characteristics of computer graphics

Sometimes the target of the animation is the computer itself, but sometimes the target is another medium, such as film. When you display a vector graphic on the screen or print it, these formulas are converted into the patterns of dots you can see. "[20] The LINKS-1 was the world's most powerful computer, as of 1984. Early projects like the Whirlwind and SAGE Projects introduced the CRT as a viable display and interaction interface and introduced the light pen as an input device. OpenGL continued to mature as well, and it and DirectX improved greatly; the second-generation shader languages HLSL and GLSL began to be popular in this decade. Experiments into the processing power required to provide graphics in real time at ultra-high-resolution modes like 4K Ultra HD are beginning, though beyond reach of all but the highest-end hardware. DirectX itself remained a commercial success, however.

Another example is that Sutherland's software modeled objects – not just a picture of objects. Such imagery is found in and on television, newspapers, weather reports, and in a variety of medical investigations and surgical procedures. The modern videogame arcade as is known today was birthed in the 1970s, with the first arcade games using real-time 2D sprite graphics. In 1966, the University of Utah recruited Evans to form a computer science program, and computer graphics quickly became his primary interest. Previously, before the advent of computer editing, it was a very time-consuming process, which limited it … The 2D/3D graphics software will change with each keyframe, creating an editable curve of a value mapped over time, in which results in animation. [4], Many tools have been developed to visualize data. Examples are photographs, drawing, graphics designs, maps, engineering drawings, or other images. These curves would form the foundation for much curve-modeling work in the field, as curves – unlike polygons – are mathematically complex entities to draw and model well. At Utah, Sutherland and Evans were highly sought after consultants by large companies, but they were frustrated at the lack of graphics hardware available at the time so they started formulating a plan to start their own company. The Sony PlayStation, Sega Saturn, and Nintendo 64, among other consoles, sold in the millions and popularized 3D graphics for home gamers. CGI became ubiquitous in earnest during this era. The second graphics processor", "LINKS-1 Computer Graphics System-Computer Museum", http://www.vasulka.org/archive/Writings/VideogameImpact.pdf#page=29, "System 16 – Namco System 21 Hardware (Namco)", "System 16 – Taito Air System Hardware (Taito)", Advanced Graphics Programming Techniques Using OpenGL, Computer Graphics: Principles and Practice, Computer Graphics research at UC Berkeley, Thomas Dreher: History of Computer Art, chap. Volume rendering is a technique used to display a 2D projection of a 3D discretely sampled data set. 3D models may be created using multiple approaches: use of NURBs to generate accurate and smooth surface patches, polygonal mesh modeling (manipulation of faceted geometry), or polygonal mesh subdivision (advanced tessellation of polygons, resulting in smooth surfaces similar to NURB models). As the UU computer graphics laboratory was attracting people from all over, John Warnock was another of those early pioneers; he later founded Adobe Systems and create a revolution in the publishing world with his PostScript page description language, and Adobe would go on later to create the industry standard photo editing software in Adobe Photoshop and a prominent movie industry special effects program in Adobe After Effects. SIGGRAPH has grown in size and importance as the field of computer graphics has expanded over time. Speed Race in 1974 featured sprites moving along a vertically scrolling road. A large form of digital art, pixel art is created through the use of raster graphics software, where images are edited on the pixel level. A 3D model can be displayed as a two-dimensional image through a process called 3D rendering, used in a computer simulation of physical phenomena, or animated directly for other purposes. [11][12] MOS LSI technology made possible large amounts of computational capability in small MOS integrated circuit chips, which led to the development of the Tektronix 4010 computer graphics terminal in 1972,[12] as well as the microprocessor in 1971. This cell emitted an electronic pulse whenever it was placed in front of a computer screen and the screen's electron gun fired directly at it. Also sometime in the early 1960s, automobiles would also provide a boost through the early work of Pierre Bézier at Renault, who used Paul de Casteljau's curves – now called Bézier curves after Bézier's work in the field – to develop 3d modeling techniques for Renault car bodies. The 1980s is also called the golden era of videogames; millions-selling systems from Atari, Nintendo and Sega, among other companies, exposed computer graphics for the first time to a new, young, and impressionable audience – as did MS-DOS-based personal computers, Apple IIs, Macs, and Amigas, all of which also allowed users to program their own games if skilled enough. Architecture − Construction plans, exterior sketches - replacing the blueprints and hand drawings of the past. 2D computer graphics are mainly used in applications that were originally developed upon traditional printing and drawing technologies such as typography. In other words, we can say that computer graphics is a rendering tool for the generation and manipulation of images. 2D computer graphics are usually split into two categories: vector graphics and raster graphics. This new department would become the world's primary research center for computer graphics through the 1970s. • • • • Introduction to computer graphics Types of Computer Graphics Difference B/W Active And Passive Graphics Application Of Computer Graphics 32. SPEED : In general, no human being can compete to solving the complex computation, faster than computer. Many scientists and engineers … Their shader languages HLSL and GLSL are active fields of research and development. In order to draw a representation of a 3D object on the screen, the computer must determine which surfaces are "behind" the object from the viewer's perspective, and thus should be "hidden" when the computer creates (or renders) the image. In the field of realistic rendering, Japan's Osaka University developed the LINKS-1 Computer Graphics System, a supercomputer that used up to 257 Zilog Z8001 microprocessors, in 1982, for the purpose of rendering realistic 3D computer graphics. Screens could display art since the Lumiere brothers' use of mattes to create special effects for the earliest films dating from 1895, but such displays were limited and not interactive. Engineering drawings − mechanical, electrical, civil, etc. At the end of each scan line, the electron beam returns to the left side of the screen to begin displaying the next scan line. Rendering is the generation of a 2D image from a 3D model by means of computer programs. AMD also became a leading developer of graphics boards in this decade, creating a "duopoly" in the field which exists this day. 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 character that can be moved on a screen without altering the data defining the overall screen.

Computer graphics is an art of drawing pictures on computer screens with the help of programming. It is also called vector display, stroke-writing display, or calligraphic display. Raster graphics represents images by bitmaps stored in computer memory and displayed on a screen composed of tiny pixels. In the late 1980s, Silicon Graphics (SGI) computers were used to create some of the first fully computer-generated short films at Pixar, and Silicon Graphics machines were considered a high-water mark for the field during the decade. components such as red, green, and blue.
