Available in PDF, EPUB and Kindle. Book excerpt: The goal of image synthesis is to create, using the computer, a visual experience that is identical to what a viewer would experience when viewing a real environment. Radiosity and Realistic Image Synthesis offers the first comprehensive look at the radiosity method for image synthesis and the tools required to approach this elusive goal. Basic concepts and mathematical fundamentals underlying image synthesis and radiosity algorithms are covered thoroughly. (A basic knowledge of undergraduate calculus is assumed). The algorithms that have been developed to implement the radiosity method ranging from environment subdivision to final display are discussed. Successes and difficulties in implementing and using these algorithms are highlighted. Extensions to the basic radiosity method to include glossy surfaces, fog or smoke, and realistic light sources are also described. There are 16 pages of full colour images and over 100 illustrations to explain the development and show the results of the radiosity method. Results of applications of this new technology from a variety of fields are also included. Michael Cohen has worked in the area of realistic image synthesis since 1983 and was instrumental in the development of the radiosity method. He is currently an assistant professor of computer science at Princeton University. John Wallace is a software engineer at 3D/EYE, Inc., where he is the project leader for the development of Hewlett-Packard's ATRCore radiosity and ray tracing library. A chapter on the basic concepts of image synthesis is contributed by Patrick Hanrahan. He has worked on the topic of image synthesis at Pixar, where he was instrumental in the development of the Renderman software. He has also led research on the hierarchical methods at Princeton University, where he is an associate professor of computer science. All three authors have written numerous articles on radiosity that have appeared in the SIGGAPH proceedings and elsewhere. They have also taught the SIGGRAPH course on radiosity for 5 years. * The first comprehensive book written about radiosity - Features applications from the fields of computer graphics, architecture, industrial design, and related computer aided design technologies - Offers over 100 illustrations and 16 pages of full-color images demonstrating the results of radiosity methods - Contains a chapter authored by Pat Hanrahan on the basic concepts of image synthesis and a foreword by Donald Greenberg

Available in PDF, EPUB and Kindle. Book excerpt: Image Synthesis: Theory and Practice is the first book completely dedicated to the numerous techniques of image synthesis. Both theoretical and practical aspects are treated in detail. Numerous impressive computer-generated images are used to explain the most advanced techniques in image synthesis. The book contains a detailed description of the most fundamental algorithms; other less important algorithms are summarized or simply listed. This volume is also a unique handbook of mathematical formulae for image synthesis. The four first chapters of the book survey the basic techniques of computer graphics which play an important role in the design of an image: geometric models, image and viewing transformations, curves and surfaces and solid modeling techniques. In the next chapters, each major topic in image synthesis is presented. The first important problem is the detection and processing of visible surfaces, then two chapters are dedicated to the central problem of light and illumination. As aliasing is a major problem in image rendering, the fundamental antialiasing and motion blur techniques are explained. The most common shadow algorithms are then presented as well as techniques for producing soft shadows and penumbrae. In the last few years, image rendering has been strongly influenced by ray tracing techniques. For this reason, two chapters are dedicated to this important approach. Then a chapter is completely dedicated to fractals from the formal Mandelbrot theory to the recursive subdivision approaches. Natural phenomena present a particularly difficult challenge in image synthesis. For this reason, a large portion of the book is devoted to latest methods to simulate these phenomena: particle systems, scalar fields, volume density scattering models. Various techniques are also described for representing terrains, mountains, water, waves, sky, clouds, fog, fire, trees, and grass. Several techniques for combining images are also explained: adaptive rendering, montage and composite methods. The last chapter presents in detail the MIRALab image synthesis software.
Download or read book Image Synthesis written by Gérard Hégron and published by MIT Press (MA). This book was released on 1988 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Image Synthesisbrings together all the basic techniques needed for the production of computer images. Specifically designed to be a practical tool for the user of computer graphics systems, it provides a library of correct algorithms and offers an original set of methodological procedures that will enable a user to solve problems from the particular to the most general level. The book examines the three major classes of image synthesis - curve generation, zone filling, and geometric processing - providing the fundamentals for any image synthesis system. It presents a systematic review of the algorithms needed for each class of problem, highlighting the advantages and disadvantages of each; the algorithms have been written in a descriptive language, allowing the user to program them in whatever language he or she desires. Despite the wide variety of algorithms presented, Hegron draws them together into two unifying procedures, which he discusses in great detail: curve generation based on Bresenham's methods, and contour following. Because these two techniques can be applied to such a diversity of problems, they provide the user with a systematic basis for a software package. Gerard Hegron is a research scientist in the National Institut of Research in Computer Science and Automatic Control (INRIA, France).
Download or read book Visibility Algorithms in the Plane written by Subir Kumar Ghosh and published by Cambridge University Press. This book was released on 2007-03-29 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: A human observer can effortlessly identify visible portions of geometric objects present in the environment. However, computations of visible portions of objects from a viewpoint involving thousands of objects is a time consuming task even for high speed computers. To solve such visibility problems, efficient algorithms have been designed. This book presents some of these visibility algorithms in two dimensions. Specifically, basic algorithms for point visibility, weak visibility, shortest paths, visibility graphs, link paths and visibility queries are all discussed. Several geometric properties are also established through lemmas and theorems. With over 300 figures and hundreds of exercises, this book is ideal for graduate students and researchers in the field of computational geometry. It will also be useful as a reference for researchers working in algorithms, robotics, computer graphics and geometric graph theory, and some algorithms from the book can be used in a first course in computational geometry.
Download or read book Image Synthesis written by Michel Bret and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The images produced by means ofcomputers have invaded our daily lives. One has but to see the "identification logos" of most television broadcasts or some advenisement "spots" to be convinced of this. This proves that the synthesis ofimages has reached maturity. The progress that has been made in the last few years allows one to predict the use ofrealistic illustrations in more and more domains ofapplication. It is thus understandable that more and more people seek to understand how these images are produced. Such a person may be an amateur who likes to understand in a general way the processing involved, or he may be a computer scientist who wants to develop some new application using graphics procedures. This book by Michel Bret meets these desires by giving a complete overview of the techniques of image synthesis by computer. The different stages of the creation of a numerical image are explained in detail, and they are accompanied by descriptions of the most modem methods. Thus the geometrical models that are described go from those with plane polygonal facets, via surfaces of all types, to systems of panicles. Visualization is treated in complete detail, and due attention is given to all the various roads that lead to a realistic image: simple projections on the basis of wire-frame models, the elimination of hidden pans, and fmally the modelling oflight and its effects.
Download or read book Principles of Digital Image Synthesis written by Andrew S. Glassner and published by Elsevier. This book was released on 2014-06-28 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: Image synthesis, or rendering, is a field of transformation: it changes geometry and physics into meaningful images. Because the most popular algorithms frequently change, it is increasingly important for researchers and implementors to have a basic understanding of the principles of image synthesis. Focusing on theory, Andrew Glassner provides a comprehensive explanation of the three core fields of study that come together to form digital image synthesis: the human visual system, digital signal processing, and the interaction of matter and light. Assuming no more than a basic background in calculus, Glassner transforms his passion and expertise into a thorough presentation of each of these disciplines, and their elegant orchestration into modern rendering techniques such as radiosity and ray tracing.
Download or read book View Synthesis Using Stereo Vision written by Daniel Scharstein and published by Springer. This book was released on 2003-06-29 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Image-based rendering, as an area of overlap between computer graphics and computer vision, uses computer vision techniques to aid in sythesizing new views of scenes. Image-based rendering methods are having a substantial impact on the field of computer graphics, and also play an important role in the related field of multimedia systems, for applications such as teleconferencing, remote instruction and surgery, virtual reality and entertainment. The book develops a novel way of formalizing the view synthesis problem under the full perspective model, yielding a clean, linear warping equation. It shows new techniques for dealing with visibility issues such as partial occlusion and "holes". Furthermore, the author thoroughly re-evaluates the requirements that view synthesis places on stereo algorithms and introduces two novel stereo algorithms specifically tailored to the application of view synthesis.

Book excerpt: This thesis addresses the from-polygon visibility problem in an applicative context. First of all, we underline the void which exists between the theory which allows an elegant description of this problem and the practice which struggles to provide efficient implementations. Then, we build on the theoretical concept of equivalence classes of oriented lines in order to propose two new algorithms which analytically encode from-polygon occlusion and from-polygon visibility in Plücker space. Both algorithms use this information to take advantage of the visual coherence which exists between neighbor points on the same polygon and speed up individual from-point queries. Contrary to previous methods, our approach is very robust, and the information is encoded lazily at run time, as directed by the visibility queries. The two applicative contexts are the generation of soft shadows and the calculation of ambient occlusion in image synthesis. Our from-polygon occlusion algorithmdistinguishes between occluded and unoccluded lines and it is used to calculate the exact fragments of a light source which are visible from the points to shade. Our from-polygon visibility algorithm improves this definition and analytically groups the view rays issued from a surface according to the first geometry they intersect. Both our algorithms achieve high quality results that are not sensitive to noise or other visual imperfections, contrary to other methods based on either sampling or visibility approximations. Moreover, our algorithms are competitive with respect to a standard production solution.
