This inheritance list is sorted roughly, but not completely, alphabetically:

[detail level 12]

CWikitude.CameraFrame	A class that contains color frames, along with their metadata.
CWikitude.CameraFramePlane	A single plane of image data.
CWikitude.CameraFrameRenderer	The CameraFrameRenderer is responsible for rendering the camera frame to the screen. If this is not desired, the script can simply be removed from the scene.
CWikitude.CloudRecognitionServiceResponse	The response received from the CloudRecognitionService after initiating a recognition request.
CWikitude.ColorCameraFrameMetadata	A struct that encapsulates additional information about color camera frames.
CWikitude.DeviceCamera	Controls the configuration and access to the physical camera on the device. If an input plugin is used instead, this script should be removed from the scene.
CWikitude.Error	Error class that encapsulates additional information. Used thought the SDK when something goes wrong.
CWikitude.IntrinsicsCalibration	Describes the physical properties of the camera.
CWikitude.LivePreview	The LivePreview components allows the Wikitude SDK to connect to various sources of image data inside the Unity Editor and enables all tracking features to be tested in Play Mode.
CWikitude.PlatformBase	Base class used for platform dependent compilation. For internal use only.
CWikitude.Plugin	Plugins can be used to get the camera frames from the SDK for additional processing. If the plugin has an input module, it can be used to feed camera frames to the SDK from other sources.
▼CWikitude.RecognizedTarget	Base class for target classes. Intended for internal use only and should not be derived from.
CWikitude.ImageTarget	An image target contains information about a tracked target.
CWikitude.ObjectTarget	An object target contains information about a tracked target.
CWikitude.SceneRenderer	This component is responsible for rendering the 3D scene in coordination with the camera frame renderer. If custom cameras are set up, this component should be added to them and the fields should mimic the values of the AR Camera's SceneRenderer component.
CWikitude.SDKBuildInformation	Encapsulates build information for the SDK.
CWikitude.SDKLicenseKey	Defines the License Key that should be used with the Wikitude SDK.
▼CWikitude.TargetSource	Base class for TargetCollectionResource and CloudRecognitionService. Intended for internal use only and should not be derived from.
CWikitude.CloudRecognitionService	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
CWikitude.TargetCollectionResource	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
▼CWikitude.Trackable	Base class for trackable classes. Intended for internal use only and should not be derived from.
CWikitude.ImageTrackable	Image Trackables are used by Image Trackers to specify which augmentations correspond to which targets. It also provides information about tracking status
CWikitude.ObjectTrackable	Object Trackables are used by Object Trackers to specify which augmentations correspond to which targets. It also provides information about tracking status
▼CWikitude.Tracker	Base class for tracker classes. Intended for internal use only and should not be derived from.
CWikitude.ImageTracker	Image Trackers are used to recognize image targets bundled in .wtc files by using a TargetCollectionResource or from the cloud by using a CloudRecognitionService
CWikitude.ObjectTracker	Object Trackers are used to recognize and track objects defined in .wto files by using a TargetCollectionResource
CWikitude.WikitudeSDK	The WikitudeSDK object handles the connection with the native plugins
