Exploring MRTK3 sample scenes

Unlike MRTK2, MRTK3 isn’t distributed as a Unity project. Instead, MRTK3 consists of a loosely coupled collection of individual UPM packages distributed through our official GitHub repository.

As a result, we no longer ship our sample scenes inside the MRTK library/package itself. Instead, we maintain the UnityProjects folder at the top level of the GitHub repository, which contains any Unity projects we want to ship. Currently, this folder includes the MRTKDevTemplate project, which contains all of our example scenes and is configured to align with our recommended best settings.

We also recommend using the MRTKDevTemplate project for local development when submitting fixes or changes. All of the packages are specified as local on-disk dependencies, making editing and submitting changes easy. Clone the repo and open the MRTKDevTemplate Unity project.

Within MRTKDevTemplate, you can find all of our sample scenes. Most of the sample scenes are in UnityProjects/MRTKDevTemplate/Assets/Scenes, while some experimental or early-preview sample scenes are located in UnityProjects/MRTKDevTemplate/Assets/Data Binding Example.

Included sample scenes

A non-exhaustive list can be found below.

HandInteractionExamples

This sample scene offers a wide variety of interaction examples. Despite the name, this scene is a good example of cross-platform input, including hand tracking, controller input, and mouse input. Examples of several different UI controls and interactables are present, including the volumetric UI systems.

BoundsControlExamples

Various configurations of BoundsControl, showing both flattened and 3D bounds.

CanvasExample

Shows a collection of UX components built with UnityUI. These UX components are built with a combination of XRI interactables and traditional UGUI event handlers. This combination enables flexibility and responsive design across a wide variety of input methods and contexts.

CanvasUITearsheet

This scene showcases all available UI building blocks and their permutations in MRTK. All controls are based on the new Mixed Reality Design Language.

DialogExample

This scene demonstrates use of the Dialog control.

EyeGazeExample

Example of using the Gaze Interactor to highlight objects within a scene.

HandMenuExamples

Demonstrates using a menu appearing beside the hand.

InteractableButtonExamples

An example of different styles of interactable buttons.

NearMenuExamples

Near interaction menu examples.

NonCanvasObjectBarExample

Demonstrates the Object Bar component, which enables horizontal or vertical arrangement of arbitrary 3D objects.

NonCanvasUIBackplateExample

The scene demonstrates UIBackplate.prefab, which you can use to construct various types of UI panels and menus.

SampleEmptyMRTKScene

The sample empty MRTK scene only contains the core MRTK prefab (MRTK XR Rig) and the input simulator prefab (MRTKInputSimulator). It’s intended to give developers an empty scene with only the MRTK essentials necessary to get started.

SlateDrawingExample

A demonstration of using MRTK3 to create a basic drawing application.

SpatialMappingExample

The spatial mapping example scene demonstrates using ARMeshManager (MRTK XR Rig > ARSpatialMeshManager) in MRTK3 to visualize the spatial mesh.

TabViewExample

Shows a collection of toggles that control the visibility of associated game objects.

ToggleCollectionExample

Demonstrates the ToggleCollection script, which allows multiple toggle interactables to be grouped. Only one toggle can be toggled at any given time.
