The hierarchy of joints and their names.
Declaration
class ARSkeletonDefinitionOverview
A skeleton definition establishes the relationship of joints that make up a 3D or 2D body’s skeleton, in which joints connect to other joints to compose a single skeleton in a parent-child hierarchy. Use parentIndices to identify the hierarchy for a given skeleton definition.
ARKit names particular joints that are crucial to body tracking. You can access named joints by calling indexForJointName: and passing in one of the available jointNames identifiers.
