CUTTINGS AND APPLICATIONS [PDF]
International Journal of Computational Geometry & Applications, 1995 We prove a general lemma on the existence of (1/r)-cuttings of geometric objects in Ed that satisfy certain properties. We use this lemma to construct (1/r)-cuttings of small size for arrangements of line segments in the plane and arrangements of triangles in 3-space; for line segments in the plane we obtain a cutting of size O(r+Ar2/n2), and for ...
