Unigine::Plugins::LeapMotion::Finger Struct

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
{
	enum
	{
		TYPE_THUMB = 0,	 // The thumb 
		TYPE_INDEX = 1,	 // The index or fore-finger 
		TYPE_MIDDLE = 2, // The middle finger 
		TYPE_RING = 3,	 // The ring finger 
		TYPE_PINKY = 4,	 // The pinky or little finger 
		FINGER_NUM_TYPES,
	};

	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.

struct Finger

Fields

  • enum TYPE -
    • TYPE_THUMB - thumb
    • TYPE_INDEX - index or fore finger
    • TYPE_MIDDLE - middle finger
    • TYPE_RING - ring finger
    • TYPE_PINKY - pinky or little finger
    • FINGER_NUM_TYPES - total number of finger types.
    For example, to specify the middle finger, write Finger::TYPE_MIDDLE.
  • int id - Identifier 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.
  • int type - Finger type. One of the Finger::TYPE_* values.
  • float length - Length of the finger, in meters.
  • float width - Width of the finger, in meters.
  • int is_extended - Value indicating if the finger is extended.
  • int is_valid - Value indicating if the finger contains valid tracking data.
  • Math::vec3 tip_position - Coordinates of the instantaneous position of the finger tip.
    Notice
    All coordinates are relative to the origin of the Leap Motion coordinate system.
  • Math::vec3 tip_velocity - Instantaneous velocity of the finger tip, in m/s.
    Notice
    All coordinates are relative to the origin of the Leap Motion coordinate system.
  • vec3 direction - Current pointing direction vector of the finger.
    Notice
    All coordinates are relative to the origin of the Leap Motion coordinate system.
  • Math::vec3 stabilized_tip_position - 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.
  • LeapMotion::Bone[] bones - Array of bones of the finger. Elements of the array can be accessed using Bone::TYPE values as indices.
