Detailed Description

Driver that can wrap multiple devices, for example to override tracking.

Function Documentation

struct xrt_device* multi_create_tracking_override	(	enum xrt_tracking_override_type	override_type,
		struct xrt_device *	tracking_override_target,
		struct xrt_device *	tracking_override_tracker,
		enum xrt_input_name	tracking_override_input_name,
		struct xrt_pose *	offset
	)

Create a device that takes ownership of the target device and mimics it.

Does not take ownership of the tracker device, one can be assigned to multiple targets.

The pose provided by get_tracked_pose will be provided by the tracker device.

Parameters

override_type	The kind of override this wrapper device will provide.
tracking_override_target	An existing device that will be mimiced by the created device.
tracking_override_tracker	An existing device that will be used to provide tracking data.
tracking_override_input_name	The input name of the tracker device. XRT_INPUT_GENERIC_TRACKER_POSE for generic trackers.
offset	A static offset describing the real world transform from the "tracked point" of the target device to the "tracked point" of the tracker device. A tracking sensors attached .1m above the HMD "center" sets y = 0.1.
