This third edition covers fundamental concepts in creating and manipulating 2D and 3D graphical objects, including topics from classic graphics algorithms to color and shading models. It maintains the style of the two previous editions, teaching each graphics topic in a sequence of concepts, mathematics, algorithms, optimization techniques, and Java coding. Completely revised and updated according to years of classroom teaching, the third edition of this highly popular textbook contains a large number of ready-to-run Java programs and an algorithm animation and demonstration open-source software also in Java. It includes exercises and examples making it ideal for classroom use or self-study, and provides a perfect foundation for programming computer graphics using Java. Undergraduate and graduate students majoring specifically in computer science, computer engineering, electronic engineering, information systems, and related disciplines will use this textbook for theircourses. Professionals and industrial practitioners who wish to learn and explore basic computer graphics techniques will also find this book a valuable resource.

Visual languages have long been lit pursuitofeffective communication 00- tween human and machine. Today, they are suecessfully employed for e:nd~user progmmming, modeliog, rapid prototypmg, and design activities by people ofmany disciplines including arehitects, artists, children,engi~ neers, and scientists. Furthermore. with rapid advances ofthe Internet and Web technology,human~human communication through the Web or eleo- tronie mobile deviees is becoming more and moreprevalent This manuscript provides a comprehensive introduetion to diagmmmatiooI visual programming languages and the technologyofautomatie genemtion ofsnch languages. It covers a broad rangeofcontents from the underlying theoryofgraph grammars to the applications in various domains. Thecon~ tents were ex:l:l:aeted from the papers that my Ph. D. students and I have published in the last 10 years. and are updated and organized in a coherent fashion. The manuseript gives an in. -depth treatmentof all the topic areas. Pointers to related work and further readings are also faeilitated at the end ofeverychapterexeeptChapter 9. Rather than describing how to program visually, the manuscript discusses what are visual programming languages, and how sooh languages and their underlying foundations can be usefully applied to other fields incomputer science that need graphs as the p:rimary meansofrepresentation. Assuming the basic knowledge of computer programming and compiler co:nstruetion, the manuscript can be used as a textbook for senior orgradu~ ate computer science classes on visual languages, or a reference book for programming language classes, practitioners, and researchers inthe related field. The manuscript cannot be completed without the helps of many people.

The book covers elementary concepts, from how to produce simple graphical objects using logical coordinates to producing filled regions. The book reinforces concepts with useful and simple examples, then progresses to applied geometry (vectors, polygons) and then onto how to perform rotations and other transformations of graphical objects. In a logical progression of ideas, the reader is introduced to some of the classic graphics algorithms and finally to chapters which cover particular effects such as perspective drawings and hidden-face and hidden-line elimination. The book also provides a host of ready-to-run programs and worked examples to illuminate general principles and geometric techniques for the creation of both 2D and 3D graphical objects.
