Running the emulator requires special permission:

Notes on installing Visual Studio components to support building the "player" application referenced in the VTK - OpenXR Holographic Remoting documentation¹.

Step by step

Starts the emulator

Open the solution associate with the player application. After it has been built (see below), it reports the following in the Visual Studio output tab.

ConfigurationParser/Constructor/EnumerateEmulators: START
    NumberOfDevicesFound = 1
    ConfigurationParser/Constructor/EnumerateEmulators/Emulator
	    Id = 32b69331-0d59-2dec-951b-9b4e72ae9a2a
	    Name = HoloLens 2 Emulator 10.0.20348.1535
	    Type = Emulator
	    Version = 10.0.20348.1535
	    UwpVersion = 10.0.20348.1535
ConfigurationParser/Constructor/EnumerateEmulators: END (Success, 0:00:00.146)
ConfigurationParser/Constructor: END (Success, 0:00:00.218)
IsEmulatorSupported: START
    Is64BitOperatingSystem = True
DetectSlat: START
    isHyperVRunning = True
DetectSlat: END (Success, 0:00:00.105)
    SlatState = SlatAndHWVEnabled
    IsEmulatorSupported = True
IsEmulatorSupported: END (Success, 0:00:00.109)

After attempting to start debugging session to run the player app on the emulator, we only see the option Download New emulators

Building the player app

References

Prerequisites

Update Visual Studio 2022 installation (Tools -> Get Tools and Features):

MSVC v143 - VS 2022 C++ ARM64 build tools (Latest)
MSVC v143 - VS 2022 C++ ARM64 Spectre-mitigated libs (Latest)
C++ Universal Windows Platform support for v143 build tools (ARM64)

To address the error message "Sorry, something went wrong"`, see these instructions.

Building

On Windows, build the "player application"

git clone https://github.com/microsoft/MixedReality-HolographicRemoting-Samples

Open player/sample/SamplePlayer.sln with right-click and select Open With -> Visual Studio 2022

On first use, right-click the solution and select Restore NuGet Packages

Select Release

…ctivate Update vtkSlicerMixedRealityLogic: * Add SetMixedRealityConnected/GetMixedRealityConnected * Add SetMixedRealityActive/GetMixedRealityActive * SetDefaultReferenceView

Fixes: ``` Exception thrown: read access violation. this was nullptr. Call stack: vtkRendering-9.1.dll!vtkRenderer::SetActiveCamera(vtkCamera * cam) Line 770 C++ ```

When using remoting, the OpenXR loader must be built dynamically to allow the remoting package to override this loader at runtime. (see RemotingXR.json) Fixes: ``` ERROR [GENERAL | xrGetInstanceProcAddr | OpenXR-Loader]: No active xrInstance handle. ```

Fixes: Unable to open openXR action file : [...]/externals/vtkRenderingOpenXRvtk_openxr_actions.json

This requires VTK MR-10449 (see [1]) backported to Slicer/VTK through the Slicer PR-7190 (see [2]). [1] https://gitlab.kitware.com/vtk/vtk/-/merge_requests/10449 [2] Slicer/Slicer#7190

Adapted from KitwareMedical/SlicerVirtualReality@a4d465b73 Remove the "externals" sub-directory that was specific to branch Slicer/[email protected] integrating commit Slicer/VTK@0ba7af630 ([Backport MR-8123] vtk_module_build: Ensure external modules build directory are not overwritten) Since the approach originally proposed in VTK MR-8123 was superseded by MR-9097 there is no need to specify the "externals" sub-directory.

Note that the vtkMixedRealityViewInteractorStyle still derives from vtkOpenXRInteractorStyle whereas the VirtualReality counterpart derives from vtkMRMLViewInteractorStyle.

The extension can now be built on Windows (and even packaged & installed) without requiring the developer to copy files and libraries.

Next step we will need to refactor SlicerVirtualReality extension so that relevant functionalities can be reused while minimizing duplication:

Refactoring to support OpenVR and OpenXR, and streamline reuse in SlicerMixedReality SlicerVirtualReality#121

We will also have to improve the OpenXR integration so that we can retrieve the position of each controllers & trackers:
