Welcome!
World Locking Tools for Unity provides a stable and reliable world-locked coordinate system, binding the virtual/holographic world to the physical world.
World Locking Tools take the burden of world-locking holograms off of the developer, as well as enabling scenarios that were previously unreachable. It currently supports the HoloLens family of devices via Unity's built-in VR support. Initial support for other platforms via Unity's new XR SDK plugin system is also available.
World Locking Tools locks the entire holograph space of your application to the physical world. A hologram put in position relative to physical world features will stay fixed relative to those features, as well as remaining fixed relative to other holograms.
World Locking Tools scale naturally with both the complexity and size of the scene. Large models, large collections of models, and multi-room environments are all handled gracefully.

A number of samples are contained in a sibling repo, World Locking Tools Samples. Be sure to have a look there for an instructive example. And if you don't find what you are looking for there, you are encouraged to submit a suggestion or even your own sample.
Easy and efficient
World Locking Tools is both powerful and easy to use. Furthermore, it strives to supply only as much as a specific application requires. Any World Locking Tools feature not required by an application will incur no cost in resources or performance.

These ideas are further explored in the conceptual guide. To complement the theoretical description, pragmatic samples are provided, along with how-to articles to walk through the steps involved in building applications using the World Locking Tools' stable and reliable coordinate system.
Further, reference materials for interfacing through script with World Locking Tools is included in the API Documentation.
