Unigine::Plugins::LeapMotion::Finger Struct

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.
