The s began to see the modernization and commercialization of computer graphics. As the home computer 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 s, the availability of bit-slice and bit 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 and mini-computers. Typical of the early move to high-resolution computer graphics intelligent workstations for the computer-aided engineering market were the Orca , and workstations, developed by Orcatech of Ottawa, a spin-off from Bell-Northern Research , and led by David Pearson , an early workstation pioneer. 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 Commodore Amiga and Macintosh , 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 s, often use graphical user interfaces GUI to present data and information with symbols, icons and pictures, rather than text. Graphics are one of the five key elements of multimedia technology. 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, light source , 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 ray tracing.
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 planetarium -like video of the entire heavens that was made completely with computer graphics. The video was presented at the Fujitsu pavilion at the International Exposition in Tsukuba. Important advances in chroma keying "bluescreening", etc. Two other pieces of video would also outlast the era as historically relevant: Dire Straits ' iconic, near-fully-CGI video for their song " Money for Nothing " in , which popularized CGI among music fans of that era, and a scene from Young Sherlock Holmes the same year featuring the first fully CGI character in a feature movie an animated stained-glass knight.
In the late s, 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. The s 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 and Macs , and Amigas , which also allowed users to program their own games if skilled enough.
In the arcades , advances were made in commercial, real-time 3D graphics. In , the first dedicated real-time 3D graphics boards were introduced in arcades, with the Namco System 21  and Taito Air System. The s' overwhelming note was the emergence of 3D modeling on a mass scale and an impressive rise in the quality of CGI generally.
Home computers became able to take on rendering tasks that previously had been limited to workstations costing thousands of dollars; as 3D modelers became available for home systems, the popularity of Silicon Graphics workstations declined and powerful Microsoft Windows and Apple Macintosh machines running Autodesk products like 3D Studio or other home rendering software ascended in importance.
By the end of the decade, the GPU would begin its rise to the prominence it still enjoys today. The field began to see the first rendered graphics that could truly pass as photorealistic to the untrained eye though they could not yet do so with a trained CGI artist and 3D graphics became far more popular in gaming , multimedia , and animation.
In film, Pixar began its serious commercial rise in this era under Edwin Catmull , with its first major film release, in — Toy Story — a critical and commercial success of nine-figure magnitude. The studio to invent the programmable shader would go on to have many animated hits, and its work on prerendered video animation is still considered an industry leader and research trail breaker.

In video games, in , Virtua Racing , running on the Sega Model 1 arcade system board , laid the foundations for fully 3D racing games and popularized real-time 3D polygonal graphics among a wider audience in the video game industry. Back on the PC, Wolfenstein 3D , Doom and Quake , three of the first massively popular 3D first-person shooter games, were released by id Software to critical and popular acclaim during this decade using a rendering engine innovated [ vague ] primarily by John Carmack.

The Sony Playstation , Sega Saturn , and Nintendo 64 , among other consoles, sold in the millions and popularized 3D graphics for home gamers. Technology and algorithms for rendering continued to improve greatly. In , Krishnamurty and Levoy invented normal mapping — an improvement on Jim Blinn's bump mapping. By the end of the decade, computers adopted common frameworks for graphics processing such as DirectX and OpenGL.
Since then, computer graphics have only become more detailed and realistic, due to more powerful graphics hardware and 3D modeling software. AMD also became a leading developer of graphics boards in this decade, creating a "duopoly" in the field which exists this day. CGI became ubiquitous in earnest during this era. Video games and CGI cinema had spread the reach of computer graphics to the mainstream by the late s and continued to do so at an accelerated pace in the s.
CGI was also adopted en masse for television advertisements widely in the late s and s, and so became familiar to a massive audience. The continued rise and increasing sophistication of the graphics processing unit were crucial to this decade, and 3D rendering capabilities became a standard feature as 3D-graphics GPUs became considered a necessity for desktop computer makers to offer. The Nvidia GeForce line of graphics cards dominated the market in the early decade with occasional significant competing presence from ATI. Shaders which had been introduced in the s 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 texture and shading in computer graphics via the widespread adoption of normal mapping , bump mapping , and a variety of other techniques allowing the simulation of a great amount of detail.
Computer graphics used in films and video games gradually began to be realistic to the point of entering the uncanny valley.
CGI movies proliferated, with traditional animated cartoon films like Ice Age and Madagascar as well as numerous Pixar offerings like Finding Nemo dominating the box office in this field. The Final Fantasy: The Spirits Within , released in , was the first fully computer-generated feature film to use photorealistic CGI characters and be fully made with motion capture.
Star Wars also resurfaced with its prequel trilogy and the effects continued to set a bar for CGI in film.

Marquee CGI-heavy titles like the series of Grand Theft Auto , Assassin's Creed , Final Fantasy , BioShock , Kingdom Hearts , Mirror's Edge and dozens of others continued to approach photorealism , grow the video game industry and impress, until that industry's revenues became comparable to those of movies.
Microsoft made a decision to expose DirectX more easily to the independent developer world with the XNA program, but it was not a success.
DirectX itself remained a commercial success, however. In scientific computing , the GPGPU technique to pass large amounts of data bidirectionally between a GPU and CPU was invented; speeding up analysis on many kinds of bioinformatics and molecular biology experiments. The technique has also been used for Bitcoin mining and has applications in computer vision. In the early half of the s, CGI is nearly ubiquitous in video, pre-rendered graphics are nearly scientifically photorealistic , and real-time graphics on a suitably high-end system may simulate photorealism to the untrained eye.
Texture mapping has matured into a multistage process with many layers; generally, it is not uncommon to implement texture mapping, bump mapping or isosurfaces , normal mapping , lighting maps including specular highlights and reflection techniques, and shadow volumes into one rendering engine using shaders , which are maturing considerably. Shaders are now very nearly a necessity for advanced work in the field, providing considerable complexity in manipulating pixels , vertices , and textures on a per-element basis, and countless possible effects. Physically based rendering or PBR, which implements even more maps to simulate real optic light flow, is an active research area as well, along with advanced optics areas like subsurface scattering and photon mapping.
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. In cinema, most animated movies are CGI now; a great many animated CGI films are made per year , but few, if any, attempt photorealism due to continuing fears of the uncanny valley.

Most are 3D cartoons. In videogames, the Microsoft Xbox One , Sony PlayStation 4 , and Nintendo Switch currently dominate the home space and are all capable of highly advanced 3D graphics; the Windows PC is still one of the most active gaming platforms as well. In those applications, the two-dimensional image 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 3D computer graphics , whose approach is more akin to photography than to typography.
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. Graphics in most old or relatively limited computer and video games, graphing calculator games, and many mobile phone games are mostly pixel art. A sprite is a two-dimensional image or animation that is integrated into a larger 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 character that can be moved on a screen without altering the data defining the overall screen. Such sprites can be created by either electronic circuitry or software. In circuitry, a hardware sprite is a hardware construct that employs custom DMA 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 formats are complementary to raster graphics.
