Available in PDF, EPUB and Kindle. Book excerpt: LA SYNTHESE D'IMAGE EST UN DOMAINE EN PLEINE EXPANSION ET NECESSITE DES ALGORITHMES CAPABLES DE PRODUIRE RAPIDEMENT DES IMAGES COMPLEXES. NOUS NOUS INTERESSONS A L'ACCELERATION MATERIELLE DU LANCER DE RAYON QUI EST UN ALGORITHME DE SYNTHESE D'IMAGE BASE SUR LE SUIVI DU TRAJET INVERSE DE RAYONS LUMINEUX DANS LA SCENE. CET ALGORITHME PERMET D'OBTENIR DES EFFETS DE LUMIERES COMPLEXES. CEPENDANT, IL NECESSITE DE GRANDS TEMPS DE CALCULS. POUR LES REDUIRE, IL EST NECESSAIRE DE REALISER DES CIRCUITS VLSI DEDIES, SEULS A MEME DE FOURNIR LA PUISSANCE DE CALCUL ADEQUATE. C'EST POURQUOI NOUS MODIFIONS LA MODELISATION DES PRIMITIVES GEOMETRIQUES QUI INTERVIENNENT DANS LE LANCER DE RAYON. ELLES SONT TOUTES MODELISEES DANS L'ESPACE AU-DESSUS, EN GEOMETRIE PROJECTIVE. AINSI, TOUS LES CALCULS SE FONT AVEC UNE DYNAMIQUE FINIE ET NOUS EXERCONS UN CONTROLE FIN DE LEUR PRECISION. TOUS LES CALCULS SE FONT EN VIRGULE FIXE. NOUS SUPPRIMONS EGALEMENT LES DIVISIONS DE LA PLUPART DES CALCULS, CE QUI EST APPRECIABLE POUR LA REALISATION DE CIRCUITS VLSI. UNE FOIS DECRITS QUELQUES OPERATEURS DEDIES DANS DIVERSES PARTIES DE L'ALGORITHME, NOUS ETUDIONS UNE MACHINE PARALLELE HETEROGENE QUI NOUS PERMETTE DE LES UTILISER EFFICACEMENT. LE SYSTEME PROPOSE EST UNE MACHINE PARALLELE A PASSAGE DE MESSAGE QUI EXPLOITE LE PARALLELISME EXPRIME PAR LA DESCRIPTION DE L'ALGORITHME DE LANCER DE RAYON PAR UN ARBRE DE SCENE. CE SYSTEME GERE AUTOMATIQUEMENT LA GESTION DU PARCOURS DE L'ARBRE DE SCENE ET LA SPECIALISATION DES NUDS DE CALCUL. IL NOUS PERMET PLUSIEURS NIVEAUX DE SOUPLESSE MALGRE LA PRESENCE DE CALCULATEURS SPECIALISES. UN OUTIL D'EVALUATION D'ARCHITECTURE DEVELOPPE POUR LA CIRCONSTANCE NOUS PERMET DE FAIRE DES CHOIX COMME LE REGLAGE DES DEBITS, DES PUISSANCES DE CALCUL, DU DEGRE DE SPECIALISATION OU LA TOPOLOGIE DU RESEAU DE PROCESSEURS. LES RESULTATS DES SIMULATIONS OBTENUS NOUS PERMETTENT DE VALIDER NOTRE SYSTEME ET D'ENVISAGER LA REALISATION D'UN PROTOTYPE.

This book was released on 2012-12-06 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Trends in Computer Graphics contains a selection of research papers submitted to Computer Graphics International '88 (COl '88). COl '88 is the Official Annual Conference of the Computer Graphics Society. Since 1982, this conference ha~ been held in Tokyo. This year, it is taking place in Geneva, Switzerland. In 1989, it will be held in Leeds, U. K. , in 1990 in Singapore, in 1991 in U. S. A. and in 1992 in Montreal, Canada. Over 100 papers were submitted to CGI '88 and 61 papers were selected by the International Program Committee. Papers have been grouped into 6 chapters. The flrst chapter is dedicated to Computer Animation because it deals with all topics presented in the other chapters. Several animation systems are described as well as speciflc subjects like 3D character animation, quaternions and splines. The second chapter is dedicated to papers on Image Synthesis, il1 particular new shading models and new algorithms for ray tracing are presented. Chapter 3 presents several algorithms for geometric modeling and new techniques for the creation and manipulation of curves, surfaces and solids and their applications to CAD. In Chapter 4, an important topic is presented: the specification of graphics systems and images using l~nguages and user-interfaces. The last two chapters are devoted to applications in sciences, medicine, engineering, art and business.

Available in PDF, EPUB and Kindle. Book excerpt: Focusing on the computer graphics required to create digital media this book discusses the concepts and provides hundreds of solved examples and unsolved problems for practice. Pseudo codes are included where appropriate but these coding examples do not rely on specific languages. The aim is to get readers to understand the ideas and how concepts and algorithms work, through practicing numeric examples. Topics covered include: 2D Graphics 3D Solid Modelling Mapping Techniques Transformations in 2D and 3D Space Illuminations, Lighting and Shading Ideal as an upper level undergraduate text, Digital Media – A Problem-solving Approach for Computer Graphic, approaches the field at a conceptual level thus no programming experience is required, just a basic knowledge of mathematics and linear algebra.

Download or read book Handbook on Semidefinite Conic and Polynomial Optimization written by Miguel F. Anjos and published by Springer Science & Business Media. This book was released on 2011-11-19 with total page 955 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semidefinite and conic optimization is a major and thriving research area within the optimization community. Although semidefinite optimization has been studied (under different names) since at least the 1940s, its importance grew immensely during the 1990s after polynomial-time interior-point methods for linear optimization were extended to solve semidefinite optimization problems. Since the beginning of the 21st century, not only has research into semidefinite and conic optimization continued unabated, but also a fruitful interaction has developed with algebraic geometry through the close connections between semidefinite matrices and polynomial optimization. This has brought about important new results and led to an even higher level of research activity. This Handbook on Semidefinite, Conic and Polynomial Optimization provides the reader with a snapshot of the state-of-the-art in the growing and mutually enriching areas of semidefinite optimization, conic optimization, and polynomial optimization. It contains a compendium of the recent research activity that has taken place in these thrilling areas, and will appeal to doctoral students, young graduates, and experienced researchers alike. The Handbook’s thirty-one chapters are organized into four parts: Theory, covering significant theoretical developments as well as the interactions between conic optimization and polynomial optimization; Algorithms, documenting the directions of current algorithmic development; Software, providing an overview of the state-of-the-art; Applications, dealing with the application areas where semidefinite and conic optimization has made a significant impact in recent years.
