Unigine::LeapMotion::Finger Struct

Header:

#include <LeapMotionInterface.h>

Variables:

Name	Description
Finger::TYPE_THUMB	Thumb.
Finger::TYPE_INDEX	Index finger.
Finger::TYPE_MIDDLE	Middle finger.
Finger::TYPE_RING	Ring finger.
Finger::TYPE_PINKY	Pinky finger.
Finger::FINGER_NUM_TYPES	Total number of finger types.

Notice

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. 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.
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.

Notice

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];
};
