Unigine::Plugins::LeapMotion::Finger Struct

Header: #include <UnigineLeapMotion.h>
Notice
LeapMotion plugin must be loaded.

This structure represents a finger of a hand. All coordinates are relative to the origin of the Leap Motion coordinate system.

The Finger structure is declared as follows:

Source code (C++)
struct Finger
{
	int id;
	int type;
	float length;
	float width;
	int is_extended;
	int is_valid;
	Unigine::Math::vec3 tip_position;
	Unigine::Math::vec3 tip_velocity;
	Unigine::Math::vec3 direction;
	Unigine::Math::vec3 stabilized_tip_position;

	Bone bones[Bone::BONE_NUM_TYPES];
};

Elements of the array of bones of the finger can be accessed using Bone::TYPE_* values as indices.

Enums

TYPE#

NameDescription
TYPE_THUMB = 0Thumb.
TYPE_INDEX = 1Index finger.
TYPE_MIDDLE = 2Middle finger.
TYPE_RING = 3Ring finger.
TYPE_PINKY = 4Pinky finger.
FINGER_NUM_TYPES = Total number of finger types.

Members


int getType ( ) #

Returns the type of the finger.

Return value

Finger type. One of the Finger::TYPE_* values.

int getId ( ) #

Returns the ID of the finger.
Notice
Finger IDs are assigned based on the hand ID. If a hand has an ID of "5", then its fingers are assigned IDs 50 to 55, ordered from thumb to pinky.

Return value

Finger ID.

float getLength ( ) #

Returns the length of the finger, in meters.

Return value

Length of the finger, in meters.

float getWidth ( ) #

Returns the width of the finger, in meters.

Return value

Width of the finger, in meters.

vec3 getTipPosition ( ) #

Returns the coordinates of the instantaneous position of the finger tip.
Notice
All coordinates are relative to the origin of the Leap Motion coordinate system.

Return value

Coordinates of the instantaneous position of the finger tip.

vec3 getStabilizedTipPosition ( ) #

Returns the coordinates of the finger tip position filtered and stabilized using velocity and past positions.
Notice
All coordinates are relative to the origin of the Leap Motion coordinate system.

Return value

Coordinates of the finger tip position filtered and stabilized using velocity and past positions.

vec3 getTipVelocity ( ) #

Returns the instantaneous velocity of the finger tip, in m/s.
Notice
All coordinates are relative to the origin of the Leap Motion coordinate system.

Return value

Instantaneous velocity of the finger tip, in m/s.

vec3 getDirection ( ) #

Returns the current pointing direction vector of the finger.
Notice
All coordinates are relative to the origin of the Leap Motion coordinate system.

Return value

Current pointing direction vector of the finger.

int isExtended ( ) #

Returns a value indicating if the finger is extended.

Return value

1 if the finger is extended; otherwise, 0.

int isValid ( ) #

Returns a value indicating if the finger contains valid tracking data.

Return value

1 if the finger contains valid tracking data; otherwise, 0.
