Hand.State

class Hand.State : Trackable.State

The representation of the current state of a Hand.

The state consists of an array of 182 floats (26 joints * 7 values per joint) which represent the poses of all hand joints. Each hand joint pose consists of 7 float values that represent rotation (x, y, z, w) and translation (x, y, z) as defined in Quaternion and Vector3 respectively. The order of the joints within the array follows the order in which the joints are defined in HandJointType.
