Now it's time for some actual code. So far if we'd build the project and open it with Visual Studio Code, it'd be executable on the HoloLens Emulator. However, there's nothing to do. That's about to change. Read more...

In this part we'll import the 3D-Objects that were created using 3DSlicer and then use them as assets in the HoloLens application. This part I'll create three GameOjects and implement simple ways of interaction. Let's get started. Read more...
