Mixed Reality Toolkit-Unity<\/a>\u00a0is an open-source project to share foundational components, building blocks for common interactions and UI controls for building Mixed Reality experiences in Unity.<\/p>\n\n\n\n

From Mixed Reality Toolkit, I picked up some of the most frequently used building blocks and interaction patterns. For each building blocks, I\u2019ll show where you can find the example scene in the repository, and how you can use it in your projects.<\/p>\n\n\n\n

IMPORTANT: This article is about MRTK v1(also known as HoloToolkit).
* Branch name is\u00a0<\/strong>htk_release<\/strong><\/a>
* Release package is\u00a0<\/strong>HoloToolkit<\/strong><\/a>\u00a0<\/strong>2017.4.3.0<\/strong><\/a><\/p>\n\n\n\n

New MRTK v2.0.0 is now available with HoloLens 2\u2019s articulated Hand Tracking and Eye Tracking input support. (9\/1\/2019)
* Branch name is\u00a0<\/strong>mrtk_release<\/strong><\/a>
* Available on the\u00a0<\/strong>Release Page<\/strong><\/a><\/p>\n\n\n\n

MRTK v2 is NOT compatible with MRTK v1(HoloToolkit)<\/em><\/strong>. However, most of the building blocks have been ported over MRTK v2.\u00a0<\/em>Please see\u00a0<\/em><\/strong>the new documentation portal for more details about new building blocks in MRTK v2<\/em><\/strong><\/a>.<\/em><\/strong><\/p>\n<\/blockquote>\n\n\n

Whether you are creating apps for HoloLens or immersive headset, you need to set up your scene with proper input module, camera, cursor or motion controllers to interact with your content. And Mixed Reality Toolkit makes it easy.<\/p>\n\n\n\n

Example Scenes<\/h2>\n\n\n\n

When you first start creating apps for mixed reality, these two example scenes are the perfect place to start with.<\/p>\n\n\n\n

InputManagerTest and MotionControllerTest scene<\/figcaption><\/figure>\n\n\n\n

Through these scenes, you can learn how to use MRTK\u2019s InputManager and access data handle events from the motion controller buttons.<\/p>\n\n\n\n

How to use: automatic scene setup<\/h2>\n\n\n\n

When you import\u00a0MRTK release Unity packages<\/a>\u00a0or clone the project from the GitHub repository, you are going to find a new menu \u2018Mixed Reality Toolkit<\/strong>\u2019 in Unity.<\/p>\n\n\n\n

\"\"\/<\/figure>\n\n\n\n

Under \u2018Configure\u2019 menu, you will see the menu \u2018Apply Mixed Reality Scene Settings\u2019.<\/p>\n\n\n\n

\"\"\/<\/figure>\n\n\n\n

When you click it, it removes the default camera and adds foundational components \u2014\u00a0InputManager<\/strong><\/a>,\u00a0MixedRealityCameraParent,<\/strong><\/a>\u00a0<\/strong>and\u00a0DefaultCursor<\/strong><\/a>.<\/p>\n\n\n\n

You can also manually add these from the project panel. You can find these components as prefabs. When you search\u00a0MixedRealityCamera<\/strong>, you will be able to see two different camera prefabs.<\/p>\n\n\n\n

\"\"\/<\/figure>\n\n\n\n

The difference is,\u00a0MixedRealityCamera\u00a0<\/strong>is the camera only prefab whereas,\u00a0MixedRealityCameraParent\u00a0<\/strong>includes additional components for the immersive headsets such as\u00a0Teleportation<\/strong>,\u00a0Motion Controller<\/strong><\/a>\u00a0and,\u00a0Boundary<\/strong>.<\/p>\n\n\n\n

MixedRealtyCamera\u00a0<\/strong>supports both HoloLens and immersive headset. It detects the device type and optimizes the properties such as clear flags and Skybox.<\/p>\n\n\n\n

Below you can find some of the useful properties you can customize such as custom Cursor, Motion Controller models, and Floor.<\/p>\n\n\n\n
