The example shows how to manage a thumb with the Thumbclass.

// Create a thumb tip joint with the specified 2D position and 
// 3D position.
FingerJoint thumbTip = new FingerJoint
(
    FingerJointType.ThumbTip,
    new Vector2(3, 3),
    new Vector3(0.3f, 0.3f, 0.3f),
    new Quaternion()
);

// Create a thumb IP joint with the specified 2D position and 
// 3D position.
FingerJoint thumbIP = new FingerJoint
(
    FingerJointType.ThumbIP,
    new Vector2(3, 3),
    new Vector3(0.3f, 0.3f, 0.3f),
    new Quaternion()
);

 // Create a thumb with the specified thumb joints.
 Thumb thumb = new Thumb
 (
     new Dictionary<FingerJointType, FingerJoint> 
     {
         { FingerJointType.ThumbTip, thumbTip },
         { FingerJointType.ThumbIP, thumbIP }
     }
