SIAM Journal on Numerical Analysis Cited by: This substitution introduces numerical errors in the computations that may lead to nonrobust behavior in the implementation, such as infinite loops or segmentation faults.
There are various approaches in the the literature addressing the problem of nonrobustness in geometric computations; see [ 9 ] for a survey. The book combines topics in mathematics (geometry and topology), computer science (algorithms), and engineering (mesh generation).
The motivation for these topics is the difficulty, both conceptually and in the technical execution, of combining elements of combinatorial and of numerical algorithms.
Mesh generation is a topic where a meaningful combination of these different approaches to problem Cited by: This book contains tutorial surveys and original research contributions in geometric computing, modeling, and reasoning.
Highlighting the role of algebraic computation, it covers: surface blending, implicitization, and parametrization; automated deduction with Clifford algebra and in real geometry; and exact geometric computation.
Basic techniques, advanced methods, and new findings are. It also considers computations on geometric point-sets, which are neither robust nor reliable in processing with standard methods. The authors provide two effective tools for obtaining correct results: (a) interval arithmetic, and (b) ESSA the new powerful algorithm which improves many geometric computations and makes tAuthor: H Ratschek and J Rokne.

Basic techniques, advanced methods, and new findings are presented coherently, with many examples and illustrations. Using this book the reader will easily cross the frontiers of symbolic computation, computer aided geometric design, and automated reasoning. Geometric computation software tends to be fragile and fails occasionally.
This robustness problem is rooted in the difficulty of making unambiguous decisions about incidence and nonincidence, fundamentally impairing layering the geometry software by: Geometric computations with interval and new robust methods: applications in computer graphics, GIS and computational geometry.
[H Ratschek; J Rokne] -- This undergraduate and postgraduate text will familiarise readers with interval arithmetic and related tools to gain reliable and validated results and logically correct decisions for a variety of. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): A new technique, the hidden variable method, is described for the creation of robust geometric algorithms: algorithms which can be implemented with absolute reliability using rounded finite precision arithmetic.
The specific application given here is an algorithm for computing arrangements of line segments in two. The problems of accuracy and robustness in geometric computation Abstract: Practical implementation of geometric operations remains error-prone, and the goal of implementing correct and robust systems for carrying out geometric computation remains by: Robust watermarking against geometric attacks using partial calculation of radial moments and interval phase modulation.
a new robust watermarking scheme, which can effectively resist common geometric attacks, is proposed. the performance of the proposed method against geometric transformation has been illustrated and by: We propose a new paradigm for robust geometric computations that complements the classical ﬁxed precision paradigm (interval geometry, "-geometry and stable algorithms) and the exact geometric computation paradigm.
We provide a framework where we Author: Jeff Erickson, Ivor van der Hoog, Tillmann Miltzow. Karmakar S and Bhunia A () A new multi-section based technique for constrained optimization problems with interval-valued objective function, Applied Mathematics and Computation,(), Online publication date: 1-Dec available for all data is the geometrical interval classification method which was called “smart quantiles” when it was originally introduced in the Esri Geostatistical Analyst extension.
This classification method was used for visualizing continuous data and to provide an alternative to the Natural Breaks (Jenks), quantiles, and really any Author: Charlie Frye. The crux is to have access to robust and e cient data structures and algorithms to represent and analyze the pos-sibly highly nonlinear underlying geometric structure of data.
