INTRODUCTION Computer graphics are pictures and films shaped with the help of computers and usually, the term refers to computer-generated image data twisted with expert graphical hardware and software. It is a immense and lately developed area of computer science and has been introduced in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abridged as CG, though intermittently erroneously referred to as computer-generated imagery (CGI). Some topics in computer graphics comprise of user interface design, sprite graphics, vector graphics, 3D modeling, shaders, GPU design, implicit surface visualization with ray tracing, and computer vision. The by and large methodology depends profoundly on the underlying sciences of geometry, optics, and physics. Computer graphics is answerable for displaying art and image data efficiently and expressively to the consumer. It is also used for processing image data received from the physical world. Computer graphics development has had a noteworthy collision on many types of media and has revolutionized animation, movies, advertising, video games, and graphic design in general. Volume 9 Issue 1 2020 454 http://infokara.com/ INFOKARA RESEARCH ISSN NO: 1021-9056 TYPES OF IMAGE REPRESENTATION IN COMPUTER GRAPHICS 1. Two dimensional type 2D computer graphics are computer-based production of digital images-frequently from models, such as digital image, and by techniques specific to them. These graphics are mainly second-handed in applications that were originally developed upon conventional printing and drawing technologies such as typography. In those applications, the two-dimensional image is not just a illustration of a real-world entity, but an independent artifact with added semantic value; two- dimensional models are therefore favored since these give more direct control of the image than 3D computer graphics, whose approach is more analogous to photography than to typography. Secondly, a huge form of digital art, pixel art is created through the employ of raster graphics software, where images are abridged on the pixel level. Graphics in most old computer and video games, graphing calculator games, and many mobile phone games are by and large pixel art. Thirdly, a sprite is a two-dimensional image or animation that is incorporated into a bigger scene. Initially including just graphical objects handled separately from the memory bitmap of a video display, this now includes various manners of graphical overlays. Originally, sprites were a method of integrating unrelated bitmaps so that they appeared to be part of the normal bitmap on a screen, such as creating an animated temperament that can be enthused on a screen exclusive of altering the data defining the overall screen. Such sprites can be twisted by either electronic circuitry or software. In circuitry, a hardware sprite is a hardware construct that employs custom DMA channels to incorporate visual elements with the core screen in that it super-imposes two discrete video sources. Software can simulate this through specialized rendering methods. Fourthly, the vector graphics formats are harmonizing to raster graphics which is the illustration of images as an array of pixels and is characteristically second-handed for the representation of photographic images. Vector graphics consists in encoding information about shapes and colours that encompass the image, which can tolerate for more elasticity in interpretation. There are instances when working with vector tools and formats is best practice and instances when working with raster tools and formats is most excellent practice and also there are times when both formats come together. An understanding of the advantages and limitations of each technology and the relationship between them is most likely to result in well-organized and successful use of tools. 2. Three-dimensional Type 3D graphics, compared to 2D graphics, are graphics that use a three-dimensional depiction of geometric data. For the rationale of recital, this is stored in the computer. This includes images that may be for later exhibit or for real-time screening. Despite these differences, 3D computer Volume 9 Issue 1 2020 455 http://infokara.com/ INFOKARA RESEARCH ISSN NO: 1021-9056 graphics rely on analogous algorithms as 2D computer graphics do in the structure and raster graphics (like in 2D) in the final rendered display. In computer graphics software, the dissimilarity between 2D and 3D is occasionally blurred; 2D applications may use 3D techniques to accomplish effects such as lighting, and primarily 3D may use 2D rendering techniques. 3D computer graphics are the equivalent as 3D models and are limited within the graphical data file, apart from the rendering. However, there are differences that comprise of the 3D model is the representation of any 3D object. Until visually displayed a model is not graphic. Due to printing, 3D models are not only restrained to virtual space. 3D rendering is how a model can be displayed and also can be used in non-graphical computer simulations and calculations. APPLICATIONS OF COMPUTER GRAPHICS Computer graphics are very constructive in today’s life and approximately every computer can do some graphics, and people have even come to anticipate in controlling their computer through icons and pictures rather than just by typing. Computer-generated imagery is second- handed for movie making, video game and computer program development, scientific modeling, and design for catalogs and other commercial art. We can classify the applications of computer graphics into four main areas: 1. Display of information 2. Design 3. User interfaces 4. Simulation Volume 9 Issue 1 2020 456 http://infokara.com/ INFOKARA RESEARCH ISSN NO: 1021-9056 According to these four areas there are numerous types of applications which are second-handed in today’s world. These include Computational biology, Computational physics, Information graphics, Scientific visualization, Graphic design, Computer-aided design (CAD), Web design, Digital art, Video game, Virtual reality (VR), Computer simulation, and Information visualization. Next, we explain these terms one by one: Computational biology is an interdisciplinary field that applies the techniques of computer science, applied mathematics and statistics to address biological problems. The foremost spotlight lies on developing mathematical modeling and computational simulation techniques. Computational physics is the learning and implementation of numerical algorithm to resolve problems in physics for which a quantitative theory previously exists. It is frequently regarded as a sub discipline of theoretical physics but some consider it transitional branch between theoretical and experimental physics. Information graphics are visual representations of information, data or knowledge and are used where multifaceted information wishes to be explained speedily and clearly, such as in signs, maps, journalism, technical writing, and education. They are also used extensively as tools by computer scientists, mathematicians, and statisticians to simplicity the procedure of developing and communicating conceptual information. Scientific visualization is a subdivision of science, apprehensive with the visualization of three dimensional phenomena, such as architectural, meteorological, medical, and biological Volume 9 Issue 1 2020 457 http://infokara.com/ INFOKARA RESEARCH ISSN NO: 1021-9056 systems. Scientific visualization focuses on the use of computer graphics to create visual images which assist in thoughtful of complex, habitually gigantic numerical depiction of scientific concepts. The term graphic design refers to a number of artistic and professional disciplines which spotlight on visual communication and appearance. Various methods are used to construct and merge symbols, images and words to create a visual representation of thoughts and messages. Graphic design often refers to both the process by which the communication is fashioned and the products which are generated. Computer-aided design (CAD) is the exercise of computer technology for the design of objects, real or virtual. The design of geometric models for object shapes, in particular, is habitually called computer-aided geometric design (CAGD). CAD may be second-handed to design curves and figures in two-dimensional ("2D") space; or curves, surfaces, or solids in three-dimensional ("3D") objects.

  • CHAPTER ONE 1.0 INTRODUCTION 1.1 PROJECT BACKGROUND 1.1.1 Computer Graphics
    CHAPTER ONE 1.0 INTRODUCTION 1.1 PROJECT BACKGROUND Computer graphics and animation is a very broad and wide aspect of computer science, and has effects on our everyday living. Dissemination of information with good graphical user interface becomes very important when very important information have to be passed across. This project would be split into the two aspects (graphics and animation) sometimes during the course of discussion. 1.1.1 Computer Graphics Computers have become a powerful tool for the rapid and economical production of pictures. There is virtually no area in which graphical displays cannot be used to some advantage, and so it is not surprising to find the use of computer graphics so widespread. Although early applications in engineering and science had to rely on expensive and cumbersome equipment, advances in computer technology have made interactive computer graphics a practical tool. Today, we find computer graphics used routinely in such diverse areas as science, Engineering, medicine, business, industry, government, art, entertainment, advertising, Education and training. Before we get into the details of how to do computer graphics, we first take a short tour through a gallery of graphics applications. A major use of computer graphics is in design processes, particularly for engineering and architectural systems, but almost all products are now computer designed. Generally referred to as CAD, computer-aided design methods are now routinely used in the design of buildings, automobiles, aircraft, watercraft, spacecraft, computers, textiles, and many, many other products. For some design applications; object are first displayed in a wireframe outline form that shows the overall sham and internal features of objects.

Agradeço o apoio de todos os que me ajudaram e, em particular, colegas de trabalho e coautores de investigação. ii Resumo A presente dissertação procura traçar uma perspetiva histórica do desenho digital, em particular, nos processos arquitetónicos. O uso do computador e de métodos computacionais no desenho arquitetónico, por meio de programas específicos, tem sido estudado por vários autores no campo da Arquitetura, levando em consideração as mudanças no processo criativo e noutras formas de projetar. Contudo, não tem sido dado relevo à origem dessa mudança, tornando premente resgatar a memória histórica sobre o contexto e os protagonistas dessa transformação que tanto tem marcado a arquitetura do século XXI. Neste sentido, pretende-se evidenciar as origens do desenho digital e olhar para as alterações que o desenho arquitetónico sofreu com a utilização de meios digitais, primeiro nos círculos académicos, nas décadas de sessenta e setenta e depois com uma massificação dos programas CAD (desenho assistido por computador) nas décadas de oitenta e noventa.
