Unigine::LeapMotion::Finger Struct
| Header: | #include <LeapMotionInterface.h> |
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
The Finger structure is declared as follows:
All coordinates are relative to the origin of the Leap Motion coordinate system.
