Book excerpt: Abstract: "Phong shading is a very well known shading algorithm for producing realistic images. Real-time Phong shading has on the whole remained too expensive for hardware implementations, either because of excessive computational complexity or because of large storage requirements. The algorithm presented here is designed to produce Phong shaded pixels with the smallest incremental cost using the least storage possible. Its incremental pixel cost is 5 additions with 3 registers to store and accumulate forward differences. This method is well suited to fast hardware implementations but, because of its accuracy and extensibility, it is also an attractive software solution

Download or read book Faster Phong Shading Via Angular Interpolation written by A. A. M. Kuijk and published by . This book was released on 1989 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shading calculation via angular interpolation yields such an ideal algorithm. We will describe two alternative evaluation methods that trade off evaluation cost against level of accuracy. They both can handle light source and view point at arbitrary distances, but differ in level of accuracy. As a consequence these alternative evaluation methods do impose restrictions on the topology of patches and light sources. Generally, the limitations imposed by these alternative shading methods are much more liberal than the limitations on patch size imposed by the geometry. The most economic evaluation method presented can incrementally compute the colour intensity along a scanline by two additions per pixel. The methods presented are generally applicable and can easily be implemented in hardware.

Book excerpt: This volume contains papers representing a comprehensive record of the contributions to the fifth workshop at EG '90 in Lausanne. The Eurographics hardware workshops have now become an established forum for the exchange of information about the latest developments in this field of growing importance. The first workshop took place during EG '86 in Lisbon. All participants considered this to be a very rewarding event to be repeated at future EG conferences. This view was reinforced at the EG '87 Hardware Workshop in Amsterdam and firmly established the need for such a colloquium in this specialist area within the annual EG conference. The third EG Hardware Workshop took place in Nice in 1988 and the fourth in Hamburg at EG '89. The first part of the book is devoted to rendering machines. The papers in this part address techniques for accelerating the rendering of images and efficient ways of improv ing their quality. The second part on ray tracing describes algorithms and architectures for producing photorealistic images, with emphasis on ways of reducing the time for this computationally intensive task. The third part on visualization systems covers a num ber of topics, including voxel-based systems, radiosity, animation and special rendering techniques. The contributions show that there is flourishing activity in the development of new algorithmic and architectural ideas and, in particular, in absorbing the impact of VLSI technology. The increasing diversity of applications encourage new solutions, and graphics hardware has become a research area of high activity and importance.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, a variety of algoritbms are described that may be of interest to everyone who writes software for 3D-graphics. It is a book that haB been written for programmers at an intermediate level as well aB for experienced software engineers who simply want to have some particular functions at their disposal, without having to think too much about details like special cases or optimization for speed. The programming language we use is C, and that has many advantages, because it makes the code both portable and efficient. Nevertheless, it should be possible to adapt the ideas to other high-level programming languages. The reader should have a reasonable knowledge of C, because sophisticated pro grams with economical storage household and fast sections cannot be written without the use of pointers. You will find that in the long run it is just aB easy to work with pointer variables as with multiple arrays . .Aß the title of the book implies, we will not deal with algorithms that are very computation-intensive such as ray tracing or the radiosity method. Furthermore, objects will always be (closed or not closed) polyhedra, which consist of a certain number of polygons.

Download or read book Computer Graphics from Scratch written by Gabriel Gambetta and published by No Starch Press. This book was released on 2021-05-13 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer Graphics from Scratch demystifies the algorithms used in modern graphics software and guides beginners through building photorealistic 3D renders. Computer graphics programming books are often math-heavy and intimidating for newcomers. Not this one. Computer Graphics from Scratch takes a simpler approach by keeping the math to a minimum and focusing on only one aspect of computer graphics, 3D rendering. You’ll build two complete, fully functional renderers: a raytracer, which simulates rays of light as they bounce off objects, and a rasterizer, which converts 3D models into 2D pixels. As you progress you’ll learn how to create realistic reflections and shadows, and how to render a scene from any point of view. Pseudocode examples throughout make it easy to write your renderers in any language, and links to live JavaScript demos of each algorithm invite you to explore further on your own. Learn how to: Use perspective projection to draw 3D objects on a 2D plane Simulate the way rays of light interact with surfaces Add mirror-like reflections and cast shadows to objects Render a scene from any camera position using clipping planes Use flat, Gouraud, and Phong shading to mimic real surface lighting Paint texture details onto basic shapes to create realistic-looking objects Whether you’re an aspiring graphics engineer or a novice programmer curious about how graphics algorithms work, Gabriel Gambetta’s simple, clear explanations will quickly put computer graphics concepts and rendering techniques within your reach. All you need is basic coding knowledge and high school math. Computer Graphics from Scratch will cover the rest.

Download or read book Image Synthesis written by Nadia Magnenat-Thalmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 413 pages. 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.
