The HoloLens development environment breaks down into two primary tools, Unity and Visual Studio. Unity is the 3D environment that we will do most of our work in; this includes adding holograms, creating user interface elements, adding sound and particle systems, and other things that bring a 3D program to life.

Visual Studio on the other hand is the glue that makes everything work. Here, we write scripts or machine code to make our 3D creations come to life and add a level of control and immersion that Unity cannot produce on its own.
