Unity

About

• Unity is a cross-platform game engine developed by Unity Technologies.
• It supports multiple platforms such as desktop, mobile, console, virtual and augmented reality platforms.
• The engine can be used to create three-dimensional and two-dimensional games, as well as interactive simulations and other experiences (IA, AR/VR, film, engineering ...).
• The UI allows to easily add and move elements in the game world, while scripts are coded in C#.

Licensing system

• The proof of concepts can be built with the personal, free license.
• If the project is carried further, some license may be required (strongly depends on the company income). Please see here

Getting started with Unity

• The Roll-a-Ball tutorial is a great first look into the editor.
• For AR systems on the Hololens2, Microsoft also offers some tutorials, although a bit disjointed and more complex to understand without knowing the tool.

Unit system

The scales in Unity are unit-less. For the Hololens and mixed reality in general, 1 unit corresponds to 1 meter in real life.
