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:

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)
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

Methods

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

Method Name	Returns	Notes
`startAnimation`	`null`	Start playing animated model.
`stopAnimation`	`null`	Stops playing animated model.
