Computer graphics is a field that deals with creating and manipulating images using computers. It has applications in various domains such as entertainment, education, engineering, medicine, and more. In this article, I will review a book that covers the fundamentals of computer graphics: Computer Graphics by Udit Agarwal.
Computer Graphics is a book that aims to provide a comprehensive introduction to the concepts and techniques of computer graphics. It covers topics such as graphics primitives, images, mathematics for computer graphics, scan conversion, polygons, segments, 2-D and 3-D transformations, windows and clipping, projections, interaction, hidden lines and surfaces, curve generation, rendering and illumination, color models, animation, graphical kernel system, and more. The book also includes numerous examples, exercises, and programming assignments to help the readers practice and apply their knowledge.
The book is written in a clear and concise manner, with a logical flow of topics. The author explains the concepts with diagrams and illustrations to make them easy to understand. The book also provides pseudocode and C programs for some of the algorithms discussed in the book. The book is suitable for undergraduate students of computer science and engineering who want to learn the basics of computer graphics. It can also be used as a reference book by professionals and researchers who work in the field of computer graphics.
Computer Graphics by Udit Agarwal is a book that offers a solid foundation for anyone who wants to learn about computer graphics. It covers the essential topics and techniques of computer graphics in a comprehensive and accessible way. The book is available in paperback format and has 430 pages. It was published by S K Kataria and Sons in 2016[^2^].
One of the strengths of the book is that it covers a wide range of topics in computer graphics, from the basic to the advanced. The book starts with an introduction to computer graphics and its applications, followed by a chapter on graphics primitives and images. The book then introduces the mathematics for computer graphics, such as coordinate systems, vectors, matrices, transformations, and projections. The book also explains how to scan convert and fill various shapes, such as lines, circles, ellipses, polygons, and segments. The book then discusses how to perform 2-D and 3-D transformations on objects, such as translation, rotation, scaling, shearing, reflection, and composite transformations. The book also covers how to clip and window objects in 2-D and 3-D space using different algorithms and techniques.
The book then moves on to more advanced topics in computer graphics, such as hidden lines and surfaces removal, curve generation, rendering and illumination, color models, animation, and graphical kernel system. The book explains how to detect and eliminate hidden lines and surfaces using various methods, such as depth buffer method, z-buffer method, scan-line method, area subdivision method, and painter's algorithm. The book also describes how to generate curves using different techniques, such as interpolation, approximation, parametric curves, Bezier curves, B-spline curves, and NURBS curves. The book also covers how to render and illuminate objects using different models and methods, such as shading models (flat shading, Gouraud shading, Phong shading), illumination models (ambient light, diffuse light, specular light), ray tracing method (reflection, refraction), radiosity method (form factors), and global illumination method (Monte Carlo method). The book also explains how to represent and manipulate colors using different color models (RGB model, CMY model), color spaces (HSV space), color maps (palette), and color quantization (dithering). The book also discusses how to create animations using different techniques (frame-by-frame animation), key-frame animation (tweening), morphing animation (shape interpolation), skeletal animation (inverse kinematics), particle system animation (fireworks), and physics-based animation (collision detection). The book also introduces the graphical kernel system (GKS), which is a standard for computer graphics programming.
The book is well-organized and well-written. The author uses a consistent style and terminology throughout the book. The author also provides clear definitions and explanations of the concepts and terms used in the book. The author also uses diagrams and illustrations to support the text and make it more understandable. The author also provides pseudocode and C programs for some of the algorithms discussed in the book. The author also provides examples, exercises, and programming assignments at the end of each chapter to help the readers practice and apply their knowledge. The book is suitable for undergraduate students of computer science and engineering who want to learn the basics of computer graphics. It can also be used as a reference book by professionals and researchers who work in the field of computer graphics. 0efd9a6b88
