In this paper we study a number of fundamental combinatorial and algorithmic problems involving arrangements of n lines in three-dimensional space. Our main results include: 1. A tight Θ(n2) bound on the maximum combinatorial description complexity of the set of all oriented lines that have specified orientations relative to the n given lines. 2. A similar bound of Θ(n3) for the complexity of the set of all lines passing above the n given lines. 3. A preprocessing procedure using O(n2+ε) time and storage, for any ε &gt; 0, that builds a structure supporting O(logn)-time queries for testing if a line lies above all the given lines. 4. An algorithm that tests the &quot;towering property&quot; in O(n4/3+ε) time, for any ε &gt; 0: do n given red lines lie all above n given blue lines? The tools used to obtain these and other results include Plücker coordinates for lines in space and ε-nets for various geometric range spaces."}],"type":"journal_article","publist_id":"2100","article_type":"original","publisher":"Springer","day":"01","page":"428 - 447","issue":"5","intvolume":"        15","date_created":"2018-12-11T12:06:31Z","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0178-4617"]},"article_processing_charge":"No","title":"Lines in space: Combinatorics and algorithms","acknowledgement":"Work on this paper by Bernard Chazelle has been supported by NSF Grant CCR-87-00917.
