelView>'s native props animatable by wrapping the Animated API around it:
import ModelView from 'react-native-gl-model-view';
import { Animated, Easing } from 'react-native';
const AnimatedModelView = Animated.createAnimatedComponent(ModelView);
As this usage of the Animated API is kinda hacky, you must call the private __makeNative() method on all Animated.Values before using Animated.multiply and such.
constructor() {
this.state = {
zoom: new Animated.Value(0),
// ...
};
Object.keys(this.state).forEach(key =>
this.state[key] instanceof Animated.Value &&
this.state[key].__makeNative()
);
}
Now you can apply all the Animated API magic to the <AnimatedModelView>'s props.
render() {
<AnimatedModelView
...
animate={true}
translateZ={this.state.zoom}
/>
}
componentDidMount() {
Animated.timing(this.state.zoom, {
toValue: -2,
useNativeDriver: true,
duration: 2000,
easing: Easing.bounce
}).start();
}
