Download or read book Hidden Surface Removal Through Object Space Decomposition written by Robert Monroe Simmons and published by . This book was released on 1982 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hidden surface removal is a computer graphics problem involving a great deal of computation. The problem involves two facets: determining which objects should appear in front of others (prioritization), and elimination of invisible portions of the objects through geometric calculations. Prioritization is accomplished using object space decomposition, which divides object space in a binary fashion such that the objects in a scene (or critical portions of those objects) occupy unique sub-volumes of the object space. An octal-tree is used to map the decomposition, and a simple traversal of the tree, with minor interruptions for more sophisticated decision-making, results in a stream of objects in priority order. The second phase of the hidden surface problem, removal of invisible portions of objects, often requires a great deal of computation. Parallel processing offers potential for savings in response time, and the second part of this thesis investigates a number of algorithms which attempt to take advantage of inherent concurrency. Three algorithms are presented: a quad-tree image space decomposition algorithm, a purely geometric algorithm, and an algorithm which combines ideas from the first two. (Author).

This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains mainly a selection of papers that were presented at the International Workshop on High Performance Computing/or Computer Graphics and Visualisation, held in Swansea, United Kingdom on 3-4 July 1995. The workshop was sponsored by the HEFCWI Initiative on ·Parallel Computing - Foundations and Applications·, and it has provided the international computer graphics community with a platform for: • assessing and reviewing the impact of the development of high performance computing on the progress of computer graphics and visualisation; • presenting the current use of high performance computing architecture and software tools in computer graphics and visualisation, and the development of parallel graphics algorithms; • identifying potential high performance computing applications in computer graphics and visualisation, and encouraging members of the graphics community to think about their problems from the perspective of parallelism. The book is divided into six sections. The first section, which acts as the introduction of the book, gives an overview of the current state of the art It contains a comprehensive survey, by Whitman, of parallel algorithms for computer graphics and visualisation; and a discussion, by Hansen, on the past, present and future high performance computing applications in computer graphics and visualisation. The second section is focused on the design and implementation of high performance architecture, software tools and algorithms for surface rendering.

This book was released on 2012-12-06 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algebraic Geometry and its Applications will be of interest not only to mathematicians but also to computer scientists working on visualization and related topics. The book is based on 32 invited papers presented at a conference in honor of Shreeram Abhyankar's 60th birthday, which was held in June 1990 at Purdue University and attended by many renowned mathematicians (field medalists), computer scientists and engineers. The keynote paper is by G. Birkhoff; other contributors include such leading names in algebraic geometry as R. Hartshorne, J. Heintz, J.I. Igusa, D. Lazard, D. Mumford, and J.-P. Serre.

Download or read book Computer Architectures for Spatially Distributed Data written by Herbert Freeman and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: These are the proceedings of a NATO Advanced Study Institute (ASI) held in Cetraro, Italy during 6-17 June 1983. The title of the ASI was Computer Arehiteetures for SpatiaZZy vistributed Vata, and it brouqht together some 60 participants from Europe and America. Presented ~ere are 21 of the lectures that were delivered. The articles cover a wide spectrum of topics related to computer architecture s specially oriented toward the fast processing of spatial data, and represent an excellent review of the state-of-the-art of this topic. For more than 20 years now researchers in pattern recognition, image processing, meteorology, remote sensing, and computer engineering have been looking toward new forms of computer architectures to speed the processing of data from two- and three-dimensional processes. The work can be said to have commenced with the landmark article by Steve Unger in 1958, and it received a strong forward push with the development of the ILIAC III and IV computers at the University of Illinois during the 1960's. One clear obstacle faced by the computer designers in those days was the limitation of the state-of-the-art of hardware, when the only switching devices available to them were discrete transistors. As aresult parallel processing was generally considered to be imprae tieal, and relatively little progress was made.

Download or read book Computer Graphics written by Tosiyasu L. Kunii and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the design of any visual objects, the work becomes much easier if previous designs are utilized. Computer graphics is becoming increasingly important simply because it greatly helps in utilizing such previous designs. Here, "previous designs" signifies both design results and design procedures. The objects designed are diverse. For engineers, these objects could be machines or electronic circuits, as discussed in Chap. 3, ''CA~/CAM. '' Physicians often design models of a patient's organs from computed tomography images prior to surgery or to assist in diagnosis. This is the subject of Chap. 8, "Medical Graphics. " Chapter 7, "Computer Art," deals with the way in which artists use computer graphics in creating beautiful visual images. In Chap. 1, "Computational Geometry," a firm basis is provided for the definition of shapes in designed objects; this is a typical technical area in which computer graphics is constantly making worldwide progress. Thus, the present volume, reflecting international advances in these and other areas of computer graphics, provides every potential or actual graphics user with the essential up-to-date information. There are, typically, two ways of gathering this current information. One way is to invite international authorities to write on their areas of specialization. Usually this works very well if the areas are sufficiently established that it is possible to judge exactly who knows what. Since computer graphics, however, is still in its developmental stage, this method cannot be applied.

Available in PDF, EPUB and Kindle. Book excerpt: We present three applications of this general technique: (i) For disks (or balls in space) we have U(n) = O(n), thus the visibility map can be computed in time O((n + k)log2 n). (ii) For 'fat' triangles (where each internal angle is at least some fixed [theta] degrees) we have U(n) = O(n loglog n) and the algorithm runs in time O((n loglog n + K)log2n). (iii) The method also applies to computing the visibility map for a polyhedral terrain viewed from a fixed point, and yields an O((n[alpha](n) + k)log n) algorithm."
