Editing Perlin noise (section)

==History ==

[[Ken Perlin]] developed Perlin noise in 1983 as a result of his frustration with the "machine-like" look of [[computer-generated imagery]] (CGI) at the time.<ref name="ken_powerpoint">{{cite web| url= http://www.noisemachine.com/talk1/| title= Making Noise| first= Ken| last= Perlin | archiveurl= https://web.archive.org/web/20071008162042/http://www.noisemachine.com/talk1/| url-status= dead | archive-date= October 8, 2007| website= noisemachine.com| publisher= Ken Perlin}}</ref> He formally described his findings in a [[SIGGRAPH]] paper in 1985 called "An Image Synthesizer".<ref name="Perlin:1985:IS:325165.325247">{{cite journal|last1=Perlin|first1=Ken|title=An image synthesizer |journal=ACM SIGGRAPH Computer Graphics |date=July 1985 |volume= 19| issue= 97–8930 |pages= 287–296|doi=10.1145/325165.325247| ref=perlin_noise_siggraph_paper}}</ref> He developed it after working on [[Disney]]'s [[computer animated]] [[sci-fi]] motion picture ''[[Tron]]'' (1982) for the animation company [[Mathematical Applications Group]] (MAGI).<ref>{{Cite web |last=Perlin |first=Ken |title=In the beginning: The Pixel Stream Editor |url=https://www.csee.umbc.edu/~olano/s2002c36/ch04.pdf |access-date=May 31, 2022}}</ref> In 1997, Perlin was awarded an [[Academy Award for Technical Achievement]] for creating the algorithm, the citation for which read:<ref>{{Cite magazine |last=Tanner |first=Mike |title=Oscar is FX Wizard's Reward |language=en-US |magazine=Wired |url=https://www.wired.com/1997/01/oscar-is-fx-wizards-reward/ |access-date=2022-05-31 |issn=1059-1028}}</ref><ref name="kens_aa">[http://mrl.nyu.edu/~perlin/doc/oscar.html#noise Original source code]</ref><ref>{{Cite web |url=http://mrl.nyu.edu/~perlin/doc/oscar.html |title=Ken's Academy Award |access-date=2011-05-29 |archive-date=2018-05-01 |archive-url=https://web.archive.org/web/20180501200154/http://mrl.nyu.edu/~perlin/doc/oscar.html |url-status=bot: unknown }} of Ken Perlin's 'coherent noise function'</ref><ref name="gustavson">{{cite web |last1=Gustavson |first1=Stefan |title=Simplex noise demystified |url=http://staffwww.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf |accessdate=24 April 2019 |archive-date=21 March 2023 |archive-url=https://web.archive.org/web/20230321011148/http://staffwww.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf |url-status=dead }}</ref>
{{quote|To Ken Perlin for the development of Perlin Noise, a technique used to produce natural appearing [[texture mapping|texture]]s on computer generated surfaces for motion picture visual effects.
The development of Perlin Noise has allowed computer graphics artists to better represent the complexity of natural phenomena in visual effects for the motion picture industry.}}

Perlin did not apply for any patents on the algorithm, but in 2001 he was granted a patent for the use of 3D+ implementations of [[simplex noise]] for [[texture synthesis]]. Simplex noise has the same purpose, but uses a simpler space-filling grid. Simplex noise alleviates some of the problems with Perlin's "classic noise", among them computational complexity and visually-significant directional artifacts.<ref>{{cite patent |country=US |number=6867776 |status=patent |title=Standard for perlin noise |pubdate= |gdate=2005-03-15 |fdate=2001-01-10 |pridate=2001-01-10 |inventor= Kenneth Perlin |assign1=Kenneth Perlin  |assign2=Wsou Investments LLC}}</ref>
