Joints and JointCollection are the building blocks of Skeleton. Each Skeleton object has a property named Joints, which is a type of
JointCollection and contains all the traceable joints. JointCollecton contains a set of Joints and can be accessed by specifying the index value. When you pass JointType to get the Joint point, it will return the Joint object.
Let's consider you have an object of a tracked skeleton as follows:
Skeleton skeleton = (from trackskeleton in totalSkeleton where trackskeleton.TrackingState == SkeletonTrackingState.Tracked select trackskeleton).FirstOrDefault();
In the previous code, the skeleton object now contains Joints in the form of JointCollection. Now to get the reference of a particular joint type, you need to pass the type within the collection as shown in the following example for the Head JointType:
Joint headJoint= skeleton.Joints[JointType.Head]);
headJoint now refers to HeadJoint of the skeleton object, with...
