What is the Mixed Reality Toolkit
MRTK is a Microsoft driven open source project.
MRTK-Unity provides a set of foundational components and features to accelerate MR app development in Unity. The latest Release of MRTK (V2) supports HoloLens/HoloLens 2, Windows Mixed Reality, and OpenVR platforms.
- Provides the basic building blocks for Unity development on HoloLens, Windows Mixed Reality, and OpenVR.
- Showcases UX best practices with UI controls that match Windows Mixed Reality and HoloLens Shell.
- Enables rapid prototyping via in-editor simulation that allows you to see changes immediately.
- Extensible framework provides developers ability to swap out core components and extend.
- Supports a wide range of platforms, including
- Microsoft HoloLens
- Microsoft HoloLens 2
- Windows Mixed Reality headsets
- OpenVR headsets (HTC Vive / Oculus Rift)
|Branch||CI Status||Docs Status|
|Windows SDK 18362+||Unity 2018.4.x||Visual Studio 2017||Simulator (optional)|
|To build apps with MRTK v2, you need the Windows 10 May 2019 Update SDK.
To run apps for immersive headsets, you need the Windows 10 Fall Creators Update.
|The Unity 3D engine provides support for building mixed reality projects in Windows 10||Visual Studio is used for code editing, deploying and building UWP app packages||The Emulators allow you test your app without the device in a simulated environment|
Getting Started with MRTK
MRTK Getting Started Guide
UI and Interaction Building blocks
|Button||Bounding Box||Manipulation Handler|
|A button control which supports various input methods including HoloLens 2's articulated hand||Standard UI for manipulating objects in 3D space||Script for manipulating objects with one or two hands|
|2D style plane which supports scrolling with articulated hand input||Example script of using the system keyboard in Unity||A script for making objects interactable with visual states and theme support|
|Various object positioning behaviors such as tag-along, body-lock, constant view size and surface magnetism||Script for lay out an array of objects in a three-dimensional shape||Annotation UI with flexible anchor/pivot system which can be used for labeling motion controllers and object.|
|App Bar||Pointers||Fingertip Visualization|
|UI for Bounding Box's manual activation||Learn about various types of pointers||Visual affordance on the fingertip which improves the confidence for the direct interaction|
|Slider||MRTK Standard Shader||Hand Joint Chaser|
|Slider UI for adjusting values supporting direct hand tracking interaction||MRTK's Standard shader supports various Fluent design elements with performance||Demonstrates how to use Solver to attach objects to the hand joints|
|Eye Tracking: Target Selection||Eye Tracking: Navigation||Eye Tracking: Heat Map|
|Combine eyes, voice and hand input to quickly and effortlessly select holograms across your scene||Learn how to auto scroll text or fluently zoom into focused content based on what you are looking at||Examples for logging, loading and visualizing what users have been looking at in your app|
