Build Instructions

1. Go to File > Build Settings
2. Click Build
3. The Unity editor will open a dialog box asking where you want the project to built be built. Select a folder. I use a folder named 'VS' in the Unity project directory (HoloArt/VS).
4. Open the solution file (HoloArt/VS/HoloArt.sln) in Visual Studio 2019 (Community Edition).
5. Set the Solutions Platforms to x86.
6. Optional: Double click on Package.appxmanifest in the Solution Explorer, switch to the Capabilities tab, and check that the following are enabled:
   • Gaze Input
   • Internet (Client)
   • Microphone
   • Spatial Perception
   • Webcam
7. Build the solution: Build > Build Solution.
8. Deploy to Remote Machine

Note: To set the deployment target to HoloLens:

• Ensure that the HoloLens is switched on.
• Right click the HoloArt project in the Solution Explorer.
• Select Properties.
• Go to Debugging.
• Select Machine and then click Locate from the dropdown menu.
• Select the HoloLens device

To Do List

• Tidy up source code.
• Document source code.
• TextureScale class is currently disabled. This is called by DisplayPanel.DownloadThumbnailImage(). TextureScale will not compile when the Scripting Backend (PlayerSettings > Other Settings) is set to .NET. Could try switching to IL2CPP or find some other way to rescale the thumbnail image.
• Create a close box for the holographic display panel. Look at examples from HoloToolkit. It should be possible to close a display panel by selecting the close box.
• Display panels are closed using a "Close" voice command, which invokes AppManager.CloseWindows(). Consider destroying the display panel game object rather than setting the game object to false.
• AppManager.CloseWindows() uses GameObject.FindGameObjectsWithTag(), which is resource intensive. Implement alternative solution to manage open display panels.
• ImageCapture.GetImage() attempts to calculate a target position for the display position (this.CalculateDisplayPanelPosition()). Exceptions are thrown when this code is run, so the routine is disabled. Investigate the source of the exceptions and attempt to resolve.
