Evans & Sutherland is a pioneering American computer firm in the computer graphics field. Its current products are used in digital projection environments like planetariums. Its simulation business, which it sold to Rockwell Collins, sold products that were used primarily by the military and large industrial firms for training and simulation. ==History== The company was founded in 1968 by David C. Evans and Ivan Sutherland, professors in the Computer Science Department at the University of Utah. The two professors were pioneers in computer graphics technology. They formed the company to produce hardware to run the systems being developed in the University, working from an abandoned barracks on the university grounds. The company was later housed in the University of Utah Research Park. Most of the employees were active or former students, and included Jim Clark, who started Silicon Graphics, Ed Catmull, co-founder of Pixar, and John Warnock of Adobe. In the 1970s they purchased General Electric's flight simulator division and formed a partnership with Rediffusion Simulation, a UK-based flight simulator company, to design and build digital flight simulators. For the next three decades this was E&S's primary market, delivering display systems with enough brightness to light up a simulator cockpit to daytime light levels. These simulators were used for training in in-flight refueling, carrier landing, AWACS, B52 EVS, submarine periscope and space station docking. In the mid 70s until the end of the 80s, E&S produced the ''Picture System'' 1, 2 and PS300 series. These unique "calligraphic" (vector) color displays had depth cueing and could draw large wireframe models and manipulate (rotate, shift, zoom) them in real time. They were mainly used in chemistry to visualize large molecules such as enzymes or polynucleotides. The end of the Picture System line came in the late 80s, when raster devices on workstations could render anti-aliased lines faster. In 1978 the company went public with a listing on NASDAQ. In the 1980s E&S added a Digital Theater division, supplying all-digital projectors to create immersive mass-audience experiences at planetariums, visitor attractions and similar education and entertainment venues. Digital Theater grew to become a major arm of E&S commercial activity with hundreds of Digistar 1 and 2 systems installed around the world, such as at the Saint Louis Science Center in St. Louis, Missouri. For a brief period between 1986 and 1989 E&S was also a supercomputer vendor, but their ES-1 was released just as the supercomputer market was drying up in the post-cold war military wind-down. Only a handful of machines were built, most broken up for scrap. During the 1990s E&S tried to expand into several other commercial markets. The Freedom Series graphics engine was developed to work with Sun Microsystems, IBM, Hewlett Packard, and DEC workstations. 3D Pro technology was developed for the first wave of 3D graphics cards for PCs. Also, the MindSet virtual set system was created to address the needs of the broadcast video market. In 1993 Evans and Sutherland helped Japanese arcade giant Namco with texture-mapping technology in Namco's System 22 arcade board that powered ''Ridge Racer''. The help that E&S gave Namco was similar to the help that Martin Marietta gave Sega with the MODEL 2 board that powered Daytona USA and Desert Tank arcade games. In 1998 Evans and Sutherland acquired AccelGraphics Inc, a manufacturer of computer graphics boards, for $52m. Since its launch in July 2002, the company's Digistar 3 system became the world's fastest selling Digital Theater system and is installed in upwards of 120 fulldome venues worldwide. On May 9, 2006 Evans & Sutherland acquired Spitz Inc, a rival vendor in the planetarium market, giving the combined business the largest base of installed planetaria worldwide and adding in-house projection-dome manufacturing capability to E&S' offering. In 2006 Evans and Sutherland sold its simulation business to Rockwell Collins.〔(【引用サイトリンク】title=E&S - History )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Evans & Sutherland」の詳細全文を読む スポンサード リンク
