3 years ago After a lot of test I success to make it work! Just copy these dlls to same folder of exe file:
And, I also install "Microsoft.Windows.MixedReality.DotNetWinRT" package from nuget. Then change some code of SpatialGraphCoordinateSystem.cs so that the tracking can work in editor and standalone build:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Microsoft.Windows.Perception.Spatial;
using Microsoft.MixedReality.Toolkit.Utilities;
namespace QRTracking
{
public class SpatialGraphCoordinateSystem : MonoBehaviour
{
private SpatialCoordinateSystem CoordinateSystem = null;
private System.Guid id;
public System.Guid Id
{
get
{
return id;
}
set
{
id = value;
CoordinateSystem = Microsoft.Windows.Perception.Spatial.Preview.SpatialGraphInteropPreview.CreateCoordinateSystemForNode(id);
if (CoordinateSystem == null)
{
Debug.Log("Id= " + id + " Failed to acquire coordinate system");
}
}
}
void Awake()
{
}
// Use this for initialization
void Start()
{
if (CoordinateSystem == null)
{
CoordinateSystem = Microsoft.Windows.Perception.Spatial.Preview.SpatialGraphInteropPreview.CreateCoordinateSystemForNode(id);
if (CoordinateSystem == null)
{
Debug.Log("Id= " + id + " Failed to acquire coordinate system");
}
}
}
private void UpdateLocation()
{
{
if (CoordinateSystem == null)
{
CoordinateSystem = Microsoft.Windows.Perception.Spatial.Preview.SpatialGraphInteropPreview.CreateCoordinateSystemForNode(id);
if (CoordinateSystem == null)
{
Debug.Log("Id= " + id + " Failed to acquire coordinate system");
}
}
if (CoordinateSystem != null)
{
Quaternion rotation = Quaternion.identity;
Vector3 translation = new Vector3(0.0f, 0.0f, 0.0f);
System.IntPtr rootCoordnateSystemPtr = UnityEngine.XR.WindowsMR.WindowsMREnvironment.OriginSpatialCoordinateSystem;
if (rootCoordnateSystemPtr != System.IntPtr.Zero)
{
var rootSpatialCoordinateSystem = SpatialCoordinateSystem.FromNativePtr(rootCoordnateSystemPtr);
// Get the relative transform from the unity origin
System.Numerics.Matrix4x4? relativePose = CoordinateSystem.TryGetTransformTo(rootSpatialCoordinateSystem);
if (relativePose != null)
{
System.Numerics.Vector3 scale;
System.Numerics.Quaternion rotation1;
System.Numerics.Vector3 translation1;
System.Numerics.Matrix4x4 newMatrix = relativePose.Value;
// Platform coordinates are all right handed and unity uses left handed matrices. so we convert the matrix
// from rhs-rhs to lhs-lhs
// Convert from right to left coordinate system
newMatrix.M13 = -newMatrix.M13;
newMatrix.M23 = -newMatrix.M23;
newMatrix.M43 = -newMatrix.M43;
newMatrix.M31 = -newMatrix.M31;
newMatrix.M32 = -newMatrix.M32;
newMatrix.M34 = -newMatrix.M34;
System.Numerics.Matrix4x4.Decompose(newMatrix, out scale, out rotation1, out translation1);
translation = new Vector3(translation1.X, translation1.Y, translation1.Z);
rotation = new Quaternion(rotation1.X, rotation1.Y, rotation1.Z, rotation1.W);
Pose pose = new Pose(translation, rotation);
// If there is a parent to the camera that means we are using teleport and we should not apply the teleport
// to these objects so apply the inverse
if (CameraCache.Main.transform.parent != null)
{
pose = pose.GetTransformedBy(CameraCache.Main.transform.parent);
}
gameObject.transform.SetPositionAndRotation(pose.position, pose.rotation);
//Debug.Log("Id= " + id + " QRPose = " + pose.position.ToString("F7") + " QRRot = " + pose.rotation.ToString("F7"));
}
else
{
// Debug.Log("Id= " + id + " Unable to locate qrcode" );
}
}
}
else
{
gameObject.SetActive(false);
}
}
}
// Update is called once per frame
void Update()
{
UpdateLocation();
}
}
}
Hello, I use Unity 2020.3.14f1 and remoting to Hololens 2 in editor, after fix some missing reference issue, everything is good, I can detect and track QR codes. After I build a windows standalone, I get something like "... cannot find vcruntime140_app.dll ...", then I copy the dlls from Plugins folder to the the same folder of exe and a new error shows, a "COMExcpetion" error:
What can I do to solve it?
