Author Description

This introductory text recognizes that beginners learn computer graphics more quickly by doing it. Taking a top-down approach, the book gets you started early in writing interesting 3D graphics programs. Each chapter is built around a nontrivial application program. In this programming context, key principles and techniques are explained as needed and in increasing detail. Coverage includes all the topics required for a fundamental understanding of computer graphics, such as light-material interactions, shading, modeling, curves and surfaces, anti-aliasing, texture mapping, and compositing, as well as important hardware issues.To enable this top-down approach, the book first describes an important application programmer's interface, OpenGL, a graphics library available on most platforms, from high-end graphics workstations to PCs. This high-level interface and a basic knowledge of C programming allow you to generate complex interactive applications, even applications involving 3D viewing and event-driven input. OpenGL's well-defined architecture also facilitates the book's technical discussions of algorithm implementations.The Second Edition of this widely used book features enhanced discussion of hierarchy and object orientation, visualization, interaction, and projection; includes additional code examples, such as two new variants of the Sierpinski gasket, display of hierarchical models, shadow generation, and visualization; and covers functionality added to OpenGL 1.1, including vertex arrays.
