XRSPACE_LOCAL: string = 'local'

Local - represents a tracking space with a native origin near the viewer at the time of creation. The exact position and orientation will be initialized based on the conventions of the underlying platform. When using this reference space the user is not expected to move beyond their initial position much, if at all, and tracking is optimized for that purpose. For devices with 6DoF tracking, local reference spaces should emphasize keeping the origin stable relative to the user's environment.
