83-421: Four different compression algorithms are used by FXT1, chosen at a block level to optimize visual quality. Having to select an optimal path for each texture ensured FXT1 was relatively slow at compression, making it unsuitable for real-time compression in applications. The original white paper did not follow well-known scientific rules, being actually a commercial presentation. The lack of theoretical guidance from

166-464: A Return to Castle Wolfenstein movie is in development which re-teams the Silent Hill writer/producer team, Roger Avary as writer and director and Samuel Hadida as producer. A new Doom film, titled Doom: Annihilation , was released in 2019, although id itself stressed its lack of involvement. id Software was the target of controversy over two of their most popular games, Doom and

249-471: A first-person shooter (FPS) with smooth 3D graphics that were unprecedented in computer games, and with violent gameplay that many gamers found engaging. After essentially founding an entire genre with this game, id Software created Doom , Doom II: Hell on Earth , Quake , Quake II , Quake III Arena , Quake 4 , and Doom 3 . Each of these first-person shooters featured progressively higher levels of graphical technology. Wolfenstein 3D spawned

332-618: A "BCPack" compression algorithm specifically for BCn-compressed textures. Xbox series X and S have hardware support for decompressing BCPack streams. Id Software id Software LLC ( / ɪ d / ) is an American video game developer based in Richardson, Texas . It was founded on February 1, 1991, by four members of the computer company Softdisk : programmers John Carmack and John Romero , game designer Tom Hall , and artist Adrian Carmack . id Software made important technological developments in video game technologies for

415-2710: A 4×4 3-bit lookup table) followed by 64 bits of color data (encoded the same way as DXT1). If α 0 > α 1 {\displaystyle \alpha _{0}>\alpha _{1}} , then six other alpha values are calculated, such that α 2 = 6 α 0 + 1 α 1 7 {\textstyle \alpha _{2}={{6\alpha _{0}+1\alpha _{1}} \over 7}} , α 3 = 5 α 0 + 2 α 1 7 {\textstyle \alpha _{3}={{5\alpha _{0}+2\alpha _{1}} \over 7}} , α 4 = 4 α 0 + 3 α 1 7 {\textstyle \alpha _{4}={{4\alpha _{0}+3\alpha _{1}} \over 7}} , α 5 = 3 α 0 + 4 α 1 7 {\textstyle \alpha _{5}={{3\alpha _{0}+4\alpha _{1}} \over 7}} , α 6 = 2 α 0 + 5 α 1 7 {\textstyle \alpha _{6}={{2\alpha _{0}+5\alpha _{1}} \over 7}} , and α 7 = 1 α 0 + 6 α 1 7 {\textstyle \alpha _{7}={{1\alpha _{0}+6\alpha _{1}} \over 7}} . Otherwise, if α 0 ≤ α 1 {\textstyle \alpha _{0}\leq \alpha _{1}} , four other alpha values are calculated such that α 2 = 4 α 0 + 1 α 1 5 {\textstyle \alpha _{2}={{4\alpha _{0}+1\alpha _{1}} \over 5}} , α 3 = 3 α 0 + 2 α 1 5 {\textstyle \alpha _{3}={{3\alpha _{0}+2\alpha _{1}} \over 5}} , α 4 = 2 α 0 + 3 α 1 5 {\textstyle \alpha _{4}={{2\alpha _{0}+3\alpha _{1}} \over 5}} , and α 5 = 1 α 0 + 4 α 1 5 {\textstyle \alpha _{5}={{1\alpha _{0}+4\alpha _{1}} \over 5}} with α 6 = 0 {\displaystyle \alpha _{6}=0} and α 7 = 255 {\displaystyle \alpha _{7}=255} . The lookup table

S3TC is a lossy compression algorithm, resulting in image quality degradation, an effect which is minimized by the ability to increase texture resolutions while maintaining the same memory requirements. Hand-drawn cartoon-like images do not compress well, nor do normal map data, both of which usually generate artifacts . ATI 's 3Dc compression algorithm

581-501: A European ship date of September 15, 2011. During the keynote, id Software also demonstrated a Rage spin-off title running on the iPhone . This technology demo later became Rage HD . The game was ultimately released in October 2011. On May 14, 2018, Bethesda Softworks announced Rage 2 , a co-development between id Software and Avalanche Studios . During its early days, id Software produced much more varied games; these include

664-556: A Linux client available, the only current exceptions being Wolfenstein and Brink . Similarly, almost all of the games utilizing the Quake II engine have Linux ports, the only exceptions being those created by Ion Storm ( Daikatana later received a community port ). Despite fears by the Linux gaming community that id Tech 5 would not be ported to that platform, Timothee Besset in his blog stated "I'll be damned if we don't find

747-405: A cultural phenomenon and its violent theme would eventually launch a new wave of criticism decrying the dangers of violence in video games. Doom was ported to numerous platforms, inspired many knock-offs, and was eventually followed by the technically similar Doom II: Hell on Earth . id Software made its mark in video game history with the shareware release of Doom , and eventually revisited

830-496: A few modifications. Due to the limited features and relatively low sound quality, modern games no longer use IMF music. A large number of songs in id Software's early games (such as Commander Keen and Wolfenstein 3D ) were composed by Bobby Prince in IMF format. Other game developers like Apogee Software also used this format in their games (such as Cosmo's Cosmic Adventure , Duke Nukem II , and Monster Bash ). id Software

913-886: A leading supporter of the Linux platform because we believe it is a technically sound OS and is the OS of choice for many server ops." However, on April 25, 2012, Carmack revealed that "there are no plans for a native Linux client" of id's most recent game, Rage . In February 2013, Carmack argued for improving emulation as the "proper technical direction for gaming on Linux", though this was also due to ZeniMax's refusal to support "unofficial binaries", given all prior ports (except for Quake III Arena , via Loki Software , and earlier versions of Quake Live ) having only ever been unofficial. Carmack didn't mention official games Quake: The Offering and Quake II: Colossus ported by id Software to Linux and published by Macmillan Computer Publishing USA. Despite no longer releasing native binaries, id

996-470: A lowercase id , which is pronounced as in "did" or "kid", and, according to the book Masters of Doom , the group identified itself as "Ideas from the Deep" in the early days of Softdisk but that, in the end, the name 'id' came from the phrase "in demand". Disliking "in demand" as "lame", someone suggested a connection with Sigmund Freud 's psychological concept of id , which the others accepted. Evidence of

While planning for the massacre, Harris said that the killing would be "like playing Doom ", and "it'll be like the LA riots , the Oklahoma bombing , World War II , Vietnam , Duke Nukem and Doom all mixed together", and that his shotgun

1162-426: A prequel and a sequel: the prequel called Spear of Destiny , and the second, Return to Castle Wolfenstein , using the id Tech 3 engine . A third Wolfenstein sequel, simply titled Wolfenstein , was released by Raven Software , using the id Tech 4 engine . Another sequel, named Wolfenstein: The New Order ; was developed by MachineGames using the id Tech 5 engine and released in 2014, with it getting

1245-587: A prequel by the name of Wolfenstein: The Old Blood a year later; followed by a direct sequel titled Wolfenstein II: The New Colossus in 2017. Eighteen months after their release of Wolfenstein 3D , on December 10, 1993, id Software released Doom which would again set new standards for graphic quality and graphic violence in computer gaming. Doom featured a sci-fi / horror setting with graphic quality that had never been seen on personal computers or even video game consoles . Doom became

1328-669: A side-scrolling game that incorporated the previous work they had done on the Super Mario Bros. 3 demonstration. The first Commander Keen game, Commander Keen in Invasion of the Vorticons , was released through Apogee in December 1990, which became a very successful shareware game. After their first royalty check, Romero, Carmack, and Adrian Carmack (no relation) decided to start their own company. After hiring Hall,

In September 1990, Carmack developed an efficient way to rapidly side-scroll graphics on the PC . Upon making this breakthrough, Carmack and Hall stayed up late into the night making a replica of the first level of the popular 1988 NES game Super Mario Bros. 3 , inserting stock graphics of Romero's Dangerous Dave character in lieu of Mario. When Romero saw

1494-411: A value of 3 corresponding to c 3 {\displaystyle c_{3}} . DXT2 and DXT3 (collectively also known as Block Compression 2 or BC2) converts 16 input pixels (corresponding to a 4x4 pixel block) into 128 bits of output, consisting of 64 bits of alpha channel data (4 bits for each pixel) followed by 64 bits of color data, encoded the same way as DXT1 (with the exception that

1577-486: Is a group of related lossy texture compression algorithms originally developed by Iourcha et al. of S3 Graphics, Ltd. for use in their Savage 3D computer graphics accelerator . The method of compression is strikingly similar to the previously published Color Cell Compression , which is in turn an adaptation of Block Truncation Coding published in the late 1970s. Unlike some image compression algorithms (e.g. JPEG ), S3TC's fixed-rate data compression coupled with

1660-487: Is a modification of DXT5 designed to overcome S3TC's shortcomings with regard to normal maps. id Software worked around the normalmap compression issues in Doom 3 by moving the red component into the alpha channel before compression and moving it back during rendering in the pixel shader . Like many modern image compression algorithms, S3TC only specifies the method used to decompress images, allowing implementers to design

1743-515: Is an audio file format created by id Software for the AdLib sound card for use in their video games. The format is similar to MIDI , in that it defines musical notes, and does not support sampled digital audio for sound effects. IMF files store the actual bytes sent to the AdLib's OPL2 chip, which uses FM synthesis to produce audio output. The format is based on the AdLib command syntax, with

1826-454: Is no longer a competitor in the graphics accelerator market, license fees have been levied and collected for the use of S3TC technology until October 2017, for example in game consoles and graphics cards. The wide use of S3TC has led to a de facto requirement for OpenGL drivers to support it, but the patent-encumbered status of S3TC presented a major obstacle to open source implementations, while implementation approaches which tried to avoid

1909-626: Is then consulted to determine the alpha value for each pixel, with a value of 0 corresponding to α 0 {\displaystyle \alpha _{0}} and a value of 7 corresponding to α 7 {\displaystyle \alpha _{7}} . DXT4's color data is premultiplied by alpha, whereas DXT5's is not. Because DXT4/5 use an interpolated alpha scheme, they generally produce superior results for alpha (transparency) gradients than DXT2/3. BC4 and BC5 (Block Compression 4 and 5) are added in Direct3D 10. They reuse

1992-492: Is transparent black corresponding to a premultiplied alpha format . This color sometimes causes a black border surrounding the transparent area when linear texture filtering and alpha test is used, due to colors being interpolated between the color of opaque texel and neighbouring black transparent texel. The lookup table is then consulted to determine the color value for each pixel, with a value of 0 corresponding to c 0 {\displaystyle c_{0}} and

2075-618: The Atari Jaguar version was confiscated following a verdict by the Amtsgericht Berlin Tiergarten on December 7, 1994. The Unterhaltungssoftware Selbstkontrolle lifted the outright ban in 2018 in favor of analysing depictions on a case-by-case basis, and the international version of the game was removed from the list of banned titles in 2019. Due to concerns from Nintendo of America, the Super NES version

2158-452: The Doom series Doom novels . After a brief hiatus from publishing, id resumed and re-launched the novel series in 2008 with Matthew J. Costello 's (a story consultant for Doom 3 and now Rage ) new Doom 3 novels: Worlds on Fire and Maelstrom . id Software became involved in film development when they oversaw the film adaption of their Doom franchise in 2005. In August 2007, Todd Hollenshead stated at QuakeCon 2007 that

2241-585: The Keen engine, but also how it worked internally. id Software has developed their own game engine for each of their titles when moving to the next technological milestone, including Commander Keen , Wolfenstein 3D , ShadowCaster , Doom , Quake , Quake II , and Quake III , as well as the technology used in making Doom 3 . After being used first for id Software's in-house game, the engines are licensed out to other developers. According to Eurogamer.net , "id Software has been synonymous with PC game engines since

2324-470: The PC (running MS-DOS and Windows ), including work done for the Wolfenstein , Doom , and Quake franchises at the time. id's work was particularly important in 3D computer graphics technology and in game engines that are used throughout the video game industry . The company was involved in the creation of the first-person shooter (FPS) genre: Wolfenstein 3D is often considered to be

2407-582: The demo , entitled Dangerous Dave in Copyright Infringement , he realized that Carmack's breakthrough could have potential. The IFD team moonlighted over a week and over two weekends to create a larger demo of their PC version of Super Mario Bros. 3 . They sent their work to Nintendo . According to Romero, Nintendo had told them that the demo was impressive, but "they didn't want their intellectual property on anything but their own hardware, so they told us Good Job and You Can't Do This".

Since id Software revealed their engine id Tech 5 , they call their engines " id Tech ", followed by a version number. Older engines have retroactively been renamed to fit this scheme, with the Doom engine as id Tech 1. IMF ("id music file" or "id's music format")

2739-403: The 3D technology that underlies modern shooter video games. The Quake series continued with Quake II in 1997. Activision purchased a 49% stake in id Software, making it a second party which took publishing duties until 2009. However, the game is not a storyline sequel, and instead focuses on an assault on an alien planet, Stroggos, in retaliation for Strogg attacks on Earth . Most of

2822-813: The 4-color version of the DXT1 algorithm is always used instead of deciding which version to use based on the relative values of c 0 {\displaystyle c_{0}} and c 1 {\displaystyle c_{1}} ). In DXT2, the color data is interpreted as being premultiplied by alpha , in DXT3 it is interpreted as not having been premultiplied by alpha. Typically DXT2/3 are well suited to images with sharp alpha transitions, between translucent and opaque areas. DXT4 and DXT5 (collectively also known as Block Compression 3 or BC3) converts 16 input pixels into 128 bits of output, consisting of 64 bits of alpha channel data (two 8-bit alpha values and

2905-595: The BCn data to the GPU as usual. BCn can be combined with Oodle Texture, a lossy preprocessor that modifies the input texture so that the BCn output is more easily compressed by a LZ77 compressor ( rate-distortion optimization ). BC7 specifically can also use "bc7prep", a lossless pass to re-encode the texture in a more compressible form (requiring its inverse at decompression). crunch is another tool that performs RDO and optionally further re-encoding. In 2021, Microsoft produced

2988-462: The CC_MIXED compression mode, more similar to S3TC , and dropped the other three codecs from the standard. 3dfx was subsequently taken over by Nvidia who have continued to support S3TC as their preferred compression tool. Four different compression algorithms are set out in the original white paper: S3TC S3 Texture Compression ( S3TC ) (sometimes also called DXTn , DXTC , or BCn )

3071-599: The Internet (especially through the add-on QuakeWorld ), seared the title into the minds of gamers as another smash hit. In 2008, id Software was honored at the 59th Annual Technology & Engineering Emmy Awards for the pioneering work Quake represented in user modifiable games. id Software is the only game development company ever honored twice by the National Academy of Television Arts & Sciences , having been given an Emmy Award in 2007 for creation of

3154-679: The PSP, the Nintendo DS and more. Impressive core modifications include GZDoom , which adds to the Doom engine modern hardware accelerared renderers and a scripting system called ZScript, and was also utilized in the creation of ECWolf for Wolfenstein 3D and Raze for the Build engine . Meanwhile DarkPlaces adds stencil shadow volumes into the original Quake engine along with a more efficient network protocol. Other projects include Yamagi Quake II , ioquake3 , and dhewm3 , which maintain

3237-638: The alpha channel encoding found in DXT4/5 (BC3). BC6H (sometimes BC6) and BC7 (Block Compression 6H and 7) are added in Direct3D 11. BC6H and BC7 have a much more complex algorithm with a selection of encoding modes. The quality is much better as a result. These two modes are also specified much more exactly, with ranges of accepted deviation. Earlier BCn modes decode slightly differently among GPU vendors. BCn textures can be further compressed for on-disk storage and distribution ( texture supercompression ). An application would decompress this extra layer and send

3320-1007: The codec itself. DXT1 (also known as Block Compression 1 or BC1) is the smallest variation of S3TC, storing 16 input pixels in 64 bits of output, consisting of two 16-bit RGB 5:6:5 color values c 0 {\displaystyle c_{0}} and c 1 {\displaystyle c_{1}} , and a 4×4 two-bit lookup table. If c 0 > c 1 {\displaystyle c_{0}>c_{1}} (compare these colors by interpreting them as two 16-bit unsigned numbers), then two other colors are calculated, such that for each component, c 2 = 2 3 c 0 + 1 3 c 1 {\textstyle c_{2}={2 \over 3}c_{0}+{1 \over 3}c_{1}} and c 3 = 1 3 c 0 + 2 3 c 1 {\textstyle c_{3}={1 \over 3}c_{0}+{2 \over 3}c_{1}} . This mode operates similarly to mode 0xC0 of

The nVidia GeForce 256 through to GeForce 4 cards also used 16-bit interpolation to render DXT1 textures, which resulted in banding when unpacking textures with color gradients. Again, this created an unfavorable impression of texture compression , not related to the fundamentals of

3486-716: The concept of a detached game engine was first popularized". During the mid to late 1990s, "the launch of each successive round of technology it's been expected to occupy a headlining position", with the Quake III engine being most widely adopted of their engines. However id Tech 4 had far fewer licensees than the Unreal Engine from Epic Games , due to the long development time that went into Doom 3 which id Software had to release before licensing out that engine to others. Despite his enthusiasm for open source code, Carmack revealed in 2011 that he had no interest in licensing

3569-748: The decently popular Dangerous Dave in the Haunted Mansion . In the Haunted Mansion was powered by the same engine as the earlier id Software game Shadow Knights , which was one of the several games written by id Software to fulfill their contractual obligation to produce games for Softdisk , where the id Software founders had been employed. id Software has also overseen several games using its technology that were not made in one of their IPs such as ShadowCaster , (early- id Tech 1 ), Heretic , Hexen: Beyond Heretic (id Tech 1), Hexen II ( Quake engine ), and Orcs and Elves ( Doom RPG engine). id Software has also published novels based on

3652-450: The earlier Wolfenstein 3D . More recently in 2022, id Software found themselves mired in a controversy concerning libel against Doom Eternal's composer. Doom was notorious for its high levels of gore and occultism along with satanic imagery, which generated controversy from a broad range of groups. Yahoo! Games listed it as one of the top ten most controversial games of all time. The game again sparked controversy throughout

3735-535: The early 3D first-person shooter experiments that led to Wolfenstein 3D and Doom – Hovertank 3D and Catacomb 3D . There was also the Rescue Rover series, which had two games – Rescue Rover and Rescue Rover 2 . Also there was John Romero 's Dangerous Dave series, which included such notables as the tech demo ( In Copyright Infringement ) which led to the Commander Keen engine, and

3818-438: The first part of their trilogy as shareware, then sell the other two installments by mail order . Only later (about the time of the release of Doom II ) did id Software release their games via more traditional shrink-wrapped boxes in stores (through other game publishers ). After Wolfenstein 3D ' s great success, id began working on Doom . After Hall left the company, Sandy Petersen and Dave Taylor were hired before

3901-673: The first true FPS; Doom is a game that popularized the genre and PC gaming in general; and Quake was id's first true 3D FPS. On June 24, 2009, ZeniMax Media acquired the company. In 2015, they opened a second studio in Frankfurt , Germany. The founders of id Software – John Carmack , John Romero , and Tom Hall – met in the offices of Softdisk based in Shreveport, Louisiana , developing multiple games for Softdisk's monthly publishing, including Dangerous Dave . Along with another Softdisk employee, Lane Roathe, they had formed

3984-420: The game, or what is more commonly known as the engine. Brainstormed by John Romero , id Software held a weekend session titled "The id Summer Seminar" in the summer of 1991 with prospective buyers including Scott Miller , George Broussard , Ken Rogoway, Jim Norwood and Todd Replogle . One of the nights, id Software put together an impromptu game known as "Wac-Man" to demonstrate not only the technical prowess of

4067-461: The goal of cleaning up the source code, adding features and fixing bugs. Even earlier id Software code, namely for Hovertank 3D and Catacomb 3D , was released in June 2014 by Flat Rock Software . The GPL release of the Quake III engine's source code was moved from the end of 2004 to August 2005 as the engine was still being licensed to commercial customers who would otherwise be concerned over

4150-529: The group finished the Commander Keen series, then hired Jay Wilbur and Kevin Cloud and began working on Wolfenstein 3D . id Software was officially founded by Romero, John and Adrian Carmack and Hall on February 1, 1991. The name "id" came out of their previous IFD; Roathe had left the group, and they opted to drop the "F" to leave "id". They initially used "id" as an initialism for "In Demand", but by

4233-409: The guise of multiple fan letters that Romero came to realize all originated from the same address. When he confronted Miller, Miller explained that the deception was necessary since Softdisk screened letters it received. Although disappointed by not actually having received mail from multiple fans, Romero and other Softdisk developers began proposing ideas to Miller. One of these was Commander Keen ,

In fact, only one-eighth of the shooters showed any special interest in violent video games, far less than the number of shooters who seemed attracted to books and movies with violent content. As for Wolfenstein 3D , due to its use of Nazi symbols such as

Even though the said company has gained more success with its game engine than id Software over the years, Carmack had no regrets by his decision and continued to focus on open source until his departure from the company in 2013. In conjunction with his self-professed affinity for sharing source code , John Carmack has open-sourced most of

4648-571: The major id Software engines under the GNU General Public License . Historically, the source code for each engine has been released once the code base is 5 years old. Consequently, many home grown projects have sprung up porting the code to different platforms, cleaning up the source code, or providing major modifications to the core engine. Wolfenstein 3D , Doom and Quake engine ports are ubiquitous to nearly all platforms capable of running games, such as hand-held PCs, iPods,

4731-524: The new engine called id Tech 5 . Later that year, at QuakeCon 2007, the title of the new game was revealed as Rage . On July 14, 2008, id Software announced at the 2008 E3 event that they would be publishing Rage through Electronic Arts , and not id's longtime publisher Activision . However, since then ZeniMax has also announced that they are publishing Rage through Bethesda Softworks . On August 12, 2010, during Quakecon 2010, id Software announced Rage US ship date of September 13, 2011, and

At least one continuation patent, US6,775,417 , however had a 165-day extension. This continuation patent expired on March 16, 2018. There are five variations of the S3TC algorithm (named DXT1 through DXT5 , referring to the FourCC code assigned by Microsoft to each format), each designed for specific types of image data.
