8892-498: The first shaders – small programs designed specifically to do shading as a separate algorithm – were developed by Pixar , 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, 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

9009-554: The first "immersive" VR experiences. That same year, Carolina Cruz-Neira , Daniel J. Sandin and Thomas A. DeFanti from the Electronic Visualization Laboratory created the first cubic immersive room, the Cave automatic virtual environment (CAVE). Developed as Cruz-Neira's PhD thesis, it involved a multi-projected environment, similar to the holodeck , allowing people to see their own bodies in relation to others in

9126-485: The first artist to produce navigable virtual worlds at NASA 's Jet Propulsion Laboratory (JPL) from 1977 to 1984. The Aspen Movie Map , a crude virtual tour in which users could wander the streets of Aspen in one of the three modes (summer, winter, and polygons ), was created at MIT in 1978. In 1979, Eric Howlett developed the Large Expanse, Extra Perspective (LEEP) optical system. The combined system created

9243-614: The first major commercial release of sensor-based tracking, allowing for free movement of users within a defined space. A patent filed by Sony in 2017 showed they were developing a similar location tracking technology to the Vive for PlayStation VR, with the potential for the development of a wireless headset. In 2019, Oculus released the Oculus Rift S and a standalone headset, the Oculus Quest . These headsets utilized inside-out tracking compared to external outside-in tracking seen in previous generations of headsets. Later in 2019, Valve released

9360-402: The foundation for much curve-modeling work in the field, as curves – unlike polygons – are mathematically complex entities to draw and model well. It was not long before major corporations started taking an interest in computer graphics. TRW , Lockheed-Georgia , General Electric and Sperry Rand are among the many companies that were getting started in computer graphics by the mid-1960s. IBM

9477-565: The history of video games , Spacewar! Written for the DEC PDP-1, Spacewar was an instant success and copies started flowing to other PDP-1 owners and eventually DEC got a copy. The engineers at DEC used it as a diagnostic program on every new PDP-1 before shipping it. The sales force picked up on this quickly enough and when installing new units, would run the "world's first video game" for their new customers. (Higginbotham's Tennis For Two had beaten Spacewar by almost three years, but it

9594-480: The intelligence in the workstation, rather than continuing to rely on central mainframe and minicomputers . 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 Bell-Northern Research , and led by David Pearson, an early workstation pioneer. The Orca 3000

9711-399: The late 1990s and 2000s, 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

9828-423: The later films of the original trilogy. 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 1985, 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 1988,

9945-448: The meaning of "being something in essence or effect, though not actually or in fact" since the mid-1400s. The term "virtual" has been used in the computer sense of "not physically existing but made to appear by software " since 1959. In 1938, French avant-garde playwright Antonin Artaud described the illusory nature of characters and objects in the theatre as "la réalité virtuelle" in

10062-685: The mid-1980s. In 1984, Hitachi released the ARTC HD63484, the first complementary MOS (CMOS) GPU. It was capable of displaying high-resolution in color mode and up to 4K resolution in monochrome mode, and it was used in a number of graphics cards and terminals during the late 1980s. In 1986, TI introduced the TMS34010 , the first fully programmable MOS graphics processor. Computer graphics terminals during this decade became increasingly intelligent, semi-standalone and standalone workstations. Graphics and application processing were increasingly migrated to

10179-572: The millions and popularized 3D graphics for home gamers. Certain late-1990s first-generation 3D titles became seen as influential in popularizing 3D graphics among console users, such as platform games Super Mario 64 and The Legend of Zelda: Ocarina of Time , and early 3D fighting games like Virtua Fighter , Battle Arena Toshinden , and Tekken . Technology and algorithms for rendering continued to improve greatly. In 1996, Krishnamurty and Levoy invented normal mapping – an improvement on Jim Blinn's bump mapping . 1999 saw Nvidia release

10296-439: 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 virtual reality 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

10413-524: The nineties were created, in France, the very first computer graphics TV series: La Vie des bêtes by studio Mac Guff Ligne (1988), Les Fables Géométriques (1989–1991) by studio Fantôme, and Quarxs , the first HDTV computer graphics series by Maurice Benayoun and François Schuiten (studio Z-A production, 1990–1993). In film, Pixar began its serious commercial rise in this era under Edwin Catmull , with its first major film release, in 1995 – Toy Story –

10530-442: 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

10647-431: The room. Antonio Medina, a MIT graduate and NASA scientist, designed a virtual reality system to "drive" Mars rovers from Earth in apparent real time despite the substantial delay of Mars-Earth-Mars signals. In 1992, Nicole Stenger created Angels , the first real-time interactive immersive movie where the interaction was facilitated with a dataglove and high-resolution goggles. That same year, Louis Rosenberg created

10764-507: The seminal GeForce 256 , the first home video card billed as a graphics processing unit or GPU, which in its own words contained "integrated transform , lighting , triangle setup / clipping , and rendering engines". 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

10881-474: 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 computer animation that Catmull saw was his own. He created an animation of his hand opening and closing. He also pioneered texture mapping to paint textures on three-dimensional models in 1974, now considered one of the fundamental techniques in 3D modeling . It became one of his goals to produce

10998-567: The term "VR", was unable to represent virtual reality, and instead displayed 360-degree interactive panoramas . Nintendo 's Virtual Boy console was released in 1995. A group in Seattle created public demonstrations of a "CAVE-like" 270 degree immersive projection room called the Virtual Environment Theater, produced by entrepreneurs Chet Dagit and Bob Jacobson. Forte released the VFX1 ,

11115-411: The term "virtual reality" in the popular media is attributed to Jaron Lanier , who in the late 1980s designed some of the first business-grade virtual reality hardware under his firm VPL Research , and the 1992 film Lawnmower Man , which features use of virtual reality systems. One method of realizing virtual reality is through simulation -based virtual reality. For example, driving simulators give

11232-543: The time, so they started formulating a plan to start their own company. In 1968, Dave Evans and Ivan Sutherland founded the first computer graphics hardware company, Evans & Sutherland . While Sutherland originally wanted the company to be located in Cambridge, Massachusetts, Salt Lake City was instead chosen due to its proximity to the professors' research group at the University of Utah. Also in 1968 Arthur Appel described

11349-521: The underlying sciences of geometry , optics , physics , and perception . 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, such as photo and video content. Computer graphics development has had a significant impact on many types of media and has revolutionized animation , movies , advertising , and video games , in general. The term computer graphics has been used in

11466-475: The user feel as though they are in a virtual world. A common criticism of this form of immersion is that there is no sense of peripheral vision , limiting the user's ability to know what is happening around them. A head-mounted display (HMD) more fully immerses the user in a virtual world. A virtual reality headset typically includes two small high resolution OLED or LCD monitors which provide separate images for each eye for stereoscopic graphics rendering

11583-616: The user the ability to view three-dimensional images. Mixed reality (MR) is the merging of the real world and virtual worlds to produce new environments and visualizations where physical and digital objects co-exist and interact in real time. A cyberspace is sometimes defined as a networked virtual reality. Simulated reality is a hypothetical virtual reality as truly immersive as the actual reality , enabling an advanced lifelike experience or even virtual eternity. The development of perspective in Renaissance European art and

11700-445: The verdict was in favour of ZeniMax, settled out of court later. In 2013, Valve discovered and freely shared the breakthrough of low-persistence displays which make lag-free and smear-free display of VR content possible. This was adopted by Oculus and was used in all their future headsets. In early 2014, Valve showed off their SteamSight prototype, the precursor to both consumer headsets released in 2016. It shared major features with

11817-549: 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. 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. In scientific computing ,

11934-448: 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

12051-418: The world's primary research center for computer graphics through the 1970s. Also, in 1966, Ivan Sutherland continued to innovate at MIT when he invented the first computer-controlled head-mounted display (HMD). It displayed two separate wireframe images, one for each eye. This allowed the viewer to see the computer scene in stereoscopic 3D . The heavy hardware required for supporting the display and tracker

12168-423: Was almost unknown outside of a research or academic setting.) At around the same time (1961–1962) in the University of Cambridge, Elizabeth Waldram wrote code to display radio-astronomy maps on a cathode ray tube. E. E. Zajac, a scientist at Bell Telephone Laboratory (BTL), created a film called "Simulation of a two-giro gravity attitude control system" in 1963. In this computer-generated film, Zajac showed how

12285-513: Was appointed Google's first-ever 'resident artist' in their new VR division. The Kickstarter campaign for Gloveone, a pair of gloves providing motion tracking and haptic feedback, was successfully funded, with over $ 150,000 in contributions. Also in 2015, Razer unveiled its open source project OSVR . By 2016, there were at least 230 companies developing VR-related products. Amazon , Apple, Facebook, Google, Microsoft , Sony and Samsung all had dedicated AR and VR groups. Dynamic binaural audio

12402-484: Was based on the 16-bit Motorola 68000 microprocessor 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 Amiga and Macintosh , as a serious design tool, one that could save time and draw more accurately than other methods. The Macintosh remains

12519-409: Was birthed in the 1970s, with the first arcade games using real-time 2D sprite graphics. Pong in 1972 was one of the first hit arcade cabinet games. Speed Race in 1974 featured sprites moving along a vertically scrolling road. Gun Fight in 1975 featured human-looking animated characters, while Space Invaders in 1978 featured a large number of animated figures on screen; both used

12636-493: Was called the Sword of Damocles because of the potential danger if it were to fall upon the wearer. After receiving his Ph.D. from MIT, Sutherland became Director of Information Processing at ARPA (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 University of Utah – a development which would turn that department into one of

12753-462: Was common to most headsets released that year. However, haptic interfaces were not well developed, and most hardware packages incorporated button-operated handsets for touch-based interactivity. Visually, displays were still of a low-enough resolution and frame rate that images were still identifiable as virtual. In 2016, HTC shipped its first units of the HTC Vive SteamVR headset. This marked

12870-500: Was developed in 1986 – an important step towards implementing global illumination , which is necessary to pursue photorealism in computer graphics. The continuing popularity of Star Wars and other science fiction franchises were relevant in cinematic CGI at this time, as Lucasfilm and Industrial Light & Magic became known as the "go-to" house by many other studios for topnotch computer graphics in film. Important advances in chroma keying ("bluescreening", etc.) were made for

12987-463: 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." The LINKS-1 was the world's most powerful computer , as of 1984. Also in the field of realistic rendering, the general rendering equation of David Immel and James Kajiya

13104-432: 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

13221-532: Was later adapted into the personal computer-based, 3D virtual world program Second Life . The 2000s were a period of relative public and investment indifference to commercially available VR technologies. In 2001, SAS Cube (SAS3) became the first PC-based cubic room, developed by Z-A Production ( Maurice Benayoun , David Nahon), Barco, and Clarté. It was installed in Laval , France. The SAS library gave birth to Virtools VRPack. In 2007, Google introduced Street View ,

13338-636: Was primitive both in terms of user interface and visual realism, and the HMD to be worn by the user was so heavy that it had to be suspended from the ceiling, which gave the device a formidable appearance and inspired its name. Technically, the device was an augmented reality device due to optical passthrough. The graphics comprising the virtual environment were simple wire-frame model rooms. The virtual reality industry mainly provided VR devices for medical, flight simulation, automobile industry design, and military training purposes from 1970 to 1990. David Em became

13455-527: Was quick to respond to this interest by releasing the IBM 2250 graphics terminal, the first commercially available graphics computer. Ralph Baer , a supervising engineer at Sanders Associates , came up with a home video game in 1966 that was later licensed to Magnavox and called the Odyssey . While very simplistic, and requiring fairly inexpensive electronic parts, it allowed the player to move points of light around on

13572-560: Was the first GPU, fabricated on a fully integrated NMOS VLSI chip . It supported up to 1024x1024 resolution , and laid the foundations for the emerging PC graphics market. It was used in a number of graphics cards , and was licensed for clones such as the Intel 82720, the first of Intel's graphics processing units . MOS memory also became cheaper in the early 1980s, enabling the development of affordable framebuffer memory, notably video RAM (VRAM) introduced by Texas Instruments (TI) in

13689-522: Was the first graphical standard to be developed. A group of 25 experts of the ACM Special Interest Group SIGGRAPH 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, Henri Gouraud , Jim Blinn and Bui Tuong Phong contributed to the foundations of shading in CGI via
