Note

The project used in this article is on the ForHandDetectionAndTrackingArticle branch.

The master branch is currently used for development and does not guarantee stability.

Description

This demo project shows how to enable the CoreML to work with AR Foundation in Unity.

It is based on the repo implemented on the native iOS platform by Gil Nakache.

The ARFoundation Plugin’s version is 1.5.0-preview.5, you can find it inside the ARPackages folder.

For hand detection, the plugin uses the HandModel machine learning model. This model is from the same repo mentioned above inside the CoreML folder.

Version

Unity Version: 2018.3.13f1

Xcode Version: 10.2.1

iPhone 7: 12.3.1

Implemention

Import ARFoundation Plugin

For convenience, I use the local package import. This is very simple, just modify the manifest.json file in the package folder and add the local package in the project manifest.

    "com.unity.xr.arfoundation": "file:../ARPackages/com.unity.xr.arfoundation",
    "com.unity.xr.arkit": "file:../ARPackages/com.unity.xr.arkit

Create a Swift plugin for Unity

In order for C# to communicate with Swift, you need to create an object-c file as a bridge.

There is a sample. This proj demonstrates how to create a Swift plugin for Unity and print “Hello, I’m Swift” in Unity.

In the Unity-ARFoundation-HandDetection Proj, the structure of the plugins folder is as follows:

<Plugins>
  └── iOS
      ├── HandDetector
      │   ├── Native
      │   │  ├──HandDetector.swift
      │   │  └──HandDetectorBridge.mm
      │   └── Managed
      │      └──HandDetector.cs
      └── Unity
