172-592: 3dfx Interactive, Inc. was an American computer hardware company headquartered in San Jose, California , founded in 1994, that specialized in the manufacturing of 3D graphics processing units , and later, video cards . It was a pioneer in the field from the late 1990s to 2000. The company's original product was the Voodoo Graphics, an add-in card that implemented hardware acceleration of 3D graphics. The hardware accelerated only 3D rendering, relying on
344-457: A DAC , a frame buffer processor and a texture mapping unit , along with 4 MB of EDO DRAM . The RAM and graphics processors operated at 50 MHz . It provided only 3D acceleration and as such the computer also needed a traditional video controller for conventional 2D software. A pass-through VGA cable daisy-chained the video controller to the Voodoo, which was itself connected to
516-400: A "paradigm shift", prompting the rise in popularity of 3D games, first-person shooters, licensed technology between developers, and support for game modifications. It helped spark the rise of both online multiplayer games and player-driven content generation, and popularized the business model of online distribution. In their book Dungeons & Dreamers: A Story of how Computer Games Created
688-657: A 1997 version of Quake that used the OpenGL API. The MiniGL translated OpenGL commands into Glide, and gave 3dfx the advantage as the sole consumer chip company to deliver a functional graphics library driver until 1998. Towards the end of 1995, the cost of DRAM dropped significantly and 3dfx was able to enter the consumer PC hardware market with aggressive pricing compared to the few previous 3D graphics solutions for computers. Prior to affordable 3D hardware, games such as Doom and Quake had compelled video game players to move from their 80386s to 80486s , and then to

Unlike the internal bus, the external bus is connected using a bus controller that allows the peripheral system to operate at a different speed from the CPU. Input and output devices are used to receive data from
1032-403: A Global Community in 2014, Brad King and John Borland claimed that Doom was one of the first widespread instances of an "online collective virtual reality", and did more than any other game to create a modern world of "networked games and gamers". PC Gamer proclaimed Doom the most influential game of all time in 2004, and in 2023 said its development was one of the most well-documented in
1204-400: A cohesive gameplay experience. The team also added a third programmer, Dave Taylor . Petersen and Romero designed the rest of Doom 's levels, with different aims: the team believed that Petersen's designs were more technically interesting and varied, while Romero's were more aesthetically interesting. In late 1993, a month before release, John Carmack began to add multiplayer. After
1376-590: A commensurate increase in energy use and cooling demand. The personal computer is one of the most common types of computer due to its versatility and relatively low price. Virtual hardware is software that mimics the function of hardware; it is commonly used in infrastructure as a Service (IaaS) and platform as a Service (PaaS). Embedded systems have the most variation in their processing power and cost: from an 8-bit processor that could cost less than USD $ 0.10, to higher-end processors capable of billions of operations per second and costing over USD$ 100. Cost
1548-664: A community that has persisted for decades since. The deathmatch mode was an important factor in its popularity. Doom was the first game to coin the term "deathmatch" and introduced multiplayer shooting battles to a wide audience. This led to a widespread community of players who had never experienced fast-paced multiplayer combat before. Another popular aspect of Doom was the versatility of its WAD files, enabling user-generated levels and other game modifications. John Carmack and Romero had strongly advocated for mod support, overriding other id employees who were concerned about commercial and legal implications. Although WAD files exposed

Despite the separation of the computing unit and the I/O system in many diagrams, typically the hardware is shared, with a bit in the computing unit indicating whether it is in computation or I/O mode. Common types of ISAs include CISC ( complex instruction set computer ), RISC ( reduced instruction set computer ), vector operations , and hybrid modes. CISC involves using

The level and graphical data was stored in WAD files, short for "Where's All the Data?", separately from the engine. This allowed for any part of the design to be changed without needing to adjust the engine code. Carmack designed this system so that fans could easily modify the game; he had been impressed by
2236-598: A gaming platform, and Microsoft CEO Bill Gates briefly considered buying the company. When id declined, Microsoft made its own licensed port, with a team led by Gabe Newell . One promotional video for Windows 95 had Gates digitally superimposed into the game. Other official ports of Doom were released for the 32X and Atari Jaguar in 1994, SNES and PlayStation in 1995, 3DO in 1996, Sega Saturn in 1997, Acorn Risc PC in 1998, Game Boy Advance in 2001, Xbox 360 in 2006, iOS in 2009, and Nintendo Switch , Xbox One , PlayStation 4 , and Android in 2019, with
2408-491: A large performance hit when anti-aliasing was enabled. 3dfx was fully aware of the Voodoo 5's speed deficiency, so they touted it as quality over speed, which was a reversal of the Voodoo 3 marketing which emphasized raw performance over features. 5500 sales were respectable but volumes were not at a level to keep 3dfx afloat. On March 28, 2000, 3dfx bought GigaPixel for US$ 186 million, in order to help launch its Rampage product to market quicker. GigaPixel had previously almost won
2580-545: A larger expression set to minimize the number of instructions the machines need to use. Based on a recognition that only a few instructions are commonly used, RISC shrinks the instruction set for added simplicity, which also enables the inclusion of more registers . After the invention of RISC in the 1980s, RISC based architectures that used pipelining and caching to increase performance displaced CISC architectures, particularly in applications with restrictions on power usage or space (such as mobile phones ). From 1986 to 2003,
2752-544: A long-running meme , "Can it run Doom ?" and "It runs Doom ". Upon its release in December 1993, Doom became an "overnight phenomenon". It was an immediate financial success for id, making a profit within a day after release. Although the company estimated that only 1% of shareware downloaders bought the full game, this was enough to generate initial daily revenue of US$ 100,000 , selling in one day what Wolfenstein had sold in one month. By May 1994, Wilbur said that

Cheat codes allow the player to unlock all weapons, walk through walls, or become invulnerable. Two multiplayer modes are playable over a network: cooperative , in which two to four players team up to complete the main campaign, and deathmatch , in which two to four players compete to kill
3096-593: A new video game console hardware platform. Sega solicited two competing designs: a unit code-named "Katana", developed in Japan using NEC and Imagination Technologies (then VideoLogic ) technology, and "Blackbelt", a system designed in the United States using 3dfx technology. However, on July 22, 1997, 3dfx announced that Sega was terminating the development contract. Sega chose to use NEC's PowerVR chipset for its game console, though it still planned to purchase
3268-568: A new game. Following the release of Wolfenstein 3D: Spear of Destiny in September 1992, the team began to plan their next game. They were tired of Wolfenstein and wanted to create another 3D game using a new engine Carmack was developing. Co-founder and lead designer Tom Hall proposed a new game in the Commander Keen series, but the team decided that the Keen platforming gameplay was
3440-686: A null driver test in Windows NT . Voodoo Banshee supports MPEG2 video acceleration. The Voodoo 3 was hyped as the graphics card that would make 3dfx the undisputed leader, but the actual product was below expectations. Though it was still the fastest as it edged the RIVA TNT2 by a small margin, the Voodoo3 lacked 32-bit color and large texture support. Though at that time few games supported large textures and 32-bit color, and those that did generally were too demanding to be run at playable framerates,
3612-415: A poor fit for Carmack's fast-paced 3D engines. Additionally, the other co-founders, designer John Romero and lead artist Adrian Carmack (no relation to John Carmack) wanted to create something in a darker style than the Keen games. John Carmack conceived a game about using technology to fight demons, inspired by a Dungeons & Dragons campaign the team played . This campaign would also influence

In 1936, Alan Turing developed the universal Turing machine to model any type of computer, proving that no computer would be able to solve the decision problem . The universal Turing machine was a type of stored-program computer capable of mimicking the operations of any Turing machine (computer model) based on the software instructions passed to it. The storage of computer programs

It sold an estimated 3.5 million copies by 1999, and up to 20 million people are estimated to have played it within two years of launch. It has been termed the "father" of first-person shooters and is regarded as one of the most important games in the genre. It has been cited by video game historians as shifting the direction and public perception of
4128-531: A severe bug resulting in data corruption on the AGP bus on certain boards, and was limited to AGP 2x. It was thus incompatible with the new Pentium 4 motherboards. Only a few more than one thousand units of the graphics card were ever produced. Later tests proved that the Voodoo 5 6000 outperformed not only the GeForce 2 GTS and ATI Radeon 7200 , but also the faster GeForce 2 Ultra and Radeon 7500 . In some cases it
4300-463: A significant constraint for manufacturers seeking to sell their products for less money than competitors offering a very similar commodity . Profit margins have also been reduced. Even when the performance is not increasing, the cost of components has been dropping over time due to improved manufacturing techniques that have fewer components rejected at quality assurance stage. The most common instruction set architecture (ISA)—the interface between

Sega quickly quashed 3dfx's "Blackbelt" and used the NEC-based "Katana" as the model for the product that would be marketed and sold as the Dreamcast . 3dfx sued Sega for breach of contract, accusing Sega of starting
4644-506: A significant performance advantage over the Voodoo3. The 3dfx Voodoo3 2000 PCI was the highest-performance 2D/3D card available for the Apple Macintosh at the time of its release, though support from 3dfx was labeled as 'beta' and required a firmware reflash. As game developers switched to DirectX and OpenGL , which respectively had become the industry standard and were becoming increasingly popular, 3dfx released its Glide API under
4816-471: A single pass. The Voodoo2 required three chips and a separate VGA graphics card, whereas new competing 3D products, such as the ATI Rage Pro, Nvidia RIVA 128 , and Rendition Verite 2200, were single-chip products. Despite some shortcomings, such as the card's dithered 16-bit 3D color rendering and 800x600 resolution limitations, no other manufacturers' products could match the smooth framerates that
4988-505: A slightly upgraded Voodoo Graphics chipset with an extra texture mapping unit and additional texture memory. The Voodoo Rush was 3dfx's first commercial failure. Sales were very poor, and the cards were discontinued within a year. The 3dfx Voodoo2, the successor to the Voodoo Graphics chipset released in March 1998, was architecturally similar, but the basic board configuration added a second texturing unit, allowing two textures to be drawn in

The only other member of the Voodoo 5 line, the Voodoo 4 4500, was as much of a disaster as Voodoo Rush, because it had performance well short of its value-oriented peers combined with a late launch. Voodoo 4 was beaten in almost all areas by the GeForce 2 MX—a low-cost board sold mostly as an OEM part for computer manufacturers—and
7912-469: The Pentium . By the end of 1997, the Voodoo Graphics was by far the most widely adopted 3D accelerator among both consumers and software developers. The Voodoo's primary competition was from PowerVR and Rendition . PowerVR produced a similar 3D-only add-on card with capable 3D support, although it was not comparable to Voodoo Graphics in either image quality or performance. 3dfx saw intense competition in
8084-671: The Radeon VE . One unusual trait of the Voodoo 4 and 5 was that the Macintosh versions of these cards had both VGA and DVI output jacks, whereas the PC versions had only the VGA connector. Also, the Mac versions of the Voodoo 4 and 5 had a weakness in that they did not support hardware-based MPEG2 decode acceleration, which hindered the playback of DVDs on a Mac equipped with a Voodoo graphics card. The Voodoo 5 6000 never made it to market, due to

Babbage also designed a general-purpose computer that was never built. Much of the design was incorporated into the earliest computers: punch cards for input and output, memory , an arithmetic unit analogous to central processing units , and even
9116-514: The 3dfx acquisition also approached Nvidia as a potential partner to acquire the company. At the time, STB was Nvidia's largest customer and was only minimally engaged with 3dfx. 3dfx management mistakenly believed that acquiring STB would ensure OEM design wins with their products and that product limitations would be overcome with STB's knowledge in supporting the OEM sales/design win cycles. Nvidia decided not to acquire STB and to continue to support many brands of graphics board manufacturers. After STB

12556-405: The best video games ever for nearly three decades since its release. In 1995, Next Generation said it was "the most talked about PC game ever". The PC version was ranked the 3rd best video game by Flux in 1995, and in 1996 was ranked fifth best and third most innovative by Computer Gaming World . In 2000, Doom was ranked as the second-best game ever by GameSpot . The following year, it
12728-568: The boxy, flat level designs failed to innovate on Wolfenstein , and failed to show off the engine's capabilities. He began to create his own, more abstract levels, which the rest of the team saw as a great improvement. Hall was upset with the reception of his designs and how little impact he was having as the lead designer. He was also upset with how much he was having to fight with John Carmack to get what he saw as obvious gameplay improvements, such as flying enemies, and began to spend less time at work. The other developers, however, felt that Hall
12900-405: The business team, planned the marketing and distribution of Doom . As id would make the most money from copies they sold directly to customers—up to 85% of the planned US$ 40 price—he decided to leverage the shareware market as much as possible. He believed that the mainstream press was uninterested in the game and bought only a single ad in any gaming magazine. Instead, he gave software retailers
13072-474: The contract to build Microsoft 's Xbox console, but lost out to Nvidia. However, in late 2000, not long after the launch of the Voodoo 4, several of 3dfx's creditors decided to initiate bankruptcy proceedings. 3dfx, as a whole, would have had virtually no chance of successfully contesting these proceedings, and instead opted to sell its assets to Nvidia, effectively ceasing to exist as a company. The resolution and legality of those arrangements (with respect to
13244-407: The creation of the X series of video cards and the development of Crossfire , their own version of SLI. The prototype Spectre 1000 cards were delivered to software developers mere days before declaring insolvency. The software team developed both device drivers and a binary-compatible soft emulation of the Rampage function set. Thus, there were working Windows NT device drivers within a few days of
13416-463: The dead". The press release proclaimed the new 3D engine features that John Carmack had created, as well as aspects including multiplayer, that had not yet even been designed. Early versions were built to match the Doom Bible , and a "pre-alpha" version of the first level included Hall's introductory base scene. Initial versions also retained Wolfenstein ' s arcade -style scoring , but this
13588-543: The deal in bad faith in order to take 3dfx technology. The case was settled out of court. In early 1998, 3dfx embarked on a new development project. The Rampage development project was new technology for use in a new graphics card that would take approximately two years to develop, and would supposedly be several years ahead of the competition once it debuted. The company hired hardware and software teams in Austin, Texas to develop 2D and 3D Windows device drivers for Rampage in
13760-399: The defeat of a gigantic cyberdemon. From an overlook, he discovers that the moon is floating above hell and rappels down to the surface. In "Inferno", the marine battles through hell itself and destroys a cybernetic spider-demon that masterminded the invasion of the moons. When a portal to Earth opens, the marine steps through to discover that Earth has been invaded. "Thy Flesh Consumed" follows
13932-572: The design for a computer (the Automatic Computing Engine ) that was never built. Around this time, technological advancement in relays and vacuum tubes enabled the construction of the first computers. Building on Babbage's design, relay computers were built by George Stibitz at Bell Laboratories and Harvard University 's Howard Aiken , who engineered the MARK I . Also in 1945, mathematician John von Neumann —working on
14104-574: The design of Quake (1996) and Daikatana (2000). More broadly the team intended to combine the styles of the Evil Dead II and Aliens films. The working title was Green and Pissed , but Carmack renamed it Doom based on a line from the 1986 film The Color of Money : " 'What you got in there?' / 'In here? Doom. ' " The team agreed to pursue the Doom concept, and development began in November 1992. The initial development team
14276-443: The design of the CPU, memory, and memory interconnect . Memory hierarchy ensures that the memory quicker to access (and more expensive) is located closer to the CPU, while slower, cheaper memory for large-volume storage is located further away. Memory is typically segregated to separate programs from data and limit an attacker's ability to alter programs. Most computers use virtual memory to simplify addressing for programs, using
14448-511: The development team at id uploaded the first episode to the internet, letting interested players distribute it for them. The team was unable to connect to the FTP server at the University of Wisconsin–Madison where they planned to upload the game, since there were so many users already connected in anticipation of the release. The network administrator was forced to first increase the number of connections, and then kick off all users to make room. When
14620-435: The drivers do not carry a manufacturer's backing and are considered beta software. For a limited time, Nvidia offered a program under which 3dfx owners could trade in their cards for Nvidia cards of similar performance. On December 15, 2000, 3dfx apologized to the customers with a final press release. In 2003, the source code for 3dfx drivers leaked , resulting in fan-made , updated drivers and further support. Although 1997
14792-563: The engine, Carmack began to use binary space partitioning to quickly select the reduced portion of a level that the player could see at a given time. Taylor, along with programming other features, added cheat codes to aid in development and left them in for players. Adrian Carmack was the lead artist for Doom , with Kevin Cloud as an additional artist. They designed the monsters to be "nightmarish", with graphics that were realistic and dark instead of staged or rendered. A mixed media approach
14964-631: The external world or write data respectively. Common examples include keyboards and mice (input) and displays and printers (output). Network interface controllers are used to access the Internet . USB ports also allow power to connected devices—a standard USB supplies power at 5 volts and up to 500 milliamps (2.5 watts ), while powered USB ports with additional pins may allow the delivery of more power—up to 6 amps at 24v. Global revenue from computer hardware in 2023 reached $ 705.17 billion. Because computer parts contain hazardous materials, there
15136-411: The fact it is hard or rigid with respect to changes, whereas software is soft because it is easy to change. Hardware is typically directed by the software to execute any command or instruction . A combination of hardware and software forms a usable computing system, although other systems exist with only hardware. Early computing devices were more complicated than the ancient abacus date to
15308-575: The features "32-bit color support" and "2048×2048 textures" were much more impressive on paper than 16-bit color and 256×256 texture support. The Voodoo3 sold relatively well, but was disappointing compared to the first two models and 3dfx lost the market leadership to Nvidia. As 3dfx attempted to counter the TNT2 threat, it was surprised by Nvidia's GeForce 256 . The GeForce was a single-chip processor with integrated transform, lighting, triangle setup/clipping (hardware T&L), and rendering engines, giving it
15480-649: The final level of each focusing on a boss fight . While traversing the levels, the player must fight a variety of enemies, including demons and possessed undead humans. Enemies often appear in large groups. The five difficulty levels adjust the number of enemies and amount of damage they do, with enemies moving and attacking faster than normal on the hardest difficulty setting. The monsters have simple behavior: they move toward their opponent if they see or hear them, and attack by biting, clawing, or using magic abilities such as fireballs. The player must manage supplies of ammunition, health , and armor while traversing
15652-417: The first 3dfx card to be developed in-house rather than by third-party manufacturers, which were a significant source of revenue for the company. These third-party manufacturers turned into competitors and began sourcing graphics chips from Nvidia. This also further alienated 3dfx's remaining OEM customers, as they had a single source for 3dfx products and could not choose an OEM to provide cost flexibility. With
15824-534: The game calculates the "light level" of a small area based on the predetermined brightness of said area. It then modifies the color palette of that section's surface textures to mimic how dark it would look. This same system is used to cause far away surfaces to look darker than close ones. Romero came up with new ways to use Carmack's lighting engine, such as strobe lights. He programmed engine features such as switches and movable stairs and platforms. After Romero's complex level designs started to cause problems with
15996-476: The game data, id provided no instructions for how they worked. Still, players were able to modify leaked alpha versions of the game, allowing them to release level editors within weeks of the game's release. On January 26, 1994, university student Brendon Wyber led a group to create the first full level editor , the Doom Editor Utility, leading to the first custom level by Jeff Bird in March. It
16168-547: The game had sold over 65,000 copies, and estimated that the shareware version had been distributed over 1 million times. In 1995, Wilbur estimated the first-year sales as 140,000, while in 2002 Petersen said it had sold around 200,000 copies in its first year. By late 1995, Doom was estimated to be installed on more computers worldwide than Microsoft's new operating system, Windows 95 . According to PC Data , by April 1998 Doom ' s shareware edition had yielded 1.36 million units sold and US$ 8.74 million in revenue in
16340-420: The game's engine, including LucasArts 's Star Wars: Dark Forces (1995). Several other games termed Doom clones, such as PowerSlave (1996) and Duke Nukem 3D (1996), used the 1995 Build engine , a 2.5D engine inspired by Doom created by Ken Silverman with some consultation with John Carmack. After completing Doom , id Software began working on a sequel using the same engine, Doom II , which
16512-639: The game's levels in order to meet the console's launch date, while the PlayStation port includes The Ultimate Doom and Doom II . The source code for Doom was released under a non-commercial license in 1997, and freely released under the GNU General Public License in 1999. Due to the release of its source code, Doom has been unofficially ported to numerous platforms. These ports include esoteric devices such as smart thermostats, pianos, and Doom itself, which led to variations of
16684-493: The games released in the intervening years. Doom , and to a lesser extent Wolfenstein 3D , has been characterized as "mark[ing] a turning point" in the perception of video games in popular culture, with Doom and first-person shooters in general becoming the predominant perception of video games in media. Historians such as Tristan Donovan in Replay: The History of Video Games (2010) have termed it as causing
16856-503: The genre. Id Software licensed the Doom engine to several other companies, which resulted in several games similar to Doom , including Heretic (1994), Hexen: Beyond Heretic (1995), and Strife: Quest for the Sigil (1996). A Doom -based game called Chex Quest was released in 1996 by Ralston Foods as a promotion to increase cereal sales. Other games were inspired by Doom , if not rumored to be built by reverse engineering
17028-400: The graphics and levels but criticized the straightforward shooting gameplay. The review concluded: "If only you could talk to these creatures, then perhaps you could try and make friends with them, form alliances... Now, that would be interesting." The review attracted mockery and "if only you could talk to these creatures" became a running joke in video game culture . The multiplayer gameplay
17200-422: The graphics excellent and unlike any other game's. PC Zone , Dragon , Computer Gaming World , and Electronic Entertainment all praised the atmosphere and art direction, saying that the level design, lighting effects, and sound effects combined to create a "claustrophobic" and "nightmarish experience". Computer Gaming World also praised the music, as did The Mercury News , which called it as "ominous as
17372-461: The hardware from excessive heat, the system will automatically reduce performance or shut down the processor if necessary. Processors also will shut off or enter a low power mode when inactive to reduce heat. Power delivery as well as heat dissipation are the most challenging aspects of hardware design, and have been the limiting factor to the development of smaller and faster chips since the early twenty-first century. Increases in performance require
17544-616: The history of video games. It has also been used in scholarly research since its release, including for machine learning , video game aesthetics and design, and the effects of video games on aggression, memory, and attention. In 2007 Doom was listed among the ten " game canon " video games selected for preservation by the Library of Congress , and in 2015 The Strong National Museum of Play inducted Doom to its World Video Game Hall of Fame as part of its initial set of games. Doom has continued to be included highly in lists of
17716-513: The intensity. Id only gave a single press preview, to Computer Gaming World in June, to a glowing response, but had also released development updates to the public continuously throughout development on the nascent internet . Id began receiving calls from people interested in the game or angry that it had missed its planned release date, as anticipation built over the year. At midnight on December 10, 1993, after working for 30 straight hours testing,
17888-409: The killing would be "like playing Doom ". A rumor spread afterward that Harris had designed a custom Doom level that looked like the high school, populated with representations of Harris's classmates and teachers, which he used to practice for the shooting. Although Harris did design several custom Doom levels, which later became known as the " Harris levels ", none were based on the school. Doom
18060-480: The latter-most platforms (excluding Android) receiving a further expanded port alongside Doom II in 2024 along with ports for the PlayStation 5 and Xbox Series X/S . Some of these became bestsellers even many years after the initial release. The ports did not all have the same content, with some having fewer levels, such as the 32X port created by John Carmack, which was released with only two-thirds of
18232-412: The level design. John Carmack not only disliked the proposed story but dismissed the idea of having a story at all: "Story in a game is like story in a porn movie; it's expected to be there, but it's not that important." Rather than a deep story, he wanted to focus on technological innovation, dropping the levels and episodes of Wolfenstein in favor of a fast, continuous world. Hall disliked the idea, but
18404-507: The level of the RIVA TNT2 . However, Napalm was delayed, and in the meantime Nvidia brought out their landmark GeForce 256 chip, which shifted even more of the computational work from the CPU to the graphics chip. Napalm would have been unable to compete with the GeForce, so it was redesigned to support multiple chip configurations, like the Voodoo2 had. The end-product was named VSA-100, with VSA standing for Voodoo Scalable Architecture. 3dfx
18576-455: The levels. The player can find weapons and ammunition throughout the levels or can collect them from dead enemies, including a pistol, a shotgun , a chainsaw , a plasma rifle , and the BFG 9000 . The player also encounters pits of toxic waste , ceilings that lower and crush objects, and locked doors requiring a collectable keycard or a remote switch. Power-ups include health or armor points,
18748-451: The limited amount of additional content and recommended it only to major fans or those who had not played it. Fusion reviewed the edition positively, praising the difficulty of the new levels, as did GameSpot , which reviewed it from the perspective of introducing the game to new players. The first ports of Doom received comparable reviews to the original PC version. VideoGames , GamePro , and Computer and Video Games all gave
18920-522: The load. In 1995, id created an expanded version of Doom for the retail market with a fourth episode of levels, which was published by GT Interactive as The Ultimate Doom . Doom has also been ported to numerous different platforms, independent from id Software. The first port of Doom was an unofficial port to Linux, released by id programmer Dave Taylor in 1994; it was hosted by id but not supported or made official. Microsoft attempted to hire id to port Doom to Windows in 1995 to promote Windows as
19092-525: The lungs, liver, and kidneys. Computer components contain many toxic substances, like dioxins , polychlorinated biphenyls (PCBs), cadmium , chromium , radioactive isotopes and mercury . Circuit boards contain considerable quantities of lead-tin solders that are more likely to leach into groundwater or create air pollution due to incineration. Recycling of computer hardware is considered environmentally friendly because it prevents hazardous waste , including heavy metals and carcinogens, from entering
19264-500: The mainstream consumer market. A single-chip solution, the Banshee was a combination of a 2D video card and partial (only one texture mapping unit ) Voodoo2 3D hardware. Due to the missing second TMU , in 3D scenes which used multiple textures per polygon , the Voodoo2 was significantly faster. However, in scenes dominated by single-textured polygons, the Banshee could match or exceed the Voodoo2 due to its higher clock speed and resulting greater pixel fillrate. Banshee's 2D acceleration
19436-564: The marine's initial assault on the Earth invaders, setting the stage for Doom II . Id Software released Wolfenstein 3D in May 1992. Later called the "grandfather of 3D shooters", it established the genre's popularity and its reputation for fast action and technological advancement. When most of the studio began work on additional episodes for Wolfenstein , id co-founder and lead programmer John Carmack instead began technical research on
19608-472: The market from cards that offered the combination of 2D and 3D acceleration. While these cards, such as the Nvidia NV1 , Matrox Mystique , S3 ViRGE , Vérité V1000 , and ATI 3D Rage , offered inferior 3D acceleration in terms of image quality, performance, or both, their lower cost and simplicity often appealed to OEM system builders. In 1997, 3dfx was working with entertainment company Sega to develop
19780-420: The medium as a whole, as well as sparking the rise of online games and communities. It led to an array of imitators and clones , as well as a robust modding scene and the birth of speedrunning as a community. Its high level of graphic violence led to controversy from a range of groups. Doom has been ported to a variety of platforms both officially and unofficially and has been followed by several games in
19952-506: The metal plates. Resistors, semiconductors, infrared detectors, stabilizers, cables, and wires contain cadmium. The circuit boards in a computer contain mercury, and chromium. When these types of materials, and chemicals are disposed improperly will become hazardous for the environment. When e-waste byproducts leach into groundwater, are burned, or get mishandled during recycling, it causes harm. Health problems associated with such toxins include impaired mental development, cancer, and damage to
20124-416: The military to conduct secret teleportation experiments that turn deadly. A base on Phobos urgently requests military support, while Deimos disappears entirely, and the marine joins a combat force to secure Phobos. He waits at the perimeter as ordered while the entire assault team is wiped out. With no way off the moon, and armed with only a pistol, he enters the base intent on revenge. In "Knee-Deep in
20296-474: The monitor. The method used to engage the Voodoo's output circuitry varied between cards, with some using mechanical relays while others utilized purely solid-state components. The mechanical relays emitted an audible "clicking" sound when they engaged and disengaged. In August 1997, 3dfx released the Voodoo Rush chipset, combining a Voodoo chip with a 2D chip that lay on the same circuit board, eliminating
20468-437: The most imitated game of all time". These games were often referred to as " Doom clones ", with "first-person shooter" only overtaking it as the name of the genre after a few years. As the "first-person shooter" genre label had not yet solidified at the time, Doom was described as a "first person perspective adventure" and "atmospheric 3-D action game". Doom clones ranged from close imitators to more innovative takes on
20640-443: The motherboard include: An expansion card in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus. Expansion cards can be used to obtain or expand on features not offered by the motherboard. Using expansion cards for a video processor used to be common, but modern computers are more likely to instead have
20812-403: The multiplayer component was coded, the development team began playing four-player games, which Romero termed "deathmatch", and Cloud named the act of killing other players " fragging ". According to Romero, the deathmatch mode was inspired by fighting games such as Street Fighter II , Fatal Fury , and Art of Fighting . Doom was written largely in the C programming language, with
20984-402: The need for a separate VGA card. Most cards were built with an Alliance Semiconductor AT25/AT3D 2D component, but there were some built with a Macronix chip and there were initial plans to partner with Trident but no such boards were ever marketed. The Rush had the same specifications as Voodoo Graphics, but did not perform as well because the Rush chipset had to share memory bandwidth with
21156-410: The option to sell copies of the first Doom episode at any price, in hopes of motivating customers to buy the full game directly from id. The team planned to release Doom in the third quarter of 1993 but ultimately needed more time. By December 1993, the team was working non-stop, with several employees sleeping at the office. Taylor said that the work gave him such a rush that he would pass out from
21328-466: The other players' characters as many times as possible. Multiplayer was initially only playable over local networks, but a four-player online multiplayer mode was made available one year after launch through the DWANGO service. Doom is divided into three episodes, each containing about nine levels: "Knee-Deep in the Dead", "The Shores of Hell", and "Inferno". A fourth episode, "Thy Flesh Consumed",
21500-403: The others. The weapons were made from combined parts of children's toys. The developers photographed themselves as well, using Cloud's arm for the marine's arm holding a gun, and Adrian's snakeskin boots and wounded knee for textures. The cover art was created by Don Ivan Punchatz , Gregor Punchatz's father, who worked from a short description of the game rather than detailed references. Romero
21672-422: The physical parts of a computer , such as the central processing unit (CPU), random access memory (RAM) , motherboard , computer data storage , graphics card , sound card , and computer case . It includes external devices such as a monitor , mouse , keyboard , and speakers . By contrast, software is a set of written instructions that can be stored and run by hardware. Hardware derived its name from
21844-642: The power on of the Rampage system on the 2nd week of December, 2000. At the time of Nvidia's acquisition, 3dfx had already been developing the successors to Spectre. "Fear", based on a next-generation Rampage called Fusion, and Sage2. "Mojo" would combine both into a single die, implement tiled rendering , and showcase some advanced technologies from the GigaPixel acquisition. The unreleased Spectre 1000 card, based on Rampage, would eventually be leaked and tested. Performance indicated that it would have struggled to compete with Nvidia's already-released GeForce 256, though
22016-416: The proposed Spectre 2000 and Spectre 3000 cards, which featured a combination of Rampage and Sage units, would have led the market until late 2002, with Nvidia's GeForce 4 series . After Nvidia acquired 3dfx's intellectual property, they announced that they would not provide technical support for 3dfx products. As of 2019, drivers and support are still offered by community websites. However, while functional,
22188-470: The publisher and could make more money by self-publishing. In November, Hall delivered a design document that he called the "Doom Bible", detailing the project's plot, backstory, and design goals. His design was a science fiction horror concept wherein scientists on the Moon open a portal to an alien invasion. Over a series of levels, the player discovers that the aliens are demons while hell steadily infects
22360-510: The purchase of STB, 3dfx created two cards targeting the low-end market, the Velocity 100, which has 8 MB of SDRAM , and the Velocity 200, which has 16 MB of SGRAM . The cards both used a chipset based on the Voodoo3 2000, and it was claimed that they were "underclocked". However, it was revealed by testing that the Velocity 100 chipset has the same clock speed as a typical Voodoo3 2000—at 143 MHz—and that, while one of its two TMUs
22532-480: The purchase, 3dfx's creditors and its bankruptcy proceedings) took over a decade to resolve in the federal courts. Specifically, the trustee of 3dfx's bankruptcy estate challenged 3dfx's sale of its assets to Nvidia as an allegedly fraudulent conveyance . On November 6, 2014, in an unpublished memorandum order, the U.S. Court of Appeals for the Ninth Circuit affirmed the "district court's judgment affirming
22704-552: The recycling of computer hardware, refers to the donation, reuse, shredding and general collection of used electronics. Generically, the term refers to the process of collecting, brokering, disassembling, repairing and recycling the components or metals contained in used or discarded electronic equipment, otherwise known as electronic waste (e-waste). E-cyclable items include, but are not limited to: televisions, computers, microwave ovens, vacuum cleaners, telephones and cellular phones, stereos, and VCRs and DVDs just about anything that has
22876-452: The rest of the team sided with Carmack. Hall spent the next few weeks reworking the Doom Bible to work with Carmack's technological ideas. However, the team then realized that Carmack's vision for a seamless world would be impossible given the hardware limitations, and Hall was forced to rework the design document once again. At the start of 1993, id put out a press release, touting Hall's story about fighting off demons while "knee-deep in
23048-519: The rights to 3dfx's technology in order to prevent competitors from acquiring it. 3dfx said Sega has still not given a reason as to why it terminated the contract or why it chose NEC's accelerator chipset over 3dfx's. According to Dale Ford, senior analyst at Dataquest, a market research firm based in San Jose, California, a number of factors could have influenced Sega's decision to move to NEC, including NEC's proven track record of supplying chipsets for
23220-646: The same function is running across multiple areas of data ( data parallelism ) or different tasks can be performed simultaneously with limited interaction ( task parallelism ). These forms of parallelism are accommodated by various hardware strategies, including instruction-level parallelism (such as instruction pipelining ), vector architectures and graphical processing units (GPUs) that are able to implement data parallelism, thread-level parallelism and request-level parallelism (both implementing task-level parallelism). Microarchitecture , also known as computer organization, refers to high-level hardware questions such as
23392-412: The scenario". The Ultimate Doom received mixed reviews upon its release in 1995, as in the review from PC Zone , which gave it a score of 90/100 for new players but 20/100 for anyone who had the original game. The reviewer viewed it as solely a level pack due to the lack of new features and compared it negatively to the hundreds of free fan-made levels available on the internet. Joystick disliked
23564-424: The series, including Doom II (1994), Doom 64 (1997), Doom 3 (2004), Doom (2016), Doom Eternal (2020), and Doom: The Dark Ages (2025), as well as the films Doom (2005) and Doom: Annihilation (2019). Doom is a first-person shooter presented with 3D graphics . While the environment is shown in a 3D perspective, the enemies and objects are instead 2D sprites rendered at fixed angles,
23736-423: The seventeenth century. French mathematician Blaise Pascal designed a gear-based device that could add and subtract, selling around 50 models. The stepped reckoner was invented by Gottfried Leibniz by 1676, which could also divide and multiply. Due to the limitations of contemporary fabrication and design flaws, Leibniz' reckoner was not very functional, but similar devices ( Leibniz wheel ) remained in use into
23908-449: The six-month product refresh cycle the computer manufacturers required; 3dfx did not have the methodology nor the mindset to focus on this business model. In the end, 3dfx opted to be a retail distribution company manufacturing their own branded products. The company's final product was code-named Napalm. Originally, this was just a Voodoo3 modified to support newer technologies and higher clock speeds, with performance estimated to be around
24080-504: The sounds to be distinct on the limited sound hardware of the time, even when many sounds were playing at once. He also designed the sound effects to play on different frequencies from those used for the MIDI music, so they would clearly cut through the music. Id Software planned to self-publish Doom for DOS -based computers and set up a distribution system leading up to the release. Jay Wilbur, who had been hired as CEO and sole member of
24252-569: The storage problem by locating programs and data adjacent to each other created the Von Neumann bottleneck when the system tries to fetch both at the same time—often throttling the system's performance. Computer architecture requires prioritizing between different goals, such as cost, speed, availability, and energy efficiency. The designer must have a good grasp of the hardware requirements and many different aspects of computing, from compilers to integrated circuit design. Cost has also become
24424-435: The story were removed from the project, with the final game featuring an action-heavy design by John Romero and Sandy Petersen . Id published Doom as a set of three episodes under the shareware model, marketing the full game by releasing the first episode free. A retail version with an additional episode was published in 1995 by GT Interactive as The Ultimate Doom . Doom was a critical and commercial success, earning
24596-466: The summer of 1998. The hardware team in Austin initially focused on Rampage, but then worked on transform and lighting (T&L) engines and on MPEG decoder technology. 3dfx announced in January 1999 that their Banshee cards had sold about one million units. While Nvidia had yet to launch a product in the add-in board market that sold as well as 3dfx's Voodoo line, the company was gaining steady ground in
24768-410: The team believed it emphasized realism over entertaining gameplay, and they did not see the need for a design document at all. Some ideas were retained, but the story was dropped and most of the design was removed. By early 1993, Hall created levels that became part of an internal demo. Carmack and Romero, however, rejected the military architecture of Hall's level design. Romero especially believed that
24940-443: The team, and Romero incorporated both. Prince did not make music for specific levels, as they were composed before the levels were completed. Instead, Romero assigned each track to each level late in development. Prince created the sound effects based on short descriptions or concept art of a monster or weapon and adjusted them to match the completed animations. The monster sounds were created from animal noises, and Prince designed all
25112-603: The technology would be later used to link the VSA-100 chips on the Voodoo 5. The arrival of the Nvidia RIVA TNT with integrated 2D/3D chipset would offer minor challenge to the Voodoo2's supremacy months later. Near the end of 1998, 3dfx released the Voodoo Banshee , which featured a lower price achieved through higher component integration, and a more complete feature-set including 2D acceleration, to target
25284-449: The unit. Hobbyists may decorate the cases with colored lights, paint, or other features, in an activity called case modding . Most personal computer power supply units meet the ATX standard and convert from alternating current (AC) at between 120 and 277 volts provided from a power outlet to direct current (DC) at a much lower voltage: typically 12, 5, or 3.3 volts. The motherboard
25456-506: The upload finished 30 minutes later, 10,000 people attempted to download the game at once, crashing the university's network. Within hours of Doom ' s release, university networks began banning Doom multiplayer games, as a rush of players overwhelmed their systems. The morning after release, John Carmack quickly released a patch in response to complaints of network congestion from administrators, who still needed to implement Doom -specific rules to keep their networks from crashing from
25628-482: The variety of monsters and weapons. Computer Gaming World concluded that it was "a virtuoso performance". Other reviewers, while also praising the gameplay, commented on the lack of complexity: Computer and Video Games found it captivating and praised the variety and complexity of the level design, but called the overall gameplay repetitive, while Dragon similarly praised the fast gameplay and level design, but said that overall it lacked depth. Edge praised
25800-485: Was accelerated by the introduction of Microsoft's Direct3D , which provided a single high-performance API that could be implemented on these cards, seriously eroding the value of Glide. While 3dfx continued to offer high-performance options, the value proposition was no longer compelling. 3dfx rapidly declined in the late 1990s and most of the company's assets were acquired by Nvidia Corporation on December 15, 2000, mostly for intellectual property rights . The acquisition
25972-456: Was accounted for as a purchase by Nvidia and was completed by the first quarter of their fiscal year of 2002. 3dfx ceased supporting their products on February 15, 2001, and filed for bankruptcy on October 15, 2002. The company was founded on August 24, 1994, as 3D/fx, Inc. Ross Smith, Gary Tarolli and Scott Sellers, all former employees of Silicon Graphics Inc. They were soon joined by Gordie Campbell of TechFarm. 3dfx released its first product,
26144-639: Was acquired by 3dfx, Nvidia focused on being a virtual graphics card manufacturer for the OEMs and strengthened its position in selling finished reference designs ready for market to the OEMs. STB's manufacturing facility in Juarez, Mexico was not able to compete from either a cost or quality point of view when compared to the burgeoning original design manufacturers (ODMs) and Contract electronic manufacturers (CEMs) that were delivering solutions in Asia for Nvidia. Prior to
26316-493: Was added in an expanded version, The Ultimate Doom , released two years after Doom . The campaign contains very few plot elements, with a minimal story presented mostly through the instruction manual and text descriptions between episodes. In the future, an unnamed marine is posted to a dead-end assignment on Mars after assaulting a superior officer who ordered his unit to fire on civilians. The Union Aerospace Corporation, which operates radioactive waste facilities there, allows
26488-592: Was because it found that no existing APIs at the time could fully utilize the chip's capabilities. DirectX 3.0 was deemed to be lacking, and OpenGL was regarded as suitable only for CAD/CAM workstations. The first graphics card to use the chip was Orchid Technology 's Righteous 3D, released on October 7, 1996. The company manufactured only the chips and some reference boards, and initially did not sell any product to consumers; rather, it acted as an OEM supplier for graphics card companies, which designed, manufactured, marketed, and sold their own graphics cards including
26660-431: Was composed of five people: programmers John Carmack and Romero, artists Adrian Carmack and Kevin Cloud , and designer Hall. They moved operations to a dark office building, naming it "Suite 666" while drawing inspiration from the noises they heard from a neighboring dental practice. They also decided to cut ties with Apogee Software , their previous publisher, and self-publish Doom , as they felt that they were outgrowing
26832-429: Was dubbed a "mass murder simulator" by critic and Killology Research Group founder David Grossman . In the earliest release versions, the level E1M4: Command Control contains a swastika -shaped structure, which was put in as a homage to Wolfenstein 3D . The swastika was removed in later versions, out of respect for a military veteran's request, according to Romero. Doom ' s popularity and innovations attracted
27004-444: Was finally able to have a product that could defeat the GeForce. However, by the time the VSA-100 based cards made it to the market, the GeForce 2 and ATI Radeon cards had arrived and were offering higher performance for the same price. The only real advantage the Voodoo 5 5500 had over the GeForce 2 GTS or Radeon was its superior spatial anti-aliasing implementation, and the fact that, relative to its peers, it did not suffer such
27176-428: Was followed by "countless" others, including many based on other franchises like Aliens and Star Wars total conversion mods , as well as DeHackEd, a patch editor first released in 1994 by Greg Lewis that allowed editing of the game engine. Soon after the first mods appeared, id CEO Wilbur posted legal terms to the company's website, allowing mod authors to charge money without any fees to id, while also absolving
27348-525: Was highly praised in contemporaneous reviews. In April 1994, a few months after release, PC Gamer UK named it the third-best computer game of all time, claiming " Doom has already done more to establish the PC's arcade clout than any other title in gaming history," and PC Gamer US named it the best computer game of all time that August. It won the Best Action Adventure award at Cybermania '94 . GamesRadar UK named Doom Game of
27520-440: Was later removed as it clashed with Doom ' s intended tone. The studio also experimented with other game systems before removing them, such as lives , an inventory, a secondary shield, and a complex user interface. Soon, however, the Doom Bible as a whole was rejected. Romero wanted a game even "more brutal and fast" than Wolfenstein , which did not leave room for the character-driven plot Hall had created. Additionally,
27692-536: Was marked by analysts as a turning point for 3dfx due to the marketing led by the new CEO Greg Ballard, there was criticism of Ballard's understanding of R&D in the graphics industry. Single-card 2D/3D solutions were taking over the market, and although Ballard saw the need and attempted to direct the company there with the Voodoo Banshee and the Voodoo3, both of these cost the company millions in sales and lost market share while diverting vital resources from
27864-407: Was not in sync with the team's vision and was becoming a problem. In July the other founders of id fired Hall, who went to work for Apogee. He was replaced by Sandy Petersen in September, ten weeks before the game was released. Petersen later recalled that John Carmack and Romero wanted to hire other artists instead, but Cloud and Adrian disagreed, saying that a designer was required to help build
28036-420: Was noted for weaker graphics and unresponsive controls, though reviewers such as Computer and Video Games , GamePro , and Next Generation were split on awarding high or middling scores due to these faults. Later 1990s ports received worse reviews; the 3DO port was panned by GamePro and Maximum for having worse graphics, a smaller screen size, and less intelligent enemies than any previous version, and
28208-520: Was notorious for its high levels of graphic violence and satanic imagery, which generated controversy from a broad range of groups. Doom for the 32X was one of the first video games to be given a Mature 17+ rating from the Entertainment Software Rating Board due to its violent gore and nature, while Doom II was the first. In Germany, shortly after its publication, Doom was classified as "harmful to minors" by
28380-531: Was one of the larger graphics card manufacturers at the time; the intent was for 3dfx to start manufacturing, marketing, and selling its own graphics cards, rather than functioning only as an OEM supplier. Purchase of STB was intended to give 3dfx access to that company's considerable OEM resources and sales channels, but the intended benefits of the acquisition never materialized. The two corporations were vastly different entities, with different cultures and structures, and they never integrated smoothly. STB prior to
28552-616: Was praised: Computer Gaming World called it "the most intense gaming experience available", and Dragon called it "the biggest adrenaline rush available on computers". PC Zone named it as the best multiplayer game available, in addition to the best arcade game. The 3D graphics and art style were praised by reviewers; Computer Gaming World called the graphics remarkable, while Edge said that it "made serious advances in what people will expect of 3D graphics in future", surpassing not only prior games but games that had yet to be released. Compute! and Electronic Games similarly called
28724-491: Was released to retail on October 10, 1994, ten months after the first game. GT Interactive had approached id before the release of Doom with plans to release a retail version of Doom and Doom II . Id chose to create the sequel as a set of episodes rather than a new game, allowing John Carmack and the other programmers to begin work on id's next game, Quake . Doom II was the United States' highest-selling software product of 1994 and sold more than 1.2 million copies within
28896-430: Was shown to compete well with the GeForce 3 , trading performance places with the card on various tests. However, the prohibitively high production cost of the card, particularly the 4 chip setup, external power supply and 128 MB of VRAM (which would have made it the first consumer card with that amount of memory), would have likely hampered its competitiveness. Computer hardware Computer hardware includes
29068-423: Was taken to create them. The artists sculpted models of some of the enemies and took pictures of them in stop motion from five to eight different angles so that they could be rotated realistically in-game. The images were then digitized and converted to 2D characters with a program written by John Carmack. Adrian Carmack made clay models for a few demons and had Gregor Punchatz build latex and metal sculptures of
29240-619: Was the body model used for cover; he posed during a photoshoot to demonstrate to the intended model what the pose should look like, and Punchatz used his photo. As with Wolfenstein 3D , id hired composer Bobby Prince to create the music and sound effects. Romero directed Prince to make the music in techno and metal styles. Many tracks were directly inspired by songs by metal bands such as Alice in Chains and Pantera . Prince believed that ambient music would be more appropriate and produced numerous tracks in both styles in hope of convincing
29412-586: Was the first such hardware from 3dfx and it was very capable. It rivaled the fastest 2D cores from Matrox , Nvidia, and ATI . It consisted of a 128-bit 2D GUI engine and a 128-bit VESA VBE 3.0 VGA core. The graphics chip capably accelerated DirectDraw and supported all of the Windows Graphics Device Interface (GDI) in hardware, with all 256 raster operations and tertiary functions, and hardware polygon acceleration. The 2D core achieved near-theoretical maximum performance with
29584-713: Was voted the number one game of all time in a poll among over 100 game developers and journalists conducted by GameSpy , and was ranked the sixth best game by Game Informer . GameTrailers ranked it the most "breakthrough PC game" in 2009 and Game Informer again ranked it the sixth-best game that same year. Doom has also been ranked among the best games of all time by GamesMaster , Hyper , The Independent , Entertainment Weekly , GamesTM , Jeuxvideo.com , Gamereactor , Time , Polygon , and The Times , among others, as recently as 2023. The success of Doom led to dozens of new first-person shooter games. In 1998, PC Gamer declared it "probably
