MRTK-Unity is a Microsoft driven project that provides a set of components and features to accelerate cross-platform MR app development in Unity. Here are some things MRTK does:
- Provides the basic building blocks for Unity development on HoloLens, Windows Mixed Reality, and OpenVR.
- Enables rapid prototyping via in-editor simulation that allows you to see changes immediately.
- Designed as an extensible framework that provides developers ability to swap out core components.
- Supports a wide range of platforms, including
- Microsoft HoloLens
- Microsoft HoloLens 2
- Windows Mixed Reality headsets
- OpenVR headsets (HTC Vive / Oculus Rift)
