HoloLens research mode streams made available for use in Unity through IL2CPP Windows Runtime support. See my blog post for more information on the sample.

Incorporates:

• HoloLensForCV sample from Microsoft
• depthPvMapper from cyberj0g

Requirements

• Tested with Unity 2018.4 LTS
• Visual Studio 2017
• Minimum RS4, tested with OS Build 17763.678
• HoloLens with research mode enabled

Sensor Stream Sample

1. Open HoloLensForCV sample in VS2017 and install included OpenCV nuget package to HoloLensForCV project
2. Build the HoloLensForCV project (x86, Debug or Release)
3. Copy all output files from HoloLensForCV output path (dlls and HoloLensForCV.winmd) to the Assets->Plugins->x86 folder of the HoloLensForCVUnity project
4. Open HoloLensForCVUnity Unity project and build using IL2CPP, allow unsafe code under Unity Player Settings->Other Settings
5. Navigate to Unity project build folder and modify the Package.appxmanifest file to include:

• Restricted capabilities package:

<Package

    <rescap:Capability Name="perceptionSensorsExperimental" />
    <Capability Name="internetClient" />
    <Capability Name="internetClientServer" />
    <Capability Name="privateNetworkClientServer" />
    <uap2:Capability Name="spatialPerception" />
    <DeviceCapability Name="webcam" />
