This book was released on 1993 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This paper presents a divide-and-conquer ray-traced volume rendering algorithm and a parallel image compositing method, along with their implementation and performance on the Connection Machine CM-5, and networked workstations. This algoritm distributes both the data and the computations to individual processing units to achieve fast, high- quality rendering of high-resolution data. The volume data, once distributed, is left intact. The processing nodes perform local raytracing of their subvolume concurrently. No communication between processing units is needed during this locally ray-tracing process. A subimage is generated by each processing unit and the final image is obtained by compositing subimages in the proper order, which can be determined a priori. Test results on both the CM-5 and a group of networked workstations demonstrate the practicality of our rendering algorithm and compositing method."

Download or read book Visualization in Scientific Computing 95 written by Riccardo Scateni and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visualization is nowadays indispensable to get insight into the huge amounts of data pro duced by large scale simulations or advanced measurement devices. The use of com puter graphics for scientific purposes has become a well established discipline, known as Scientific Visualization. Many problems still have to be solved, and hence the field is a very active area for research and development. This book represents results of the sixth in a well established series of international workshops on Visualization in Scien tific Computing organized by the EUROGRAPHICS Association in collaboration with CRS4 (Center for Advanced Studies, Research and Development in Sardinia), held from May 3 to May 5,1995, in Chia, Italy. The thirteen contributions selected for this volume cover a wide range of topics, ranging from detailed algorithmic studies to searches for new metaphors. A rough di vision can be made into the parts interaction, irregular meshes, volume rendering, and applications. Interaction in three dimensions is a challenging area for research. The use of three dimensional user interfaces for more natural manipulation of three-dimensional data and their visualization is natural, but is far from trivial to realize. Pang et al. investigate the use of common objects such as spray cans and carving knives as metaphors for visualiza tion tools, in order to provide an intuitive and natural three dimensional user interface. Gibson uses a voxel-based data representation, not only for visualization, but also for physical modeling of objects. A prototype system under development for haptic explo ration is discussed.

This book was released on 2004-05-21 with total page 1446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The natural mission of Computational Science is to tackle all sorts of human problems and to work out intelligent automata aimed at alleviating the b- den of working out suitable tools for solving complex problems. For this reason ComputationalScience,thoughoriginatingfromtheneedtosolvethemostch- lenging problems in science and engineering (computational science is the key player in the ?ght to gain fundamental advances in astronomy, biology, che- stry, environmental science, physics and several other scienti?c and engineering disciplines) is increasingly turning its attention to all ?elds of human activity. In all activities, in fact, intensive computation, information handling, kn- ledge synthesis, the use of ad-hoc devices, etc. increasingly need to be exploited and coordinated regardless of the location of both the users and the (various and heterogeneous) computing platforms. As a result the key to understanding the explosive growth of this discipline lies in two adjectives that more and more appropriately refer to Computational Science and its applications: interoperable and ubiquitous. Numerous examples of ubiquitous and interoperable tools and applicationsaregiveninthepresentfourLNCSvolumescontainingthecontri- tions delivered at the 2004 International Conference on Computational Science and its Applications (ICCSA 2004) held in Assisi, Italy, May 14–17, 2004.

Download or read book Visualization in Supercomputing written by Raul H. Mendez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Massive amounts of numeric data are far more comprehensible when converted into graphical form. Hence visualization is becoming an integral part of many areas of research. The idea of visualization is not new, but techniques for visualization are still being developed, and visualization research is just beginning to be recognized as a cornerstone of future computer science. As scientists handle increasingly complex problems with computers, visualization will become an even more essential tool for extracting sense from numbers. This volume is a collection of the best papers selected from those presented at the August 1988 Visualization in Supercomputing Conference in Tokyo, Japan. It is divided into three parts: visualization applications, hardware and performance, and visualization theory. Subjects covered include visualization methods used in computational fluid dynamics research, time-to-solution aspects of visualization, the use of parallel/vector computers with finite element method systems, basic computational performance of two graphics supercomputers, and the applicability of the volume imaging concept in various fields.
