react-native-arkit

React Native binding for iOS ARKit.

Made with React Native Arkit:

Homestory: An AI powered interior design assistant (App store)

Tutorial: How to make an ARKit app in 5 minutes using React Native

Sample Project: https://github.com/HippoAR/ReactNativeARKit

Note: ARKit is only supported by devices with A9 or later processors (iPhone 6s/7/SE/8/X, iPad 2017/Pro) on iOS 11. You also need Xcode 9 to build the project.

There is a Slack group that anyone can join for help / support / general questions.

Getting started

$ yarn add react-native-arkit

make sure to use the latest version of yarn (>=1.x.x)

(npm does not work properly at the moment. See #103)

Mostly automatic installation

⚠️ Currently automatic installation does not work as PocketSVG is missing. Follow the manual installation.

$ react-native link react-native-arkit

Manual installation

iOS

In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
Go to node_modules ➜ add react-native-arkit/ios/RCTARKit.xcodeproj and react-native-arkit/ios/PocketSVG/PocketSVG.xcodeproj
In XCode, in the project navigator, select your project. Add libRCTARKit.a and PocketSVG.framework to your project's Build Phases ➜ Link Binary With Libraries
In Tab General ➜ Embedded Binaries ➜ + ➜ Add PocketSVG.framework ios
Run your project (Cmd+R)<

iOS Project configuration

These steps are mandatory regardless of doing a manual or automatic installation:

Give permissions for camera usage. In Info.plist add the following:

<key>NSCameraUsageDescription</key>
<string>Your message to user when the camera is accessed for the first time</string>

ARKit only runs on arm64-ready devices so the default build architecture should be set to arm64: go to Build settings ➜ Build Active Architecture Only and change the value to Yes.

Usage

A simple sample React Native ARKit App

// index.ios.js

import React, { Component } from 'react';
import { AppRegistry, View } from 'react-native';
import { ARKit } from 'react-native-arkit';

export default class ReactNativeARKit extends Component {
  render() {
    return (
      <View style={{ flex: 1 }}>
        <ARKit
          style={{ flex: 1 }}
          debug
          // enable plane detection (defaults to Horizontal)
          planeDetection={ARKit.ARPlaneDetection.Horizontal}

          // enable light estimation (defaults to true)
          lightEstimationEnabled
          // get the current lightEstimation (if enabled)
          // it fires rapidly, so better poll it from outside with
          // ARKit.getCurrentLightEstimation()
          onLightEstimation={e => console.log(e.nativeEvent)}

          // event listener for (horizontal) plane detection
          onPlaneDetected={anchor => console.log(anchor)}

          // event listener for plane update
          onPlaneUpdated={anchor => console.log(anchor)}

          // arkit sometimes removes detected planes
          onPlaneRemoved={anchor => console.log(anchor)}

          // event listeners for all anchors, see [Planes and Anchors](#planes-and-anchors)
          onAnchorDetected={anchor => console.log(anchor)}
          onAnchorUpdated={anchor => console.log(anchor)}
          onAnchorRemoved={anchor => console.log(anchor)}

          // you can detect images and will get an anchor for these images
          detectionImages={[{ resourceGroupName: 'DetectionImages' }]}


          onARKitError={console.log} // if arkit could not be initialized (e.g. missing permissions), you will get notified here

`<ARKit />`-Component

Props

Prop	Type	Note
`debug`	`Boolean`	Debug mode will show the 3D axis and feature points detected.
`planeDetection`	`ARKit.ARPlaneDetection.{ Horizontal \| Vertical \| HorizontalVertical \| None }`	ARKit plane detection. Defaults to `Horizontal`. `Vertical` is available with IOS 11.3
`lightEstimationEnabled`	`Boolean`	ARKit light estimation (defaults to false).
`worldAlignment`	`ARKit.ARWorldAlignment.{ Gravity \| GravityAndHeading \| Camera }`	ARWorldAlignmentGravity The coordinate system's y-axis is parallel to gravity, and its origin is the initial position of the device. ARWorldAlignmentGravityAndHeading The coordinate system's y-axis is parallel to gravity, its x- and z-axes are oriented to compass heading, and its origin is the initial position of the device. ARWorldAlignmentCamera The scene coordinate system is locked to match the orientation of the camera. Defaults to `ARKit.ARWorldAlignment.Gravity`. See
`origin`	`{position, transition}`	Usually `{0,0,0}` is where you launched the app. If you want to have a different origin, you can set it here. E.g. if you set `origin={{position: {0,-1, 0}, transition: {duration: 1}}}` the new origin will be one meter below. If you have any objects already placed, they will get moved down using the given transition. All hit-test functions or similar will report coordinates relative to that new origin as `position`. You can get the original coordinates with `positionAbsolute` in these functions
`detectionImages`	`Array<DetectionImage>`	An Array of `DetectionImage` (see below), only available on IOS 11.3

`DetectionImage`

An DetectionImage is an image or image resource group that should be detected by ARKit.

See https://developer.apple.com/documentation/arkit/arreferenceimage?language=objc how to add these images.

You will then receive theses images in onAnchorDetected/onAnchorUpdated. See also Planes and Anchors for more details.

DetectionImage has these properties

Prop	Type	Notes
`resourceGroupName`	`String`	The name of the resource group

We probably will add the option to load images from other sources as well (PRs encouraged).

Events

Event Name	Returns	Notes
`onARKitError`	`ARKiterror`	will report whether an error occured while initializing ARKit. A common error is when the user has not allowed camera access. Another error is, if you use `worldAlignment=GravityAndHeading` and location service is turned off
`onLightEstimation`	`{ ambientColorTemperature, ambientIntensity }`	Light estimation on every frame. Called rapidly, better use polling. See `ARKit.getCurrentLightEstimation()`
`onFeaturesDetected`	`{ featurePoints}`	Detected Features on every frame (currently also not throttled). Usefull to display custom dots for detected features. You can also poll this information with `ARKit.getCurrentDetectedFeaturePoints()`
`onAnchorDetected`	`Anchor`	When an anchor (plane or image) is first detected.
`onAnchorUpdated`	`Anchor`	When an anchor is updated
`onAnchorRemoved`	`Anchor`	When an anchor is removed
`onPlaneDetected`	`Anchor`	When a plane anchor is first detected.
`onPlaneUpdated`	`Anchor`	When a detected plane is updated
`onPlaneRemoved`	`Anchor`	When a detected plane is removed

See Planes and Anchors for Details about anchors

Planes and Anchors

ARKit can detect different anchors in the real world:

plane horizontal and vertical planes
image, image-anchors See DetectionImage
face with iphone X or similar (not implemented yet)

You then will receive anchor objects in the onAnchorDetected, onAnchorUpdated, onAnchorRemoved callbacks on your <ARKit />-component.

You can use onPlaneDetected, onPlaneUpdated, onPlaneRemoved to only receive plane-anchors (may be deprecated later).

The Anchor object has the following properties:

Property	Type	Description
`id`	`String`	a unique id identifying the anchor
`type`	`String`	The type of the anchor (plane, image)
`position`	`{ x, y, z }`	the position of the anchor (relative to the origin)
`positionAbsolute`	`{ x, y, z }`	the absolute position of the anchor
`eulerAngles`	`{ x, y, z }`	the rotation of the plane

If its a plane-anchor, it will have these additional properties:

Property	Description
`alignment`	`ARKit.ARPlaneAnchorAlignment.Horizontal` or `ARKit.ARPlaneAnchorAlignment.Vertical` so you can check whether it was a horizontal or vertical plane
`extent`	see https://developer.apple.com/documentation/arkit/arplaneanchor?language=objc
`center`	see https://developer.apple.com/documentation/arkit/arplaneanchor?language=objc

image-Anchor:

Property	type	Description
`image`	`{name}`	an object with the name of the image.

Static methods

Static Methods can directly be used on the ARKit-export:

import { ARKit } from 'react-native-arkit'

//...
const result = await ARKit.hitTestSceneObjects(point);

All methods return a promise with the result.

Method Name	Arguments	Notes
`snapshot`
`snapshotCamera`		Take a screenshot without 3d models (will save to Photo Library)
`getCameraPosition`		Get the current position of the `ARCamera`
`getCamera`		Get all properties of the `ARCamera`
`getCurrentLightEstimation`		Get current light estimation `{ ambientColorTemperature, ambientIntensity}`
`getCurrentDetectedFeaturePoints`		Get current detected feature points (in last current frame) (array)
`focusScene`		Sets the scene's position/rotation to where it was when first rendered (but now relative to your device's current position/rotation)
`hitTestPlanes`	point, type	check if a plane has ben hit by point (`{x,y}`) with detection type (any of `ARKit.ARHitTestResultType`). See https://developer.apple.com/documentation/arkit/arhittestresulttype?language=objc for further information
`hitTestSceneObjects`	point	check if a scene object has ben hit by point (`{x,y}`)
`isInitialized`	boolean	check whether arkit has been initialized (e.g. by mounting). See #152 for details
`isMounted`	boolean	check whether arkit has been mounted. See #152 for details

3D-Components

This project allows you to work with 3d elements like with usual react-components. We provide some primitive shapes like cubes, spheres, etc. as well as a component to load model-files.

You can also nest components to create new Components. Child-elements will be relative to the parent:

const BigExclamationMark = ({ position, eulerAngles, color = '#ff0000' }) => (
  <ARKit.Group opacity={0.5} position={position} eulerAngles={eulerAngles}>
    <ARKit.Sphere
      position={{ x: 0, y: 0, z: 0 }}
      shape={{ radius: 0.06 }}
      material={{ diffuse: color }}
    />
    <ARKit.Cone
      position={{ x: 0, y: 0.4, z: 0 }}
      shape={{ topR: 0.1, bottomR: 0.05, height: 0.5 }}
      material={{ diffuse: color }}
    />
  </ARKit.Group>
)

// somewhere else

<BigExclamationMark
  eulerAngles={{ x: 0.2 }}
  position={{ x: 0.2, y: 0.3, z: -0.2 }}
  color="#00ff00"
/>

General props

Most 3d object have these common properties

Prop	Type	Description
`position`	`{ x, y, z }`	The object's position (y is up)
`scale`	Number	The scale of the object. Defaults to 1
`eulerAngles`	`{ x, y, z }`	The rotation in eulerAngles
`id`	String	a unique identifier. Only provide one, if you need to find the node later in hit-testing.
`shape`	depends on object	the shape of the object (will probably renamed to geometry in future versions)
`material`	`{ diffuse, metalness, roughness, lightingModel, shaders }`	the material of the object
`transition`	`{duration: 1}`	Some property changes can be animated like in css transitions. Currently you can specify the duration (in seconds).

Advanced properties:

Prop	Type	Description
`rotation`	TODO	see scenkit documentation
`orientation`	TODO	see scenkit documentation
`renderingOrder`	Number	Order in which object is rendered. Usefull to place elements "behind" others, although they are nearer.

`castsShadow`	`boolean`	whether this object casts shadows
`constraint`	`ARKit.Constraint.{ BillboardAxisAll \| BillboardAxisX \| BillboardAxisY \| BillboardAxisZ \| None }`	Constrains the node to always point to the camera

New experimental feature:

You can switch properties on mount or onmount by specifying propsOnMount and propsOnUnmount. E.g. you can scale an object on unmount:

<ARKit.Sphere
  position={{x:0,y:0,z:0}}
  scale={1}
  transition={{duration: 1}}
  propsOnUnmount={{
    scale: 0
  }}
/>

`shape`	`{ width, height, length, chamfer }`

And any common object property (position, material, etc.)

`<ARKit.Sphere />`

Prop	Type
`shape`	`{ radius }`

`<ARKit.Cylinder />`

Notice: planes are veritcally aligned. If you want a horizontal plane, rotate it around the x-axis.

Example:

This is a horizontal plane that only receives shadows, but is invisible otherwise:

<ARKit.Plane
    eulerAngles={{ x: Math.PI / 2 }}
    position={floorPlane.position}
    renderingOrder={9999}
    material={{
      color: '#ffffff',

SceneKit only supports .scn and .dae formats.

Prop	Type
`model`	`{ file, node, scale, alpha }`

Objects currently don't take material property.

`<ARKit.Shape />`

Creates a extruded shape by an svg path. See #89 for details

Prop	Type
`shape`	`{ pathSvg, extrusion, pathFlatness, chamferRadius, chamferProfilePathSvg, chamferProfilePathFlatness }`

`<ARKit.Light />`

Place lights on the scene!

You might set autoenablesDefaultLighting={false} on The <ARKit /> component to disable default lighting. You can use lightEstimationEnabled and ARKit.getCurrentLightEstimation() to find values for intensity and temperature. This produces much nicer results then autoenablesDefaultLighting.

Prop	Type	Description
`position`	`{ x, y, z }`
`eulerAngles`	`{ x, y, z }`
`type`	any of `ARKit.LightType`	see here for details

`temperature`	`Number`	The color temperature of the light
`intensity`	`Number`	The light intensity
`lightCategoryBitMask`	`Number`/`bitmask`	control which objects are lit by this light
`castsShadow`	`boolean`	whether to cast shadows on object
`shadowMode`	`ARKit.ShadowMode.*	Define the shadowmode. Set to `ARKit.ShadowMode.Deferred` to cast shadows on invisible objects (like an invisible floor plane)

Most properties described here are also supported: https://developer.apple.com/documentation/scenekit/scnlight

This feature is new. If you experience any problem, please report an issue!

HOCs (higher order components)

withProjectedPosition()

this hoc allows you to create 3D components where the position is always relative to the same point on the screen/camera, but sticks to a plane or object.

Think about a 3D cursor that can be moved across your table or a 3D cursor on a wall.

You can use the hoc like this:

const Cursor3D = withProjectedPosition()(({positionProjected, projectionResult}) => {
  if(!projectionResult) {
    // nothing has been hit, don't render it
    return null;
  }
  return (
    <ARKit.Sphere
      position={positionProjected}
      transition={{duration: 0.1}}
      shape={{
        radius: 0.1
        }}
    />
  )
})

It's recommended that you specify a transition duration (0.1s works nice), as the position gets updated rapidly, but slightly throttled.

Now you can use your 3D cursor like this:

Attach to a given detected horizontal plane

Given you have detected a plane with onPlaneDetected, you can make the cursor stick to that plane:

<Cursor3D projectPosition={{
  x: windowWidth / 2,
  y: windowHeight / 2,
  plane: "my-planeId"
  }}
/>

If you don't have the id, but want to place the cursor on a certain plane (e.g. the first or last one), pass a function for plane. This function will get all hit-results and you can return the one you need:

<Cursor3D projectPosition={{
  x: windowWidth / 2,
  y: windowHeight / 2,
  plane: (results) => results.length > 0 ? results[0] : null
  }}
/>

You can also add a property onProjectedPosition to your cursor which will be called with the hit result on every frame

It uses https://developer.apple.com/documentation/arkit/arframe/2875718-hittest with some default options. Please file an issue or send a PR if you need more control over the options here!

Attach to a given 3D object

You can attach the cursor on a 3D object, e.g. a non-horizontal-plane or similar:

Given there is some 3D object on your scene with id="my-nodeId"

<Cursor3D projectPosition={{
  x: windowWidth / 2,
  y: windowHeight / 2,
  node: "my-nodeId"
  }}

Like with planes, you can select the node with a function.

E.gl you have several "walls" with ids "wall_1", "wall_2", etc.

<Cursor3D projectPosition={{
  x: windowWidth / 2,
  y: windowHeight / 2,
  node: results => results.find(r => r.id.startsWith('wall_')),
  }}
/>

It uses https://developer.apple.com/documentation/scenekit/scnscenerenderer/1522929-hittest with some default options. Please file an issue or send a PR if you need more control over the options here!

FAQ:

Which permissions does this use?

camera access (see section iOS Project configuration above). The user is asked for permission, as soon as you mount an <ARKit /> component or use any of its API. If user denies access, you will get an error in onARKitError
location service: only needed if you use ARKit.ARWorldAlignment.GravityAndHeading.

Is there an Android / ARCore version?

Not yet, but there has been a proof-of-concept: #14. We are looking for contributors to help backporting this proof-of-conept to react-native-arkit.

I have another question...
