Functions and performance of the Basics and Applications of Computer Graphics and Graphic Design
Konya Sanat, Necmettin Erbakan University
This paper focuses on the basics and applications of computer graphics and why it is important for students to be abreast of the nitty-gritty of this area of study and by extension, knowing why the study of computer graphics is of immense importance. Graphic design generally was also touched on the body of this essay. The important areas of this application consist of blueprint and designs, object simulation, general animations and manipulations. Although computer graphics became prominent during the early stages of the advent of computer monitors, there comes also, a number of other output and input gadgets that are essential for computer graphics; these comprise joysticks, mouse, hi-tech color monitors, flash drives and various models of camera and smart phones. For the purpose of clarity, in this write-up, computer graphics and computer designs would be used interchangeably because the process of computer graphics is in the designs system. Also, the design study used in this essa...
Graphical programming and educational technologies
Technology, 2011
The quick evolution in the fields of knowledge, technology and communication has determined us to think more and more often about a strong reform of the "teaching systems". It is taken into considering the usage of the information technologies in education and their correlation to the Open and Distance Learning systems.

A Taxonomy of Program Visualization Systems (p. 11) "Pictorial representations of program structure, control flow, and data have always been part of the programmer's repertoire of tools and techniques. Such representations can simplify and enhance the explanation of specific aspects of a program. Now that workstations are equipped with powerful graphics capabilities, interest has shifted from simple, static representations to dynamic representations of program behavior." (p. 13) "Our definition suggests the model shown in Figure 1 in which program visualization is the result of an interplay of three participants: the programmer who develops the original program, the animator who defines and constructs the mapping, and the viewer who observes the graphical representation. … Our model of visualization as a mapping leads to a classification of systems based on the domain, range, nature, and limitations of the mapping they support. To these four model-inspired criteria we add communication from the animator to the viewer, in other words, using mapping to convey information." (p. 23) "We derived the classification principles of our new taxonomy for program visualization systems from a complete model of program visualization. For formally well-understood areas, the classification is simple and precise. Program visualization systems can readily be differentiated by scope, level of abstraction, specification method, and interface because these criteria have well-defined formal frameworks. … The remaining classification criterion, presentation, is concerned with visual communication. This area has little formal foundation and thus is an ad hoc category in our taxonomy. Because any useful taxonomy must rely on a simple, objective, formal framework, the development of a more formal treatment of visual information presentation is a worthwhile research goal." [Editor's note: Since 1993 the power of visualization graphics has enabled visualization systems to present many more aspects of program behavior, as envisioned in this article.]
Computer Graphics is a branch of Computer Science that deals with graph, image and pictures. The computer is an information processing machine and it is a tool for storing, manipulating and co-relating data. There are many ways to communicate the processed information to the user. The computer graphics is one of the most effective and commonly used way to communicate the processed information to the user. It displays the information in the form of graphics objects such as pictures, charts, graphs and diagrams instead of simple text. Thus we can say that computer graphics makes it is possible to express data in pictorial form. The picture or graphic object may be an engineering drawing, Business graph, architectural structures, a single frame from an animated movie, or a machine parts.
A Basic Computing Course Experience with Multimedia Equipment
This work describes a practical experience in a basic computing discipline, for freshmen in Engineering courses, at FEI, using multimedia equipment, aiming at a major student participation in class. These classes are held in the computing laboratory, and make use of microcomputers and multimedia equipment. Such equipment is normally used not only to present new concepts or resources, but also to describe the programming environment characteristics, and to test programs related to the solution methods adopted: this allows the students to have a greater facility in perception and more time to discuss the mistakes they made in the solution process. The use of this equipment also allows the instructor to gain speed in the course and to enrich his exposition activities. All this contributes to expand the necessary time dedicated both to discussions, involving computational problems, and critical analysis of the solution methods that were adopted by the students. As a result, the students...
A computer-aided teaching package for microprocessor systems education
IEEE Transactions on Education, 1991
This paper describes a computer-aided teaching (CAT) package for use in a microprocessor systems course. It uses the ZSO CPU [ l ] , [5] as the basis for describing how an 8-bit CPU functions internally and as the master of a microcomputer system [2]-[4]. The package, which consists of an assembler and a graphics simulator, aids as a powerful teaching tool that enables the student to learn about the internal architecture of a microprocessor [7]-[lo] as applied to the Z80 CPU and its instruction set with a step by step graphics animation of the instruction execution and timing. The package allows the user to execute a program step by step and to test the operation of the internal registers, buses, and memory contents at every clock edge. This helps the student to understand exactly how the hardware works at the clock cycle, machine cycle, and instruction cycle levels. It also simulates read/write cycles from/ to memory and input-output devices. Finally, it allows the user to write and debug programs at the assembly language or machine code level. The package is menu driven, interactive, flexible, and user-friendly.
This workshop was organized because the authors believe that computer graphics is a key technology in computational science, and so computational science students must get a good grounding in computer graphics in order to contribute fully to the field. In the first of the papers [CUNSH] included in these workshop notes, we discuss the roles of computer graphics packages and computer graphics programming in computational science and argue that students need to develop the understanding of visual communication in the sciences that can only be obtained by developing graphical presentations from first principles. In this paper we also show the link between computer graphics and the modeling and simulation techniques that are important in computational science. In the second of the papers in these notes [CUN02a] we discuss how a beginning computer graphics course can include scientific problem-solving and visual communication, as would be needed in a computer graphics course intended for computational science. Between them, we make the case for a computer graphics course as part of a computational science curriculum.
Proceedings of the 2nd annual conference on Computer graphics and interactive techniques - SIGGRAPH '75, 1975
Stand alone graphic systems and time-shared graphics provide different benefits to a user. The same is true of refresh graphics and storage displays. An operating system is described which supports these combined modes through the integration of graphics into the operating system. Realization of the role of the system, generality, and flexibility were the major factors in the development of the system. The result is a computer graphic system providing high-level interactive graphics at a relatively low cost.
