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#)
public struct Finger
{
public enum TYPE
{
THUMB = 0, // The thumb
INDEX = 1, // The index or fore-finger
MIDDLE = 2, // The middle finger
RING = 3, // The ring finger
PINKY = 4, // The pinky or little finger
NUM_TYPES,
};
public int id;
public int type;
public float length;
public float width;
public int is_extended;
public int is_valid;
public vec3 tip_position;
public vec3 tip_velocity;
public vec3 direction;
public vec3 stabilized_tip_position;
public Bone[] bones;
};Elements of the array of bones of the finger can be accessed using Bone.TYPE values as indices.

Fields
- enum TYPE -
- THUMB - thumb
- INDEX - index or fore finger
- MIDDLE - middle finger
- RING - ring finger
- PINKY - pinky or little finger
- NUM_TYPES - total number of finger types.
- int id - Identifier of the finger. NoticeFinger 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.
- vec3 tip_position - Coordinates of the instantaneous position of the finger tip.
NoticeAll coordinates are relative to the origin of the Leap Motion coordinate system.
- vec3 tip_velocity - Instantaneous velocity of the finger tip, in m/s.
NoticeAll coordinates are relative to the origin of the Leap Motion coordinate system.
- vec3 direction - Current pointing direction vector of the finger.
NoticeAll coordinates are relative to the origin of the Leap Motion coordinate system.
- vec3 stabilized_tip_position - Coordinates of the finger tip position filtered and stabilized using velocity and past positions.
NoticeAll 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.
