Function Documentation

visualization_msgs::Marker createFingerLines	(	const leap_motion::Human::ConstPtr &	human,
		std::string	hand_ns,
		std::string	finger_ns,
		unsigned int	id,
		leap_motion::Bone	current_bone
	)

Adds lines between the tips of the bones.

Takes a pointer to human.msg, and a bone.msg. Using that information adds lines between the tips of the bones.

Parameters:

human	Pointer to the received Human.msg
hand_ns	Used to create a unique namespace
finger_ns	Used to create a unique namespace
current_bone	The bone that will be represented as a line.

visualization_msgs::Marker createHandOutline	(	const leap_motion::Human::ConstPtr &	human,
		std::string	hand_ns,
		unsigned int	id,
		leap_motion::Hand	current_hand
	)

Creates a representation of palm.

Takes a pointer to human.msg, and a hand.msg. Using that information adds draw lines between fingers to create a palm.

Parameters:

human	Pointer to the received Human.msg
hand_ns	Used to create a unique namespace
finger_ns	Used to create a unique namespace
current_hand	The hand from which the palm will be created

Definition at line 113 of file lmc_visualizer_node.cpp.

visualization_msgs::Marker createJointMarker	(	const leap_motion::Human::ConstPtr &	human,
		std::string	hand_ns,
		std::string	finger_ns,
		unsigned int	id,
		geometry_msgs::Pose	location
	)

Adds circles at the intersection of bones.

Takes a pointer to human.msg, and a start of a bone. Using that information creates a sphere visualization marker that will later be appended to a marker array.

Parameters:

human	Pointer to the received Human.msg
hand_ns	Used to create a unique namespace
finger_ns	Used to create a unique namespace
location	Tip position of a bone object

Definition at line 27 of file lmc_visualizer_node.cpp.

visualization_msgs::Marker createPalmPosition	(	const leap_motion::Human::ConstPtr &	human,
		std::string	hand_ns,
		unsigned int	id,
		geometry_msgs::Point	centre_point
	)

Represents the midpoint of the palm.

Takes a pointer to human.msg, and pose the the centre point of the palm. Using that information creates a sphere at that location.

Parameters:

human	Pointer to a received Human.msg
hand_ns	Used to create a unique namespace
id	A unique id to the created marker
centre_point	The palm centre of a hand

Definition at line 216 of file lmc_visualizer_node.cpp.

void createVisualization	(	visualization_msgs::MarkerArray *	marker_array,
		const leap_motion::Human::ConstPtr &	human,
		leap_motion::Hand	hand,
		std::string	hand_ns,
		uint8_t	hand_id
	)

Creates a visualization of an entire hand from he wrist up.

Using the given information calls out different functions to create a visualization of a detected hand for displaying in Rviz.

Parameters:

marker_array	An array into which all created markers will be added
human	Pointer to a received Human.msg
hand	A hand.msg from which the hand visualization will be created.
hand_ns	Used to create a unique namespace
hand_id	A unique id to the create markers

Definition at line 259 of file lmc_visualizer_node.cpp.

void frameCallback ( const leap_motion::Human::ConstPtr & human )

Called when a new Human.msg is received.

Parameters:

human Pointer to thr received Human.msg

int main	(	int	argc,
		char **	argv
	)
