Methods

Name	Type	Summary
latestCameraSample	(image: CVPixelBuffer, intrinsics: NSDKCameraIntrinsics, pose: NSDKCameraExtrinsics, orientation: NSDKScreenOrientation, timestamp: UInt64)?	Returns the most recent camera sample, if available. - Returns: A tuple containing: - image: A retained CVPixelBuffer representing the captured image. - intrinsics: Camera intrinsic parameters for the image. - pose: The pose (extrinsics) of the camera associated with the image. - orientation: The device orientation of the camera associated with the image. - timestamp: Camera timestamp in milliseconds.
latestCompassSample	NSDKFrameData.CompassData?	Returns the most recent compass (heading) sample, if available.
latestDepthMapSample	(image: CVPixelBuffer, confidence: CVPixelBuffer?, intrinsics: NSDKCameraIntrinsics, pose: NSDKCameraExtrinsics, orientation: NSDKScreenOrientation, timestamp: UInt64)?	Returns the most recent platform depth sample, if available. - Returns: A tuple containing: - image: A retained CVPixelBuffer representing the captured image. - confidence: A pixel buffer containing the confidence level for each depth value in the image. - intrinsics: Camera intrinsic parameters for the image. - pose: The pose (extrinsics) of the camera associated with the image. - orientation: The device orientation of the camera associated with the image. - timestamp: Camera timestamp in milliseconds.
latestGpsSample	NSDKFrameData.GpsData?	Returns the most recent GPS sample, if available.
latestTrackingStateSample	NsdkTrackingState	Returns the most recent VIO tracking state report
