Azure Kinect Examples for Unity, v1.6 (also available at the Unity Asset store) is a set of Azure Kinect (aka ‘Kinect for Azure’, K4A) examples that use several major scripts, grouped in one folder. The package currently contains over twenty demo scenes. Apart of the Azure Kinect sensor (aka K4A), the K4A-package supports the “classic” Kinect-v2 (aka Kinect for Xbox One) sensor, as well as Intel RealSense D400-series sensors.
Please note, this package is work in progress and issues are possible. The underlying Azure Kinect Sensor SDK is stable, but not mature enough yet, while the Body Tracking SDK is in preview state. In this regard, expect multiple updates and fixes over time. These updates will be available to all customers, free of any charge.
The avatar-demo scenes show how to utilize Kinect-controlled avatars in your scenes, gesture demo – how to use discrete and continuous user gestures in your projects, fitting room demos – how to overlay or blend the user’s body with virtual models, background removal demo – how to display user silhouettes on virtual background, point cloud demos – how to show the real environment or users as meshes in your scene, etc. Short descriptions of all demo-scenes are available in the online documentation.
This package works with Azure Kinect (aka Kinect for Azure, K4A), Kinect-v2 (aka Kinect for Xbox One) and Intel RealSense D400-series sensors. It can be used with all versions of Unity – Free, Plus & Pro.
How to run the demo scenes:
1. (Azure Kinect) Download and install the latest release of Azure-Kinect Sensor SDK. The download link is below. Then open ‘Azure Kinect Viewer’ to check, if the sensor works as expected.
2. (Azure Kinect) Follow the instructions on how to download and install the latest release of Azure-Kinect Body Tracking SDK and its related components. The link is below. Then open ‘Azure Kinect Body Tracking Viewer’ to check, if the body tracker works as expected.
3. (Kinect-v2) Download and install Kinect for Windows SDK 2.0. The download link is below.
4. (RealSense) Download and install RealSense SDK 2.0. The download link is below.
5. Import this package into new Unity project.
6. Open ‘File / Build settings’ and switch to ‘PC, Mac & Linux Standalone’, Target platform: ‘Windows’ & Architecture: ‘x86_64’.
7. Make sure that ‘Direct3D11’ is the first option in the ‘Auto Graphics API for Windows’-list setting, in ‘Player Settings / Other Settings / Rendering’.
8. Open and run a demo scene of your choice from a subfolder of the ‘AzureKinectExamples/KinectDemos’-folder. Short descriptions of all demo-scenes are available in the online documentation.
* The latest Azure Kinect Sensor SDK (v1.3.0) can be found here.
* The latest Azure Kinect Body Tracking SDK (v0.9.4) can be found here.
* Older releases of Azure Kinect Body Tracking SDK can be found here.
* Instructions how to install the body tracking SDK can be found here.
Please purchase the package at one of the following stores. In this case all future updates will be available to you, free of any charge:
* The K4A-asset may be purchased and downloaded in my online store.
* It may be purchased and downloaded at the Unity Asset store, as well.
* If you’d like to try the free K4A-asset first, you can find it here.
* The basic documentation is in the Readme-pdf file, in the package.
* The K4A-asset online documentation is available here.
* Many K4A-package tips, tricks and examples are available here.
* If you get syntax errors in console like “The type or namespace name ‘UI’ does not exist…”, please open the Package manager (menu Window / Package Manager) and install the ‘Unity UI’ package. The UI elements are extensively used in the K4A-asset demo scenes. Recently, for unknown reasons, Unity has decided to remove core packages (like the UI-package) from the standard distributions.
* If the Azure Kinect sensor cannot be started, because StartCameras()-method fails, please check again #6 in ‘How to run the demo scenes‘-section above.
* If you get a ‘Can’t create the body tracker’-error message, please check again #2 in ‘How to run the demo scenes‘-section above.
* If the body tracking stops working at run-time or the Unity editor crashes without notice, update to the latest version of the Body tracking SDK. This is a known bug in BT SDK v0.9.0.
* The RealSense-interface is in experimental state. Known issues are that body and user textures are missing, depth and color frames are out of sync, and that BT SDK v0.9.3 doesn’t seem to work with RS devices.
* If there are errors like ‘Shader error in [System 1]…’, while importing the K4A-asset, please note this is not really an error, but shader issues due to missing HDRP & VFX packages. You only need these packages for the Point-cloud demo. All other scenes should be started without any issues.
* If there are compilation errors in the console, or the demo scenes remain in ‘Waiting for users’-state, make sure you have installed the respective sensor SDKs, as well as the other needed components. Please also check, if the sensor is connected.
What’s New in Version 1.6:
1. Added BackgroundRemovalDemo4 scene, to show how to display virtual environment within the user’s silhouette.
2. Added BackgroundRemovalDemo5 scene, to demonstrate how to display the user’s silhouette in a 3d scene, according to the user’s distance to the sensor.
3. Upgraded K4A plugin to Azure Kinect Sensor SDK v1.3.0 & Body Tracking SDK v0.9.4. Updated sensor interfaces to support the new hand-related joints, as well as the joint tracking states.
4. Added ‘Ignore inferred joints’-setting to the KinectManager-component, to determine whether to consider or ignore the inferred joints.
5. Updated SceneMeshDemo & UserMeshDemo-scenes to undistort the mesh and to apply scene lighting (big thanks to Alan & Gianluca Martini).
