Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 12]

▼NWikitude
CCloudRecognitionService	CloudRecognitionService is used to send image(s) taken by the camera to the Cloud Recognition Service. The server will then do the hard work of trying to match the image with your targets in the specified cloud archive
CCloudRecognitionServiceResponse	The response received from the CloudRecognitionService after initiating a recognition request.
CFrame	Structure containing the pointer to frame data, as well as additional information about the frame.
CImageTarget	An image target contains information about a tracked target.
CImageTrackable	Image Trackables are used by Image Trackers to specify which augmentations correspond to which targets. It also provides information about tracking status
CImageTracker	Image Trackers are used to recognize image targets bundled in .wtc files by using a TargetCollectionResource or from the cloud by using a CloudRecognitionService
CInstantTarget	An instant target contains information about the tracked scene.
CInstantTrackable	Instant Trackables are used by Instant Trackers to specify which augmentations should be used during tracking. It also provides information about tracking status
CInstantTracker	Instant Trackers provide markerless 3D tracking of a scene, allowing to place augmentations anywhere in the real world. An Instant Tracker can be in two states: Initializing, during which the tracking origin can be set; and Tracking, during which the scene is being tracker
CObjectTarget	An object target contains information about a tracked target.
CObjectTrackable	Object Trackables are used by Object Trackers to specify which augmentations correspond to which targets. It also provides information about tracking status
CObjectTracker	Object Trackers are used to recognize and track objects defined in .wto files by using a TargetCollectionResource
CPlatformBase	Base class used for platform dependent compilation. For internal use only.
CPluginManager	The plugin manager allows you to get individual frames of the camera feed to do additional processing on it.
CRecognizedTarget	Base class for target classes. Intended for internal use only and should not be derived from.
CSDKBuildInformation	Encapsulates build information for the SDK. This information is only available when running on the device.
CTargetCollectionResource	Represents a resource that was initialized with a .wtc (Wikitude Target Collection) or .wto (Wikitude Object Collection) file. The file can be loaded either from the device, if it was stored in the StreamingAssets folder, or from a remote server. If the file was loaded from a server, no internet connection is required anymore after loading finished successfully
CTargetSource	Base class for TargetCollectionResource and CloudRecognitionService. Intended for internal use only and should not be derived from.
CTrackable	Base class for trackable classes. Intended for internal use only and should not be derived from.
CTrackableBehaviour	Trackables are used by trackers to update 3D objects in Unity based on tracked targets
CTrackerBehaviour	Base class for tracker classes. Intended for internal use only and should not be derived from.
CTrackerManager	Tracker manager handles messages from the native plugin. It is created and managed by the plugin and it should not be used directly.
CWikitudeCamera	The Wikitude camera handles the connection with the native plugins
