To use a template, simply drag any of the tracking templates into the scene from your project's assets. You can find Templates in your project's Assets folder,
Once imported, the relevant objects such as a Zappar Camera, Zappar Tracker and tracker dependencies will be added to your hierarchy.
The templates above are great for most use cases, and you may find they've got everything you need for your next AR project. That said, the Zappar library does provide a rich API that you can use should you require detailed control of the computer vision libraries.
