Graphics (from Ancient Greek   (graphiks) 'pertaining to drawing, painting, writing, etc.') are visual images or designs on some surface, such as a wall, canvas, screen, paper, or stone, to inform, illustrate, or entertain. In contemporary usage, it includes a pictorial representation of data, as in design and manufacture, in typesetting and the graphic arts, and in educational and recreational software. Images that are generated by a computer are called computer graphics.

Graphics can be functional or artistic. The latter can be a recorded version, such as a photograph, or interpretation by a scientist to highlight essential features, or an artist, in which case the distinction with imaginary graphics may become blurred. It can also be used for architecture.

The earliest graphics known to anthropologists studying prehistoric periods are cave paintings and markings on boulders, bone, ivory, and antlers, which were created during the Upper Palaeolithic period from 40,000 to 10,000 B.C. or earlier. Many of these were found to record astronomical, seasonal, and chronological details. Some of the earliest graphics and drawings are known to the modern world, from almost 6,000 years ago, are that of engraved stone tablets and ceramic cylinder seals, marking the beginning of the historical periods and the keeping of records for accounting and inventory purposes. Records from Egypt predate these and papyrus was used by the Egyptians as a material on which to plan the building of pyramids; they also used slabs of limestone and wood. From 600 to 250 BC, the Greeks played a major role in geometry. They used graphics to represent their mathematical theories such as the Circle Theorem and the Pythagorean theorem.

One difference between photography and other forms of graphics is that a photographer, in principle, just records a single moment in reality, with seemingly no interpretation. However, a photographer can choose the field of view and angle, and may also use other techniques, such as various lenses to choose the view or filters to change the colors. In recent times, digital photography has opened the way to an infinite number of fast, but strong, manipulations. Even in the early days of photography, there was controversy over photographs of enacted scenes that were presented as 'real life' (especially in war photography, where it can be very difficult to record the original events). Shifting the viewer's eyes ever so slightly with simple pinpricks in the negative could have a dramatic effect.

There are two types of computer graphics: raster graphics, where each pixel is separately defined (as in a digital photograph), and vector graphics, where mathematical formulas are used to draw lines and shapes, which are then interpreted at the viewer's end to produce the graphic. Using vectors results in infinitely sharp graphics and often smaller files, but, when complex, like vectors take time to render and may have larger file sizes than a raster equivalent.

In 1950, the first computer-driven display was attached to MIT's Whirlwind I computer to generate simple pictures. This was followed by MIT's TX-0 and TX-2, interactive computing which increased interest in computer graphics during the late 1950s. In 1962, Ivan Sutherland invented Sketchpad, an innovative program that influenced alternative forms of interaction with computers.

In the mid-1960s, large computer graphics research projects were begun at MIT, General Motors, Bell Labs, and Lockheed Corporation. Douglas T. Ross of MIT developed an advanced compiler language for graphics programming. S.A.Coons, also at MIT, and J. C. Ferguson at Boeing, began work in sculptured surfaces. GM developed their DAC-1 system, and other companies, such as Douglas, Lockheed, and McDonnell, also made significant developments. In 1968, ray tracing was first described by Arthur Appel of the IBM Research Center, Yorktown Heights, N.Y.[1]

3D computer graphics began being used in video games in the 1970s with Spasim for the PLATO system in 1974 and FS1 Flight Simulator in 1979. Atari, Inc.'s Battlezone (1980) exposed 3D graphics to a wide audience. Other wireframe and flat-shaded 3D games appeared throughout the 1980s. Ultima Underworld: The Stygian Abyss (1992) was one of the first major video games with texture-mapped polygons.

Computer systems dating from the 1980s and onwards often use a graphical user interface (GUI) to present data and information with symbols, icons, and pictures, rather than text. 3D computer graphics and creation tools became more accessible to video game and film developers in the late 1980s with SGI computers, which were later used to create some of the first fully computer-generated short films at Pixar.

3D graphics became more popular in the 1990s in video games, multimedia, and animation. In 1995, Toy Story, the first full-length computer-generated animation film, was released in cinemas. Since then, computer graphics have become more accurate and detailed, due to more advanced computers and better 3D modeling software applications, such as Maya, 3D Studio Max, and Cinema 4D. Consumer-level 3D graphics acceleration hardware became common in IBM PC compatibles near the end of the decade.

Another use of computer graphics is screensavers, originally intended to prevent the layout of much-used GUIs from 'burning into' the computer screen. They have since evolved into true pieces of art, their practical purpose obsolete; modern screens are not susceptible to such artifacts.

In the 1990s, Internet speeds increased, and Internet browsers capable of viewing images were released, the first being Mosaic. Websites began to use the GIF format to display small graphics, such as banners, advertisements, and navigation buttons, on web pages. Modern web browsers can now display JPEG, PNG and increasingly, SVG images in addition to GIFs on web pages. SVG, and to some extent VML, support in some modern web browsers have made it possible to display vector graphics that are clear at any size. Plugins expand the web browser functions to display animated, interactive and 3-D graphics contained within file formats such as SWF and X3D.

Modern web graphics can be made with software such as Adobe Photoshop, the GIMP, or Corel Paint Shop Pro. Users of Microsoft Windows have MS Paint, which many find to be lacking in features. This is because MS Paint is a drawing package and not a graphics package.

Graphics are visual elements often used to point readers and viewers to particular information. They are also used to supplement text in an effort to aid readers in their understanding of a particular concept or make the concept more clear or interesting. Popular magazines, such as Time, Wired and Newsweek, usually contain graphic material in abundance to attract readers, unlike the majority of scholarly journals. In computing, they are used to create a graphical interface for the user; and graphics are one of the five key elements of multimedia technology. Graphics are among the primary ways of advertising the sale of goods or services.

Graphics are commonly used in business and economics to create financial charts and tables. The term business graphics came into use in the late 1970s, when personal computers became capable of drawing graphs and charts instead of using a tabular format. Business graphics can be used to highlight changes over time.

Advertising is one of the most profitable uses of graphics; artists often do advertising work or take advertising potential into account when creating art, to increase the chances of selling the artwork.Most importantly, graphics give a good look to artwork whenever it is applied. Graphics contribute to the general outlook of a designed artwork, this, in turn, lure interested members of the public to look at the work of art or purchasing it.Any graphical work (especially advertisement) or any work of art that is poorly designed will not persuade the audience. therefore, for an advertisement to persuade and convince readers or viewers, it must be well designed with needed graphical tools so as to bring profit to the designer or advertiser.

The Oxford Illustrated Dictionary uses graphics and technical illustrations to make reading material more interesting and easier to understand. In an encyclopedia, graphics are used to illustrate concepts and show examples of the particular topic being discussed.

Computer graphics are often used in the majority of new feature films, especially those with a large budget. Films that heavily use computer graphics include The Lord of the Rings film trilogy, the Harry Potter films, Spider-Man and War of the Worlds.

.NET Multi-platform App UI (.NET MAUI) provides a cross-platform graphics canvas on which 2D graphics can be drawn using types from the Microsoft.Maui.Graphics namespace. This canvas supports drawing and painting shapes and images, compositing operations, and graphical object transforms.

However, not all elements of the canvas are elements of the graphics state. The graphics state does not include drawing objects, such as paths, and paint objects, such as gradients. Typical elements of the graphics state on each platform include stroke and fill data, and font data.

The ACM SIGGRAPH community is a global nonprofit organization serving the evolution of computer graphics and interactive techniques. With thousands of members across the world, the researchers, artists, developers, filmmakers, scientists, and business professionals of ACM SIGGRAPH are building the future of digital art and interactive design.
