 Azure Object Anchors enables an application to detect an object in the physical world using a 3D model and estimate its 6DoF pose. The 6DoF (6 degrees of freedom) pose is defined as a rotation and translation between a 3D model and its physical counterpart, the real object.
 
 Azure Object Anchors is composed of a service for model conversion and a runtime client SDK for HoloLens. The service accepts a 3D object model and outputs an Azure Object Anchors model. The Azure Object Anchors model is used along with the runtime SDK to enable a HoloLens application to load an object model, detect, and track instance(s) of that model in the physical world.
