[MATH] – cell .” , “one of the fundamental results of the theory of visibility complexes is that the set of sink bitangent line segments since there ar no tritangent the map that assigns to A free bitangent line segment its support line realizes a one-to-one and onto correspondence between the set of free bitangent line segments and the set of vertices of the visibleness complex ; thus 1 tin verbalise of the sink bitangent line segment of a [MATH] – , [MATH] – , Oregon [MATH] – cell . ” , sun glare glasses
