The Tobii XR SDK aims to provide device agnostic access to eye tracking data to allow development for headsets from many different hardware vendors and is not limited to. SDKs Tools Ocumen Samples Showcases Demos and prototypes can be downloaded directly from our Explore page. Here, you can get started with the Tobii XR SDK for Unity, download our Unity Samples, use our tools to simplify your development process or read the documentation. From there, the provider must register with all subsystems it intends to implement. Downloads Downloads On this page you can access our SDK components and tools. The entry point is the UnityPluginLoad method. Providers conform to the Unity native plug-in interface, with some additional lifecycle support built on top. Some subsystems can allow multiple providers to be active at a time, but others might be mutually exclusive. One subsystem can have multiple providers. ProviderĪ provider is the native implementation of a subsystem. The subsystem itself has its own lifecycle: it can be started, stopped, and shut down. Scripting code interacts with these instances in order to communicate with the subsystem. When Create is called on a subsystem descriptor, this creates a subsystem instance. More info See in Glossary.įor more information, see the Runtime discovery and activation of subsystems page. Works with Varjo, but openvrapi.dll must be removed either from Varjo or OpenVR plugin for builds. A Create method activates the subsystem and provides an instance of it to the user’s scripts A piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. Make sure to initialize Varjo XR SDK before OpenXR, otherwise the Unity project will run in OpenXR compatibility mode instead of native Varjo mode on Varjo headsets. This comes from a manifest file and is accessed via a C# interface. Common engine code which handles communicating with the C# interface, the native interface, and the rest of the engineĪ subsystem descriptor is metadata about a subsystem which can be inspected before loading or initializing a subsystem.A native interface that multiple backends (Providers) implement via dynamic libraries.User applications can select and activate providers at runtime. The XR SDK package allows multiple backends (called “providers”) to implement a single engine feature (called a “subsystem”) in Unity. To download XR SDK, you must sign up for access on this page. The Unity XR SDK is aimed at specialist users who want to develop their own XR providers that work with Unity.
