The Intersection Conics of Six Straight Lines
We investigate and visualize the manifold M of planes that intersect six straight lines of real projective three space in points of a conic section. It is dual to the apex-locus of the cones of second order that have six given tangents. In general M is algebraic of dimension two and class eight. It has 30 single and six double lines. We consider special cases, derive an algebraic equation of th...
متن کاملIndexing Straight-Line Programs∗
Straight-line programs offer powerful text compression by representing a text T [1, u] in terms of a context-free grammar of n rules, so that T can be recovered in O(u) time. However, the problem of operating the grammar in compressed form has not been studied much. We present the first grammar representation able of extracting text substrings, and of searching the text for patterns, in time o(...
متن کاملStraight Line Triangle Representations
A straight line triangle representation (SLTR) of a planar graph is a straight line drawing such that all the faces including the outer face have triangular shape. Such a drawing can be viewed as a tiling of a triangle using triangles with the input graph as skeletal structure. In this paper we present a characterization of graphs that have an SLTR. The charcterization is based on flat angle as...
متن کاملStraight-Line Drawing of Quadrangulations
This article introduces a straight-line drawing algorithm for quadrangulations, in the family of the face-counting algorithms. It outputs in linear time a drawing on a regular W×H grid such that W+H = n − 1 −∆, where n is the number of vertices and ∆ is an explicit combinatorial parameter of the quadrangulation.
متن کاملLinear Axis for Planar Straight Line Graphs
A linear axis is a straight line skeleton for a polygonal shape. The concept of a linear axis ε-equivalent to the medial axis has been introduced and studied for simple polygons and for those with holes. In this paper, we generalize the notions of a linear axis and of ε-equivalence to the case of planar straight line graphs. We show that for some graphs, a linear axis ε-equivalent to the medial...
