A-npanRemote

REMOTE to UnityEditor parameter streaming kit.

example(ARKitFaceTracking) usage

1. sample codes are below.

var ip = "Unity Editor IP(x.x.x.x)";

// init facetracking.
var fTrack = new ARFaceTracking();
fTrack.StartTracking(
    () =>
    {
        // on start face tracking.
    },
    (faceMat4x4, faceBlendShapes, cameraRot) =>
    {
        // on update face tracking.
    }
);

// add A_npanRemote setup method.
// these block will be disappeared when "REMOTE" scriptingDefineSymbol is removed. 
A_npanRemote.Setup<Matrix4x4, Dictionary<string, float>, Quaternion, FaceTrackingPayload>(
    validInput,
    ref fTrack.OnUpdate
);

2. run iOS test app with A-npanRemote and input Unity Editor IP.
3. run same apps on UnityEditor too.

so now you can receive Face tracking data on your Unity Editor from the iOS device.

installation

use unitypackage.

application for your parameter streaming

A-npanRemote is easy to extend for other remote system. like VR.

class VRTracking 
{
    public void StartTracking(
        GameObject[] cameraLeftAndRight, 
        Action<
            VRTransform, // head position and rotation
            HandInput, // left hand position and rotation and triggers
            HandInput // right hand position and rotation and triggers
        > update)
    {
        // start tracking.
        StartCoroutine(OnUpdate(cameraLeftAndRight, update));
    }
    ...
}

// usage
var vrTrack = new VRTracking();
vrTrack.StartTracking(
    objects,
    (head, leftHand, rightHand) =>
    {
        // on update vr tracking.
    }
);

step is below.

1. define IRemotePayload1, 2 or 3 payload type for streaming.

IRemotePayload types are container of parameters for streming.

IRemotePayload1 : convert 1 parameter into 1 remotePayload.
IRemotePayload2 : convert 2 parameters into 1 remotePayload.
IRemotePayload3 : convert 3 parameters into 1 remotePayload.

in this case, 3 parameters required and convert it into IRemotePayload3.

public class VRTrackingPayload : IRemotePayload3
{
    [SerializeField] public VRTransform headCamera;// 0
    [SerializeField] public HandInput leftHand;// 1
    [SerializeField] public HandInput rightHand;// 2

    public object Param0()
    {
        return headCamera;// return 0 index data.
    }

    public object Param1()
    {
        return leftHand;// return 1 index data.
    }

    public object Param2()
    {
        return rightHand;// return 2 index data.
    }
}

2. expose the method for receiving original 3parameters. e,g,

class VRTracking 
{
    // expose OnTracking method.
    public Action<VRTransform, HandInput, HandInput> OnTracking;

    public void StartTracking(
        GameObject[] cameraLeftAndRight, 
        Action<
            VRTransform, // head position and rotation
            HandInput, // left hand position and rotation and triggers
            HandInput // right hand position and rotation and triggers
        > update)
    {
        // set OnTracking method.
        this.OnTracking = update;

        // start tracking.
        StartCoroutine(OnUpdate(cameraLeftAndRight, this.OnTracking));
    }
    ...
}

3. write setup code of A-npanRemote.

var ip = "Unity Editor IP(x.x.x.x)";

var vrTrack = new VRTracking();
vrTrack.StartTracking(
    objects,
    (head, leftHand, rightHand) =>
    {
        // on update vr tracking.
    }
);

// setup A-npanRemote.
A_npanRemote.Setup<VRTransform, HandInput, HandInput, VRTrackingPayload>(
    ip,
    ref vrTrack.OnUpdate// set reference of exposed Update method.
);

4. define "REMOTE" scriptingDefineSymbol for remote tracking

A-npanRemote runs when "REMOTE" symbol is set.

it's done! vr tracking data from OculusQuest will reaches your UnityEditor.
