Detailed Description

APIs for generating and using area description files (ADF) and trajectories.

Area description can be created by recording a Tango dataset and running Tango3DR_AreaDescription_createFromDataset. From there, users can extract an accurate device trajectory for the dataset session, which can be used for building more accurate meshes and textures in post-process.

Tango3DR_Status Tango3DR_AreaDescription_destroy ( Tango3DR_AreaDescription area_description )

Destroy a previously created area description

Parameters:

area_description Handle to a previously-created area description.

Returns:: TANGO_3DR_SUCCESS on successfully destroying the area description. Returns TANGO_3DR_INVALID if area description is NULL.

Tango3DR_Status Tango3DR_AreaDescription_loadFromAdf	(	const char *const	path,
		Tango3DR_AreaDescription *	area_description
	)

Load an area description from an ADF (area description file).

Parameters:

path	Path to the ADF.
area_description	On successful return, this will be filled with a freshly allocated Tango3DR_AreaDescription. After use, free this by calling Tango3DR_AreaDescription_destroy().

Returns:: TANGO_3DR_SUCCESS on successfully loading an area descruption, TANGO_3DR_INVALID if the parameters are not valid, and TANGO_3DR_ERROR if loading failed.

Tango3DR_Status Tango3DR_AreaDescription_saveToAdf	(	Tango3DR_AreaDescription	area_description,
		const char *const	path
	)

Save an area description to an ADF (area description file).

Parameters:

area_description	Area description to be saved.
path	Output path.

Returns:: TANGO_3DR_SUCCESS on successfully saving the area description, TANGO_3DR_INVALID if any of the arguments are NULL, and TANGO_3DR_ERROR if some other error occurred.

Tango3DR_Status Tango3DR_getPoseAtTime	(	const Tango3DR_Trajectory	trajectory,
		const double	timestamp,
		Tango3DR_Pose *	tango_pose
	)

Retrieves the pose at a given time from a trajectory.

Parameters:

trajectory	The handle to a Tango trajectory.
timestamp	The timestamp, in seconds, at which to query the pose.
tango_pose	A pointer to the output pose. Must be within the start and end time of the trajectory.

Returns:: TANGO_3DR_SUCCESS on success, TANGO_3DR_INVALID if the parameters are not valid, and TANGO_3DR_ERROR if the timestamp queried is not in the range of the trajectory.

Tango3DR_Status Tango3DR_Trajectory_createFromAreaDescription	(	const Tango3DR_AreaDescription	area_description,
		Tango3DR_Trajectory *	trajectory
	)

Create a trajectory from a an area description.

Parameters:

area_description	a handle to an area description.
area_description	On successful return, this will be filled with a freshly allocated Tango3DR_Trajectory. After use, free this by calling Tango3DR_Trajectory_destroy().

Tango3DR_Status Tango3DR_Trajectory_destroy ( Tango3DR_Trajectory trajectory )

Destroy a previously created trajectory.

Parameters:

trajectory Handle to a previously created trajectory.

Returns:: TANGO_3DR_SUCCESS on successfully destroying the trajectory. Returns TANGO_3DR_INVALID if trajectory is NULL.

Tango3DR_Status Tango3DR_Trajectory_getEarliestTime	(	const Tango3DR_Trajectory	trajectory,
		double *	timestamp
	)

Retrieves the earliest time available in a trajectory.

Parameters:

trajectory	The handle to a Tango trajectory.
timestamp	A pointer to the output timestamp. Timestamp is in seconds.

Returns:: TANGO_3DR_SUCCESS on success, TANGO_3DR_INVALID if the parameters are not valid, TANGO_3DR_ERROR if the trajectory is empty.

Tango3DR_Status Tango3DR_Trajectory_getLatestTime	(	const Tango3DR_Trajectory	trajectory,
		double *	timestamp
	)

Retrieves the latest time available in a trajectory.

Parameters:

trajectory	The handle to a Tango trajectory.
timestamp	A pointer to the output timestamp. Timestamp is in seconds.

Returns:: TANGO_3DR_SUCCESS on success, TANGO_3DR_INVALID if the parameters are not valid, TANGO_3DR_ERROR if the trajectory is empty.
