Install VisionLib Packages in Unity

Prerequisites

To install the VisionLib UPM (Unity Package Manager) packages in Unity, you require a working Unity installation. We recommend using Unity 2021.3 LTS or higher.

Installing UPM Packages

Note: All package and file names do also contain their version number in semantic versioning e.g. VisionLib.SDK-Unity-3.0.0.tgz. For readability purposes, they are left out in the following steps.

• Download the VisionLib.SDK-Unity.zip from the customer area and extract it locally
• Import the tarball file VisionLib.SDK-Unity.tgz via Unity's Package Manager

Note: UPM package contents are not saved as files in the Unity project (only a reference to the tarball file is stored in Packages/package-lock.json). Therefore the location of the tarball file is important and moving or deleting it will break the dependencies of your Unity project. To prevent that and also include the package in your version control, you can save it to the Packages folder of your project and import it from that location. This will result in a relative path in your package-lock.json. We recommend using git-lfs.

• At this point, you are ready to go, as the UPM package contains all necessary scripts and prefabs to develop VisionLib applications
• The according assets will appear in the project view under Packages / VisionLib SDK

Adding Examples

• To understand how the VisionLib SDK can be used within Unity, take a look at the example scenes and assets inside the VisionLib.SDK.Examples-Unity.unitypackage, which needs to be imported additionally.
• To do that, drag the package into the project view or select Assets > Import Package > Custom Package (do not use the Package Manager in this case).
• This will add a StreamingAssets and VisionLib Examples folder directly below Assets.

Adding an extension package

If the HoloLens or ARFoundation functionality is required, the according extension package can be imported in addition to the core VisionLib SDK.

• Within the unpacked VisionLib.SDK-Unity.zip file, open the Extensions folder, which contains the HoloLens and ARFoundation extension packages.
• Import the tarball file VisionLib.SDK.HoloLens-Unity.tgz / VisionLib.SDK.ARFoundation-Unity.tgz via Unity's Package Manager
• Optional: Import the VisionLib.SDK.HoloLens.Examples-Unity.unitypackage / VisionLib.SDK.ARFoundation.Examples-Unity.unitypackage by dragging and dropping the package into the project view or select Assets > Import Package > Custom Package (do not use the Package Manager in this case)

Note: The VisionLib SDK -HoloLens and -ARFoundation package do have additional dependencies to Plugins from Unity. When adding the package to the Package Manager, the dependencies for ARFoundation are installed automatically. For HoloLens, some packages have to be installed manually (see Deploying to HoloLens).
