- 26. AR Session The AR Session controls the lifecycle of an AR experience, enabling or disabling AR on the target platform.
- 27. AR Subsystem Manager AR Subsystems Plane Subsystem Camera Subsystem Others Subsystem ... SDK Plane Provider SDK Camera Provider Others Provider ...
- 28. AR Subsystem Manager This manager governs the life-cycles of multiple AR-related subsystems and provides higher level abstractions and utilities for managing and using the AR-related subsystems.
- 29. AR Session Origin The purpose of the ARSessionOrigin is to transform trackable features (such as planar surfaces and feature points) into their final position, orientation, and scale in the Unity scene.
- 30. Camera The Camera, which will be used to render any trackables you wish to visualize, must be a child of the ARSessionOrigin.
- 31. Tracked Pose Driver This setup allows the camera's local space to match the AR "session space".
- 32. AR Camera Manager The ARCameraManager enables camera features, such as textures representing the video feed and controls light estimation modes.
- 33. AR Camera Background If you want to render the device's color camera texture to the background, you need to add an ARCameraBackground component to a camera.
- 34. AR Raycast Manager Also known as hit testing, raycasting allows you to determine where a ray (defined by an origin and direction) intersects with a trackable. The current raycast interface only tests against planes and points in the point cloud.
- 36. Others Managers Each of these manager creates GameObjects for each detected trackable. The generated GameObjects are parented to a special GameObject under the ARSessionOrigin, accessible via ARSessionOrigin.trackablesParent.
- 37. Trackables Manager Trackable Component has TrackableId? ARPlaneManager ARPlane yes ARPointCloudManager ARPointCloud no ARReferencePointMana ger ARReferencePoint yes Each trackable component stores information about the trackable, but does not visualize it. Its Transform is updated by its manager whenever the AR device reports an update.
- 38. Trackables Events Event Description updated Invoked when a plane is updated. removed Invoked when a plane is about to be removed. boundaryChanged Invoked when the boundary points change by more than ARPlane.vertexChangedThreshold. If you want to visualize the mesh, subscribe to this event. ARPlane
- 39. Trackables Events Event Description updated Invoked when the point cloud is updated. ARPointCloud
- 40. Trackables Events Event Description updated Invoked when the reference point's Pose or TrackingState changes. ARReferencePoint
