A 2.45 screenshot, displaying the.Computer graphics are pictures and films created using computers. Usually, the term refers to computer-generated image data created with the help of specialized graphical hardware and software. It is a vast and recently developed area of computer science. The phrase was coined in 1960, by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, though sometimes erroneously referred to as computer-generated imagery (CGI).Some topics in computer graphics include, design, visualization with, and, among others. The overall methodology depends heavily on the underlying sciences of, and.Computer graphics is responsible for displaying art and image data effectively and meaningfully to the consumer. It is also used for processing image data received from the physical world.
Computer graphics development has had a significant impact on many types of media and has revolutionized, and in general. Contents.Overview The term computer graphics has been used in a broad sense to describe 'almost everything on computers that is not text or sound'. Typically, the term computer graphics refers to several different things:. the representation and manipulation of image data by a computer. the various used to create and manipulate images. the sub-field of which studies methods for digitally synthesizing and manipulating visual content, seeToday, computer graphics is widespread. Such imagery is found in and on television, newspapers, weather reports, and in a variety of medical investigations and surgical procedures.
A well-constructed can present complex statistics in a form that is easier to understand and interpret. In the media 'such graphs are used to illustrate papers, reports, theses', and other presentation material.Many tools have been developed to visualize data. Computer generated imagery can be categorized into several different types: two dimensional (2D), three dimensional (3D), and animated graphics.
As technology has improved, have become more common, but are still widely used. Computer graphics has emerged as a sub-field of which studies methods for digitally synthesizing and manipulating visual content. Over the past decade, other specialized fields have been developed like, and more concerned with 'the visualization of phenomena (architectural, meteorological, medical, etc.), where the emphasis is on realistic renderings of volumes, surfaces, illumination sources, and so forth, perhaps with a dynamic (time) component'. See also: Introduction The precursor sciences to the development of modern computer graphics were the advances in, and that took place during the first half of the twentieth century. Screens could display art since the ' use of to create special effects for the earliest films dating from 1895, but such displays were limited and not interactive. The first, the, was invented in 1897 – it in turn would permit the and the military – the more direct precursors of the field, as they provided the first two-dimensional electronic displays that responded to programmatic or user input.
Nevertheless, computer graphics remained relatively unknown as a discipline until the 1950s and the post- period – during which time the discipline emerged from a combination of both pure and academic research into more advanced computers and the 's further development of technologies like, advanced, and developed during the war. New kinds of displays were needed to process the wealth of information resulting from such projects, leading to the development of computer graphics as a discipline.1950s. Sector Control Room.Early projects like the and introduced the as a viable and interaction interface and introduced the as an. Of the Whirlwind SAGE system performed a personal experiment in which a small program he wrote captured the movement of his finger and displayed its vector (his traced name) on a display scope. One of the first interactive video games to feature recognizable, interactive graphics – – was created for an oscilloscope by to entertain visitors in 1958 at and simulated a tennis match. In 1959, innovated again while working at MIT on transforming mathematic statements into computer generated 3D machine tool vectors by taking the opportunity to create a display scope image of a character.Electronics pioneer went public in 1957 after incorporating the decade prior, and established strong ties with through its founders, who were.
This began the decades-long transformation of the southern into the world's leading computer technology hub – now known as. The field of computer graphics developed with the emergence of computer graphics hardware.Further advances in computing led to greater advancements in. In 1959, the computer was developed at. The TX-2 integrated a number of new man-machine interfaces. A could be used to draw sketches on the computer using 's revolutionary. Using a light pen, Sketchpad allowed one to draw simple shapes on the computer screen, save them and even recall them later.
The light pen itself had a small in its tip. This cell emitted an electronic pulse whenever it was placed in front of a computer screen and the screen's fired directly at it. By simply timing the electronic pulse with the current location of the electron gun, it was easy to pinpoint exactly where the pen was on the screen at any given moment. Once that was determined, the computer could then draw a cursor at that location. Sutherland seemed to find the perfect solution for many of the graphics problems he faced.
Even today, many standards of computer graphics interfaces got their start with this early Sketchpad program. One example of this is in drawing constraints.
If one wants to draw a square for example, they do not have to worry about drawing four lines perfectly to form the edges of the box. One can simply specify that they want to draw a box, and then specify the location and size of the box. The software will then construct a perfect box, with the right dimensions and at the right location. Another example is that Sutherland's software modeled objects – not just a picture of objects. In other words, with a model of a car, one could change the size of the tires without affecting the rest of the car. It could stretch the body of car without deforming the tires.1960s.
Arcade versionIt was not long before major corporations started taking an interest in computer graphics., and are among the many companies that were getting started in computer graphics by the mid-1960s. IBM was quick to respond to this interest by releasing the graphics terminal, the first commercially available graphics computer., a supervising engineer at, came up with a home in 1966 that was later licensed to and called the. While very simplistic, and requiring fairly inexpensive electronic parts, it allowed the player to move points of light around on a screen. It was the first consumer computer graphics product. Was director of engineering at 's computer division from 1953 to 1962, after which he worked for the next five years as a visiting professor at Berkeley. There he continued his interest in computers and how they interfaced with people. In 1966, the recruited Evans to form a computer science program, and computer graphics quickly became his primary interest.
This new department would become the world's primary research center for computer graphics.Also in 1966, continued to innovate at MIT when he invented the first computer controlled (HMD). Called the Sword of Damocles because of the hardware required for support, it displayed two separate wireframe images, one for each eye. This allowed the viewer to see the computer scene in. After receiving his Ph.D. From MIT, Sutherland became Director of Information Processing at (Advanced Research Projects Agency), and later became a professor at Harvard. In 1967 Sutherland was recruited by Evans to join the computer science program at the – a development which would turn that department into one of the most important research centers in graphics for nearly a decade thereafter, eventually producing some of the most important pioneers in the field. There Sutherland perfected his HMD; twenty years later, NASA would re-discover his techniques in their research.
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.In 1968, described the first algorithm for what would eventually become known as – a basis point for almost all of modern, as well as the later pursuit of in graphics.In 1969, the initiated A Special Interest Group on Graphics which organizes, and publications within the field of computer graphics. By 1973, the first annual SIGGRAPH conference was held, which has become one of the focuses of the organization. SIGGRAPH has grown in size and importance as the field of computer graphics has expanded over time.1970s. The by and its static renders became emblematic of CGI development during the 1970s.An astonishing number of the breakthroughs in the field in this decade – particularly many important early breakthroughs in the transformation of graphics from utilitarian to realistic – occurred at the in the 1970s, which had hired. Sutherland was paired with to teach an advanced computer graphics class, which contributed a great deal of founding research to the field and taught several students who would grow to found several of the industry's most important companies – namely, and.One of these students was. Catmull had just come from The Boeing Company and had been working on his degree in physics.
Growing up on, Catmull loved animation yet quickly discovered that he did not have the talent for drawing. Now Catmull (along with many others) saw computers as the natural progression of animation and they wanted to be part of the revolution. The first animation that Catmull saw was his own. He created an animation of his hand opening and closing. He also pioneered to paint textures on three-dimensional models in 1974, now considered one of the fundamental techniques in.
It became one of his goals to produce a feature-length motion picture using computer graphics – a goal he would achieve two decades later after his founding role in. In the same class, created an animation of his wife's face.As the UU computer graphics laboratory was attracting people from all over, was another of those early pioneers; he would later found and create a revolution in the publishing world with his page description language, and Adobe would go on later to create the industry standard software in and a prominent movie industry program in. Led the image processing group at UU which worked closely with the computer graphics lab.

Was also there; he would later found.A major advance in 3D computer graphics was created at UU by these early pioneers –. 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. The (or Core) was the first graphical standard to be developed. A group of 25 experts of the developed this 'conceptual framework'.
The specifications were published in 1977, and it became a foundation for many future developments in the field.Also in the 1970s, and contributed to the foundations of in CGI via the development of the and models, allowing graphics to move beyond a 'flat' look to a look more accurately portraying depth. Also innovated further in 1978 by introducing, a technique for simulating uneven surfaces, and the predecessor to many more advanced kinds of mapping used today.The modern as is known today was birthed in the 1970s, with the first arcade games using graphics. In 1972 was one of the first hit arcade cabinet games. In 1974 featured sprites moving along a vertically road. In 1975 featured human-looking sprite character graphics, while in 1978 featured a large number of sprites on screen; both used an and MB14241 to the drawing of sprite graphics.1980s. Was one of many popular that helped to popularize computer graphics to a mass audience in the 1980s.The 1980s began to see the modernization and commercialization of computer graphics. As the proliferated, a subject which had previously been an academics-only discipline was adopted by a much larger audience, and the number of computer graphics developers increased significantly.In the early 1980s, the availability of and microprocessors started to revolutionize high-resolution computer graphics terminals which now increasingly became intelligent, semi-standalone and standalone workstations.
Graphics and application processing were increasingly migrated to the intelligence in the workstation, rather than continuing to rely on central mainframe. Typical of the early move to high-resolution computer graphics intelligent workstations for the computer-aided engineering market were the Orca 1000, 2000 and 3000 workstations, developed by Orcatech of Ottawa, a spin-off from, and led by, an early workstation pioneer. The Orca 3000 was based on Motorola 68000 and AMD bit-slice processors and had Unix as its operating system. It was targeted squarely at the sophisticated end of the design engineering sector. Artists and graphic designers began to see the personal computer, particularly the and, as a serious design tool, one that could save time and draw more accurately than other methods.
The Macintosh remains a highly popular tool for computer graphics among graphic design studios and businesses. Modern computers, dating from the 1980s, often use (GUI) to present data and information with symbols, icons and pictures, rather than text. Graphics are one of the five key elements of technology.In the field of realistic rendering, 's developed the, a that used up to 257, in 1982, for the purpose of rendering realistic. According to the Information Processing Society of Japan: 'The core of 3D image rendering is calculating the luminance of each pixel making up a rendered surface from the given viewpoint, and object position.
The LINKS-1 system was developed to realize an image rendering methodology in which each pixel could be parallel processed independently using. By developing a new software methodology specifically for high-speed image rendering, LINKS-1 was able to rapidly render highly realistic images. It was used to create the world's first 3D -like video of the entire that was made completely with computer graphics. The video was presented at the pavilion at the 1985 International Exposition in.' The LINKS-1 was the world's most powerful, as of 1984.
Also in the field of realistic rendering, the general of David Immel and was developed in 1986 – an important step towards implementing, which is necessary to pursue in computer graphics.The continuing popularity of and other science fiction franchises were relevant in cinematic CGI at this time, as and became known as the 'go-to' house by many other studios for topnotch computer graphics in film. Important advances in ('bluescreening', etc.) were made for the later films of the original trilogy. Two other pieces of video would also outlast the era as historically relevant: ' iconic, near-fully-CGI video for their song ' in 1985, which popularized CGI among music fans of that era, and a scene from the same year featuring the first fully CGI character in a feature movie (an animated stained-glass ). In 1988, the first – small programs designed specifically to do as a separate algorithm – were developed by, which had already spun off from Industrial Light & Magic as a separate entity – though the public would not see the results of such technological progress until the next decade. In the late 1980s, computers were used to create some of the first fully computer-generated at, and Silicon Graphics machines were considered a high-water mark for the field during the decade.The 1980s is also called the of; millions-selling systems from, and, among other companies, exposed computer graphics for the first time to a new, young, and impressionable audience – as did -based personal computers, and, and, which also allowed users to program their own games if skilled enough.
In the, advances were made in commercial, 3D graphics. In 1988, the first dedicated real-time 3D were introduced in arcades, with the and Air System. This innovation would be the precursor of the later home or GPU, a technology where a separate and very powerful chip is used in with a to optimize graphics.1990s. A screenshot from the, built in. And took a great graphical leap forward in the 2000s, becoming able to display graphics in that had previously only been possible pre-rendered and/or on business-level hardware.CGI became ubiquitous in earnest during this era. And CGI had spread the reach of computer graphics to the mainstream by the late 1990s and continued to do so at an accelerated pace in the 2000s. CGI was also adopted en masse for widely in the late 1990s and 2000s, and so became familiar to a massive audience.The continued rise and increasing sophistication of the were crucial to this decade, and 3D rendering capabilities became a standard feature as 3D-graphics GPUs became considered a necessity for makers to offer.
The line of graphics cards dominated the market in the early decade with occasional significant competing presence from. As the decade progressed, even low-end machines usually contained a 3D-capable GPU of some kind as and both introduced low-priced chipsets and continued to dominate the market. Which had been introduced in the 1980s to perform specialized processing on the GPU would by the end of the decade become supported on most consumer hardware, speeding up graphics considerably and allowing for greatly improved and in computer graphics via the widespread adoption of, and a variety of other techniques allowing the simulation of a great amount of detail.Computer graphics used in films and gradually began to be realistic to the point of entering the. Movies proliferated, with traditional animated films like and as well as numerous offerings like dominating the box office in this field. The, released in 2001, was the first fully computer-generated feature film to use photorealistic CGI characters and be fully made with motion capture. The film was not a box-office success, however.
Some commentators have suggested this may be partly because the lead CGI characters had facial features which fell into the 'uncanny valley'. Other animated films like drew attention at this time as well. Also resurfaced with its prequel trilogy and the effects continued to set a bar for CGI in film.In, the and, the line of consoles, and offerings from such as the maintained a large following, as did the. Marquee CGI-heavy titles like the series of, and dozens of others continued to approach, grow the video game industry and impress, until that industry's revenues became comparable to those of movies. Made a decision to expose more easily to the independent developer world with the program, but it was not a success.
DirectX itself remained a commercial success, however. Continued to mature as well, and it and improved greatly; the second-generation shader languages and began to be popular in this decade.In, the technique to pass large amounts of data bidirectionally between a GPU and CPU was invented; speeding up analysis on many kinds of and experiments. The technique has also been used for mining and has applications in.2010s.
A texture rendered close-up using principles – increasingly an active area of research for computer graphics in the 2010s.In the early half of the 2010s, CGI is nearly ubiquitous in video, pre-rendered graphics are nearly scientifically, and real-time graphics on a suitably high-end system may simulate photorealism to the untrained eye.has matured into a multistage process with many layers; generally, it is not uncommon to implement texture mapping, or, lighting maps including and techniques, and into one rendering engine using, which are maturing considerably. Shaders are now very nearly a necessity for advanced work in the field, providing considerable complexity in manipulating, and on a per-element basis, and countless possible effects. Their shader languages and are active fields of research and development. Or PBR, which implements even more maps to simulate real optic light flow, is an active research area as well, along with advanced areas like.
Experiments into the processing power required to provide graphics in at ultra-high-resolution modes like are beginning, though beyond reach of all but the highest-end hardware.In cinema, most are CGI now;, but few, if any, attempt photorealism due to continuing fears of the. Most are 3D.In videogames, the, and currently dominate the home space and are all capable of highly advanced 3D graphics; the is still one of the most active gaming platforms as well.Image types Two-dimensional. (left) and masks (right)are the computer-based generation of —mostly from models, such as digital image, and by techniques specific to them.2D computer graphics are mainly used in applications that were originally developed upon traditional and technologies such as typography.
In those applications, the two-dimensional is not just a representation of a real-world object, but an independent artifact with added semantic value; two-dimensional models are therefore preferred because they give more direct control of the image than, whose approach is more akin to than to.Pixel art. See also:A is a two-dimensional or that is integrated into a larger scene. Initially including just graphical objects handled separately from the memory 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, such as creating an animated character that can be moved on a screen without altering the defining the overall screen. Such sprites can be created by either electronic.
In circuitry, a hardware sprite is a construct that employs custom channels to integrate visual elements with the main screen in that it super-imposes two discrete video sources. Software can simulate this through specialized rendering methods.Vector graphics. Example showing effect of vector graphics versus raster (bitmap) graphics.formats are complementary to.
Raster graphics is the representation of images as an array of and is typically used for the representation of photographic images. Vector graphics consists in encoding information about shapes and colors that comprise the image, which can allow for more flexibility in rendering. There are instances when working with vector tools and formats is best practice, and instances when working with raster tools and formats is best practice. 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 efficient and effective use of tools.Three-dimensional.
See also:3D graphics, compared to 2D graphics, are graphics that use a representation of geometric data. For the purpose of performance, this is stored in the computer. This includes images that may be for later display or for real-time viewing.Despite these differences, 3D computer graphics rely on similar as 2D computer graphics do in the frame and raster graphics (like in 2D) in the final rendered display. In computer graphics software, the distinction between 2D and 3D is occasionally blurred; 2D applications may use 3D techniques to achieve effects such as lighting, and primarily 3D may use 2D rendering techniques.3D computer graphics are the same as 3D models. The model is contained within the graphical data file, apart from the rendering. However, there are differences that include 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 confined to virtual space. 3D rendering is how a model can be displayed. Also can be used in non-graphical and calculations.Computer animation.
An example of.is the art of creating moving images via the use of. It is a subfield of computer graphics.
Increasingly it is created by means of, though are still widely used for stylistic, low bandwidth, and faster needs. Sometimes the target of the animation is the computer itself, but sometimes the target is another, such as. It is also referred to as CGI ( or computer-generated imaging), especially when used in films.Virtual entities may contain and be controlled by assorted attributes, such as transform values (location, orientation, and scale) stored in an object's.
Animation is the change of an attribute over time. Multiple methods of achieving animation exist; the rudimentary form is based on the creation and editing of, each storing a value at a given time, per attribute to be animated. 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.
Other methods of animation include and -based techniques: the former consolidates related elements of animated entities into sets of attributes, useful for creating effects and; the latter allows an evaluated result returned from a user-defined logical expression, coupled with mathematics, to automate animation in a predictable way (convenient for controlling bone behavior beyond what a offers in set up).To create the illusion of movement, an image is displayed on the computer then quickly replaced by a new image that is similar to the previous image, but shifted slightly. This technique is identical to the illusion of movement in and.Concepts and principles Images are typically created by devices such as, etc.Digital images include both images and images, but raster images are more commonly used.Pixel. In the enlarged portion of the image individual pixels are rendered as squares and can be easily seen.In digital imaging, a (or picture element ) is a single point in a.
Pixels are placed on a regular 2-dimensional grid, and are often represented using dots or squares. Each pixel is a of an original image, where more samples typically provide a more accurate representation of the original. The of each pixel is variable; in color systems, each pixel has typically threecomponents such as.are presentations on a surface, such as a computer screen.
Examples are photographs, drawing, graphics designs, or other images. Graphics often combine text and illustration. Graphic design may consist of the deliberate selection, creation, or arrangement of typography alone, as in a brochure, flier, poster, web site, or book without any other element. Clarity or effective communication may be the objective, association with other cultural elements may be sought, or merely, the creation of a distinctive style.Primitives Primitives are basic units which a graphics system may combine to create more complex images or models.The example is Examples would be and in 2d video games, in CAD, or or in 3d rendering. Primitives may be supported in, or the building blocks provided by a.Rendering is the generation of a 2D image from a 3D model by means of computer programs. A scene file contains objects in a strictly defined language or data structure; it would contain geometry, viewpoint, and information as a description of the virtual scene.
The data contained in the scene file is then passed to a rendering program to be processed and output to a or image file. The rendering program is usually built into the computer graphics software, though others are available as plug-ins or entirely separate programs. The term 'rendering' may be by analogy with an 'artist's rendering' of a scene. Although the technical details of rendering methods vary, the general challenges to overcome in producing a 2D image from a 3D representation stored in a scene file are outlined as the along a rendering device, such as a. A GPU is a device able to assist the CPU in calculations. If a scene is to look relatively realistic and predictable under virtual lighting, the rendering software should solve the.
The rendering equation does not account for all lighting phenomena, but is a general lighting model for computer-generated imagery. 'Rendering' is also used to describe the process of calculating effects in a video editing file to produce final video output.3D projection is a method of mapping three dimensional points to a two dimensional plane. As most current methods for displaying graphical data are based on planar two dimensional media, the use of this type of projection is widespread, especially in computer graphics, engineering and drafting. Ray tracing is a technique for generating an by tracing the path of through in an. The technique is capable of producing a very high degree of; usually higher than that of typical methods, but at a greater. Example of shading.
Refers to depth in or illustrations by varying levels of. It is a process used in drawing for depicting levels of darkness on paper by applying media more densely or with a darker shade for darker areas, and less densely or with a lighter shade for lighter areas. There are various techniques of shading including where perpendicular lines of varying closeness are drawn in a grid pattern to shade an area. The closer the lines are together, the darker the area appears. Likewise, the farther apart the lines are, the lighter the area appears. The term has been recently generalized to mean that are applied. Texture mapping is a method for adding detail, surface texture, or colour to a.
Its application to 3D graphics was pioneered by Dr in 1974. A texture map is applied (mapped) to the surface of a shape, or polygon. This process is akin to applying patterned paper to a plain white box. Multitexturing is the use of more than one texture at a time on a polygon.
(created from adjusting parameters of an underlying algorithm that produces an output texture), and (created in an application or imported from a ) are, generally speaking, common methods of implementing texture definition on 3D models in computer graphics software, while intended placement of textures onto a model's surface often requires a technique known as (arbitrary, manual layout of texture coordinates) for, while (NURB) surfaces have their own intrinsic used as texture coordinates. Texture mapping as a discipline also encompasses techniques for creating and that correspond to a texture to simulate height and to help simulate shine and light reflections, as well as to simulate mirror-like reflectivity, also called gloss. Anti-aliasing Rendering resolution-independent entities (such as 3D models) for viewing on a raster (pixel-based) device such as a or inevitably causes mostly along geometric edges and the boundaries of texture details; these artifacts are informally called '. Anti-aliasing methods rectify such problems, resulting in imagery more pleasing to the viewer, but can be somewhat computationally expensive. Various anti-aliasing algorithms (such as ) are able to be employed, then customized for the most efficient rendering performance versus quality of the resultant imagery; a graphics artist should consider this trade-off if anti-aliasing methods are to be used. A pre-anti-aliased being displayed on a screen (or screen location) at a resolution different than the resolution of the texture itself (such as a textured model in the distance from the virtual camera) will exhibit aliasing artifacts, while any will always show aliasing artifacts as they are resolution-independent; techniques such as and help to solve texture-related aliasing problems. Volume rendering.
Volume rendered scan of a forearm with different colour schemes for muscle, fat, bone, and blood.is a technique used to display a of a 3D discretely. A typical 3D data set is a group of 2D slice images acquired by a or scanner.Usually these are acquired in a regular pattern (e.g., one slice every millimeter) and usually have a regular number of image in a regular pattern. This is an example of a regular volumetric grid, with each volume element, or represented by a single value that is obtained by sampling the immediate area surrounding the voxel.3D modeling. Main article:3D modeling is the process of developing a mathematical, representation of any three-dimensional object, called a '3D model', via specialized software. Models may be created automatically or manually; the manual modeling process of preparing geometric data for 3D computer graphics is similar to such as.
3D models may be created using multiple approaches: use of NURBs to generate accurate and smooth surface patches, (manipulation of faceted geometry), or polygonal mesh (advanced tessellation of polygons, resulting in smooth surfaces similar to NURB models). A 3D model can be displayed as a two-dimensional image through a process called, used in a of physical phenomena, or animated directly for other purposes. The model can also be physically created using devices.Pioneers in computer graphics Charles Csuri is a pioneer in computer animation and digital fine art and created the first computer art in 1964. Csuri was recognized by as the father of digital art and computer animation, and as a pioneer of computer animation by the (MoMA). Greenberg is a leading innovator in computer graphics. Greenberg has authored hundreds of articles and served as a teacher and mentor to many prominent computer graphic artists, animators, and researchers such as,. Many of his former students have won Academy Awards for technical achievements and several have won the Achievement Award.
Greenberg was the founding director of the NSF Center for Computer Graphics and Scientific Visualization. Michael Noll was one of the first researchers to use a to create artistic patterns and to formalize the use of random processes in the creation of. He began creating digital art in 1962, making him one of the earliest digital artists. In 1965, Noll along with and were the first to publicly exhibit their computer art.
During April 1965, the Howard Wise Gallery exhibited Noll's computer art along with random-dot patterns. Other pioneers. Main article:The is a sub-field of which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to three-dimensional computer graphics, it also encompasses two-dimensional graphics and.As an discipline, computer graphics studies the manipulation of visual and geometric information using computational techniques. It focuses on the mathematical and computational foundations of image generation and processing rather than purely issues. Computer graphics is often differentiated from the field of, although the two fields have many similarities.Applications Computer graphics may be used in the following areas:.
