The aims of this part are twofold: to provide the beginner with an overview of the terminology and concepts of computer graphics, based on GKS, and to give the computer graphics expert an introduc­ tion to the GKS standard. In the early chapters of this part, the main areas of computer graphics, the various classes of com­ puter graphics users, the interfaces of GKS and its underlying design concepts are discussed and important terms are defined. The later chapters give an informal introduction to the main concepts of GKS and their interrelationships: output, attributes, coordinate systems, transformations, input, segments, metafile, state lists, and error handling. This introduction to the GKS framework will prepare the ground for the detailed description of 2D GKS functions in Part III and the 3D extensions to GKS in Part IV. 1 WHAT IS COMPUTER GRAPHICS? 1. 1 Defmition of Computer Graphics The Data Processing Vocabulary of the International Organization for Stan­ dardization (ISO) [ISO 84] defines Computer Graphics as follows: \"Methods and techniques for converting data to and from a graphic display via computer. \" This definition refers to three basic components of any computer graphics system - namely \"data\", \"computer\", and \"display\".","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52143782265105,"sku":"NLS9783642710810","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783642710810.jpg?v=1789476393"},{"product_id":"user-interface-management-systems-book-gnther-pfaff-9783642700439","title":"User Interface Management Systems","description":"The book contains the proceedings and reports of the Workshop on User Interface Management Systems, held in Seeheim, Federal Re- public of Germany, November 1-3, 1983. The workshop brought toge- ther experts in using and developing techniques for managing the dialo- gue between users and interactive graphics systems. The purpose of the workshop was to produce an agreed report contrasting existing ap- proaches, and outlining directions for future work. Four different areas were defined and addressed at the workshop, namely a) role, model, structure and construction of a UIMS b) dialogue specification tools c) interface of the UIMS to the application d) user's conceptual model All participants prepared papers each in one ofthose problem areas. The papers have been rewritten in the light of the issues discussed during the workshop. Also a subgroup report was produced for each problem area summarizing the results of the discussions at the workshop. Preface User Interface Management Systems (UlMS) are the mediators between the user and the application programs. As more and more in- teractive programs become widely available, methods and techniques of designing and implementing acceptable user interfaces have to be inves- tigated. Since many years, research on the design of user interface mana- gement systems is going on. This EUROGRAPHICS Workshop follows from the ACM SIGRAPH Workshop on Graphical Input and Interac- tion Techniques of May, 1982 in Seattle (see: Computer Graphics 17(1), 1983), and the IFIP WG 5.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52650681041169,"sku":"NLS9783642700439","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783642700439.jpg?v=1786615487"}],"url":"https:\/\/www.worldofbooks.com\/en-gb\/collections\/author-books-by-gnther-pfaff.oembed","provider":"World of Books ","version":"1.0","type":"link"}
