Unigine::LeapMotion::Finger Struct

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

This structure represents a finger of a hand and has the following set of properties:

type Finger type. One of the Finger::TYPE_* values.
id ID of the finger.
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.
length Length of the finger, in meters.
witdh Width of the finger, in meters.
is_extended Indicates whether this finger is extended (1).
is_valid Indicates whether this finger contains valid tracking data (1).
tip_position Coordinates of the instantaneous position of the finger tip.
stabilized_tip_position Coordinates of the finger tip position filtered and stabilized using velocity and past positions.
tip_velocity Instantaneous velocity of the finger tip, in m/s.
direction Current pointing direction vector of the finger.
bones Array of bones of the finger. Elements of the array can be accessed using Bone::TYPE_* values as indices.
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];
