Insertion and deletion of nodes are local processes. They just update the structures involved in this step. ChanDC convex hull demo Computational Geometry - This is a project I implemented in Java for the Computational Geometry course here at Hopkins. It implements two algorithms for segments intersection: the obvious one (every two segments are cheked for intersection) -on the left- and Balaban's algorithm -on the right-. The first one has an asimptotic running time of O(n2); the second one has an asimptotic running time of O(n log2(n)+k) where n is the number of segments and k is the number of intersection points. Computational Geometry Applet - This applet illustrates several pieces of code from Computational Geometry in C (Second Edition) by Joseph O'Rourke . The C code in the book has been translated as directly as possible into Java.

Options Qhull Qhull computes convex hulls, Delaunay triangulations, halfspace intersections about a point, Voronoi diagrams, furthest-site Delaunay triangulations, and furthest-site Voronoi diagrams. It runs in 2-d, 3-d, 4-d, and higher dimensions. It implements the Quickhull algorithm for computing the convex hull. Qhull handles roundoff errors from floating point arithmetic. It computes volumes, surface areas, and approximations to the convex hull. Qhull does not support constrained Delaunay triangulations, triangulation of non-convex surfaces, mesh generation of non-convex objects, or medium-sized inputs in 9-D and higher.

92. HYPERBOLIC GEOMETRY convexity in hyperbolic geometry. We begin with a definition which holds in any geometry with a notion of segments. definition A http://www.maths.gla.ac.uk/~wws/cabripages/hyperbolic/convexity.html

convexity in hyperbolic geometry We begin with a definition which holds in any geometry with a notion of segments. definition A subset S of the disk D is convex S , the segment AB lies in S In hyperbolic geometry, this means that the entire hyperbolic segment AB is in S Note that hyperbolic transformations map segments to segments, so convexity is a hyperbolic property. As usual, we will take advantage of this to simplify our diagrams, usually by moving A to the centre of the disk. We shall consider regions bounded by segments of i-lines. We observe that we can add the boundary points in D to a convex region to get a larger convex set. We shall often consider this larger set. First, some results which are true in both euclidean and hyperbolic geometry. Lemma 1 If S and T are convex, then so is S n T proof If A and B are in S n T , then they are in S so the segment AB is in S Similarly, segment AB is in T , and hence it is in S n T Lemma 2 If S is the interior of a circle K, then S is convex. proof If A and B are in S , then the line L = AB cuts K exactly twice.
