Edit

Gets the pose of a hand joint, expressed in the specified coordinate system.

bool TryGetJoint(SpatialCoordinateSystem const& coordinateSystem, HandJointKind const& joint, [Out] JointPose & jointPose);

public bool TryGetJoint(SpatialCoordinateSystem coordinateSystem, HandJointKind joint, out JointPose jointPose);

Public Function TryGetJoint (coordinateSystem As SpatialCoordinateSystem, joint As HandJointKind, ByRef jointPose As JointPose) As Boolean

Parameters

coordinateSystem: SpatialCoordinateSystem

The coordinate system in which to express the joint pose.

joint: HandJointKind

The hand joint kind to locate.

jointPose: JointPose

The pose to fill for the specified joint.

Returns

Boolean

bool

True if the hand can be located within the specified coordinate system; otherwise, false.

Remarks

The coordinate system is right-handed, with +y up, +x to the right, and -z forward.

All joints except for tip joints are interior to the hand. Finger joint poses represent the base of the named bone. Joints are oriented with forward (-z) pointing towards the tip of each finger, up (+y) pointing out of the back of the hand or finger, and right (+x) pointing perpendicular to forward and up.

This method will return false if the specified coordinate system cannot be located at the moment.
