react-native-3d-model-view

A React Native view for displaying .obj, .dae and .scn models either on screen or in AR (iOS devices with A9 or later processors only).

Example Project: https://github.com/BonnierNews/react-native-3d-model-view/tree/master/example

Getting started

$ yarn add react-native-3d-model-view

and then

$ react-native link react-native-3d-model-view

The lib also have peer dependencies of react-native-zip-archive, rn-fetch-blob and react-native-fs. Make sure that you yarn add and react-native link them to.

Swift

The ARModelView is written in Swift. So you need to add Swift to your project:

1. Add Swift 4.2 in your Xcode Build Settings (Support for Swift 3 is deprecated. If you still want to use Swift 3, use release 1.1.17)
2. Add a Empty.swift to your Xcode project (see example project for reference).

Usage

Model view

import ModelView from 'react-native-3d-model-view'

<ModelView
  source={{ zip: 'https://github.com/BonnierNews/react-native-3d-model-view/blob/master/example/obj/Hamburger.zip?raw=true' }}
  onLoadModelStart={this.onLoadModelStart}
  onLoadModelSuccess={this.onLoadModelSuccess}
  onLoadModelError={this.onLoadModelError} />

AR Model view

import ARModelView, { ModelTypes } from 'react-native-3d-model-view'

<ARModelView
  source={{ zip: 'https://github.com/BonnierNews/react-native-3d-model-view/blob/master/example/obj/Hamburger.zip?raw=true' }}
  onLoadModelStart={this.onLoadModelStart}
  onLoadModelSuccess={this.onLoadModelSuccess}
  onLoadModelError={this.onLoadModelError}
  onStart={this.onStart}
  onSurfaceFound={this.onSurfaceFound}
  onSurfaceLost={this.onSurfaceLost}
  onSessionInterupted={this.onSessionInterupted}
  onSessionInteruptedEnded={this.onSessionInteruptedEnded}
  onPlaceObjectSuccess={this.onPlaceObjectSuccess}
  onPlaceObjectError={this.onPlaceObjectError}
  onTrackingQualityInfo={this.onTrackingQualityInfo} />

Source

The source prop on both ModelView and ARView can either be a url to a server (e.g. http://example.com/yourmodel.obj) or a local path (use require). The source object can either consist of a zip prop or a model and a texture prop. Examples:

source={{
  zip: 'https://github.com/BonnierNews/react-native-3d-model-view/blob/master/example/obj/Hamburger.zip?raw=true'
}}

or

source={{
  zip: require('../obj/Hamburger.zip')
}}

or

source={{
  model: 'https://github.com/BonnierNews/react-native-3d-model-view/blob/master/example/obj/Hamburger.obj?raw=true',
  texture: 'https://github.com/BonnierNews/react-native-3d-model-view/blob/master/example/obj/Hamburger.png?raw=true'
}}

or

source={{
  model: require('../obj/Hamburger.obj'),
  texture: require('../obj/Hamburger.png')
}}

The lib will assume that the unzipped folder result will have the same name as the .zip (e.g. Hamburger.zip => Hamburger). This might not always be the case, then you can set the name of the unzipped folder:

source={{
  zip: 'https://github.com/BonnierNews/react-native-3d-model-view/blob/master/example/obj/Archive.zip?raw=true',
  unzippedFolderName: 'Hamburger'
}}

NOTE: File types

WaveFront (.obj) and Collada (.dae) is supported on both Android and iOS. SceneKit (.scn) is supported on iOS. Collada models with animations is autoplayed.

NOTE: Using require

To require .obj, .dae, .scn or .zip files you need to add a rn-cli.config.js to the root of your project with minimum this config:

const { getDefaultConfig } = require("metro-config");

module.exports = (async () => {
  const { resolver: { assetExts } } = await getDefaultConfig();

  return { resolver: { assetExts: assetExts.concat(['obj', 'dae', 'scn', 'zip']) } };
})();

See more in the example project.

NOTE: SceneKit compressed scenes

SceneKit and Collade files needs to be "SceneKit compressed scenes" on iOS. Compress with this shell command

$ /Applications/Xcode.app/Contents/Developer/usr/bin/scntool --convert InFile.dae --format c3d --output OutFile.dae --force-y-up --force-interleaved --look-for-pvrtc-image

Components

ModelView

View for displaying .obj, .dae or .scn (iOS only) on screen with SceneKit or OpenGL.

Props

Prop	Type	Default	Note
source	object	null	Can either consist of a zip prop or a model and a texture prop. All three can either be a url string ("http://...") or you can use require to reference a local path. The .zip archive should contain both the object and the texture. Can also contain unzippedFolderName for setting the unzipped folder name (see more above).
scale	number	1	Scale of the model.
autoPlay	boolean	true	Should animated models play on mount.

Events

Event Name	Returns	Notes
onLoadModelStart	null	Loading model has started.
onLoadModelSuccess	null	Loading model has succeeded.
onLoadModelError	Error	Failed loading model.
onAnimationStart	null	Animated model has started animating.
onAnimationStop	null	Animated model has stopped animating.
onAnimationUpdate	event	Animated model animation update. Get progress from event.nativeEvent.progress

Methods

Use ref={modelView => {this.modelView = modelView}} to be able to call the methods listed below.

Method Name	Returns	Notes
startAnimation	null	Start playing animated model.

Thanks

• The entire Android implementation is made by andresoviedo. I have only ported his Android 3D Model Viewer repo to React Native.
• Most of the ARKit implementation is taken from the Handling 3D Interaction and UI Controls in Augmented Reality project made by Apple. I have only ported this project to React Native.
