A composite floor panel includes a frame assembly having a base plate, a plurality of first lateral supports secured to the base plate, and a plurality of second lateral supports secured to the base plate. A request is received for a first two-dimensional view of a three-dimensional environment that identifies a first planar region associated with content within the three-dimensional environment. At the same time, the laser scanner produces separating line sections which are of hook-shaped configuration at least at one end so as to form a catching area in which the ends of the separating line sections of adjacent fields overlap.
