Graphics Systems

Design and Implementation of 3D Graphics Systems covers the computational aspects of geometric modeling and rendering 3D scenes. Special emphasis is given to the architectural aspects of interactive graphics, geometric modeling, rendering techniques, the graphics pipeline, and the architecture of 3D graphics systems. The text describes basic 3D computer graphics algorithms and their implementation in the C language. The material is complemented by library routines for constructing graphics systems, which are available for download from the book’s website. This book, along with its companion Computer Graphics: Theory and Practice, gives readers a full understanding of the principles and practices of implementing 3D graphics systems.

The 18 research articles of this volume discuss the major themes that have emerged from mathematical and statistical research in the epidemiology of HIV. The opening paper reviews important recent contributions. Five sections follow: Statistical Methodology and Forecasting, Infectivity and the HIV, Heterogeneity and HIV Transmission Dynamics, Social Dynamics and AIDS, and The Immune System and The HIV. In each, leading experts in AIDS epidemiology present the recent results. Some address the role of variable infectivity, heterogeneous mixing, and long periods of infectiousness in the dynamics of HIV; others concentrate on parameter estimation and short-term forecasting. The last section looks at the interaction between the HIV and the immune system.

Professional programmers, engineers, students and researchers concerned with the current state and future development of computer graphics systems should find this publication an essential reference point and a comprehensive implementation guide. The book is characterized by the clarification and concrete determination of separate groups of computer graphics problems, which can be studied and developed relatively independently. The presentation of issues is based on the logic of the graphics systems realization. This logic reflects the work of the designer and the implementor in its movement through the following consecutive steps: design of the graphics system; determining of the graphics system architecture and methods for its realization; realization of the graphics data processing through the development of corresponding algorithms. The primary subject areas considered include: presentation of a model and functionality of 2D and 3D graphics systems; architectures of 2D and 3D graphics systems; possible methods for a graphics system realization; algorithms for graphics data processings; systemized presentation of all problems relevant to the user interface to reflect its influence on the graphics system.

This fourth volume of Advances in Computer Graphics gathers together a selection of the tutorials presented at the EUROGRAPHICS annual conference in Nice, France, Septem ber 1988. The six contributions cover various disciplines in Computer Graphics, giving either an in-depth view of a specific topic or an updated overview of a large area. Chapter 1, Object-oriented Computer Graphics, introduces the concepts of object ori ented programming and shows how they can be applied in different fields of Computer Graphics, such as modelling, animation and user interface design. Finally, it provides an extensive bibliography for those who want to know more about this fast growing subject. Chapter 2, Projective Geometry and Computer Graphics, is a detailed presentation of the mathematics of projective geometry, which serves as the mathematical background for all graphic packages, including GKS, GKS-3D and PRIGS. This useful paper gives in a single document information formerly scattered throughout the literature and can be used as a reference for those who have to implement graphics and CAD systems. Chapter 3, GKS-3D and PHIGS: Theory and Practice, describes both standards for 3D graphics, and shows how each of them is better adapted in different typical applications. It provides answers to those who have to choose a basic 3D graphics library for their developments, or to people who have to define their future policy for graphics.

“Dozens of examples of successful signage at various places—like public spaces, museums, and businesses—around the globe. . . . Each featured work is accompanied by text written by the firm that authored the signage.”—Step Inside Design A signage system is much more than just a set of symbols. As well as its practical application, it helps to create an identity for a space and can add decorative flair to any built environment. Andreas Uebele draws on his own design experience to explore signage as a point where graphic design and architecture come together. He first describes the basic rules of signage design: signs must be visible but not distracting, informative but not unwieldy, and concise but not confusing. Striking the right balance is crucial. Color, typography, pictograms, and icons are all elements that can be varied and exploited to encapsulate as much information as possible and fit the job’s requirements: the signage for a hospital, an airport, or a conference center may have little in common, and solutions must be tailored to fit the location. The book showcases great examples of signage design worldwide, with an emphasis on the most original approaches. It is an indispensable reference for communications designers and a must for architects, interior designers, and graphic artists.
