74-476: Capcom announced the development of the CP System II (or CPS-2) in 1990. They had planned to complete and release the CP System II hardware in 18 months. They also originally had plans for the system to be capable of 3D graphics . The earlier Capcom system board , the original CP System (or CPS-1), while successful, was very vulnerable to bootleggers making unauthorized copies of games. In order to rectify

148-495: A three-dimensional representation of geometric data (often Cartesian ) that is stored in the computer for the purposes of performing calculations and rendering digital images , usually 2D images but sometimes 3D images . The resulting images may be stored for viewing later (possibly as an animation ) or displayed in real time . 3-D computer graphics, contrary to what the name suggests, are most often displayed on two-dimensional displays. Unlike 3D film and similar techniques,

222-495: A 3D model is formed from points called vertices that define the shape and form polygons . A polygon is an area formed from at least three vertices (a triangle). A polygon of n points is an n-gon. The overall integrity of the model and its suitability to use in animation depend on the structure of the polygons. Before rendering into an image, objects must be laid out in a 3D scene . This defines spatial relationships between objects, including location and size . Animation refers to

296-464: A 3D model is intended to be a solid color, it must be painted with " textures " for realism. A bone/joint animation system is set up to deform the CGI model (e.g., to make a humanoid model walk). In a process known as rigging , the virtual marionette is given various controllers and handles for controlling movement. Animation data can be created using motion capture , or keyframing by a human animator, or

370-520: A 64-bit key. The algorithm was thereafter implemented in this state for all known CPS-2 games in MAME . In April 2016, Eduardo Cruz, Artemio Urbina and Ian Court announced the successful reverse engineering of Capcom's CP System II security programming, enabling the clean "de-suicide" and restoration of any dead games without hardware modifications. Capcom ceased manufacturing the CP System II hardware on December 22, 2003, with Hyper Street Fighter II being

444-400: A character's arms can have a skeleton applied, and the joints can have transformation and rotation keyframes set. The movement of the arm joints will then cause the arm shape to deform. 3D animation software interpolates between keyframes by generating a spline between keys plotted on a graph which represents the animation. Additionally, these splines can follow bezier curves to control how

518-599: A combination of the two. 3D models rigged for animation may contain thousands of control points — for example, "Woody" from Toy Story uses 700 specialized animation controllers. Rhythm and Hues Studios labored for two years to create Aslan in the movie The Chronicles of Narnia: The Lion, the Witch and the Wardrobe , which had about 1,851 controllers (742 in the face alone). In the 2004 film The Day After Tomorrow , designers had to design forces of extreme weather with

592-460: A computer - such fluid simulation . 'CG' Animators can break physical laws by using mathematical algorithms to cheat mass , force and gravity , and more. Fundamentally, computer-generated animation is a powerful tool which can improve the quality of animation by using the power of computing to unleash the animator's imagination. This is because Computer Generated Animation allows for things like onion skinning which allows 2D animators to see

666-492: A computer and an animation software. Some impressive animation can be achieved even with basic programs; however, the rendering can require much time on an ordinary home computer. Professional animators of movies, television and video games could make photorealistic animation with high detail. This level of quality for movie animation would take hundreds of years to create on a home computer. Instead, many powerful workstation computers are used; Silicon Graphics said in 1989 that

740-431: A computer animation called " Kitty " was created with BESM -4 by Nikolai Konstantinov, depicting a cat moving around. In 1971, a computer animation called "Metadata" was created, showing various shapes. An early step in the history of computer animation was the sequel to the 1973 film Westworld , a science-fiction film about a society in which robots live and work among humans. The sequel, Futureworld (1976), used

814-534: A human face and a hand that had originally appeared in the 1971 experimental short A Computer Animated Hand , created by University of Utah students Edwin Catmull and Fred Parke . 3-D computer graphics software began appearing for home computers in the late 1970s. The earliest known example is 3D Art Graphics , a set of 3-D computer graphics effects, written by Kazumasa Mitazawa and released in June 1978 for

888-477: A new similar image but advanced slightly in time (usually at a rate of 24, 25, or 30 frames/second). This technique is identical to how the illusion of movement is achieved with television and motion pictures . To trick the visual system into seeing a smoothly moving object, the pictures should be drawn at around 12 frames per second or faster (a frame is one complete image). With rates above 75 to 120 frames per second, no improvement in realism or smoothness

962-504: A process known as tweening . However, in 3D computer animation, this is done automatically, and is called interpolation . Finally, the animation is rendered and composited . Before becoming a final product, 3D computer animations only exist as a series of moving shapes and systems within 3d software, and must be rendered . This can happen as a separate process for animations developed for movies and short films, or it can be done in real-time when animated for videogames. After an animation

1036-509: A raster graphic alternative to animated GIF files that enables multi-level transparency not available in GIFs. Computer animation uses different techniques to produce animations. Most frequently, sophisticated mathematics is used to manipulate complex three-dimensional polygons , apply " textures ", lighting and other effects to the polygons and finally rendering the complete image. A sophisticated graphical user interface may be used to create

1110-404: A similar manner to those who use the commercial grade equipment. The realistic modeling of human facial features is both one of the most challenging and sought after elements in computer-generated imagery. Computer facial animation is a highly complex field where models typically include a very large number of animation variables. Historically speaking, the first SIGGRAPH tutorials on State of

1184-414: A simplified representation of a character's anatomy, which is analogous to a skeleton or stick figure . They are arranged into a default position known as a bind pose , or T-Pose. The position of each segment of the skeletal model is defined by animation variables, or Avars for short. In human and animal characters, many parts of the skeletal model correspond to the actual bones, but skeletal animation

1258-559: A way to improve performance of the game engine or for stylistic and gameplay concerns. By contrast, games using 3D computer graphics without such restrictions are said to use true 3D. Computer animation Computer animation is the process used for digitally generating moving images. The more general term computer-generated imagery (CGI) encompasses both still images and moving images , while computer animation only refers to moving images. Modern computer animation usually uses 3D computer graphics . Computer animation

1332-456: Is a mathematical representation of any three-dimensional object; a model is not technically a graphic until it is displayed. A model can be displayed visually as a two-dimensional image through a process called 3-D rendering , or it can be used in non-graphical computer simulations and calculations. With 3-D printing , models are rendered into an actual 3-D physical representation of themselves, with some limitations as to how accurately

1406-769: Is a career path which involves separate workflows, and different software and tools. The combination of all or some 3D computer animation disciplines is commonly referred to within the animation industry as the 3D animation pipeline. 2D computer graphics are still used for stylistic, low bandwidth, and faster real-time renderings . Computer animation is essentially a digital successor to stop motion techniques, but using 3D models, and traditional animation techniques using frame-by-frame animation of 2D illustrations. For 2D figure animations, separate objects (illustrations) and separate transparent layers are used with or without that virtual skeleton. In 2D computer animation, moving objects are often referred to as " sprites ." A sprite

1480-426: Is a class of 3-D computer graphics software used to produce 3-D models. Individual programs of this class are called modeling applications or modelers. 3-D modeling starts by describing 3 display models : Drawing Points, Drawing Lines and Drawing triangles and other Polygonal patches. 3-D modelers allow users to create and alter models via their 3-D mesh . Users can add, subtract, stretch and otherwise change

1554-422: Is a digital successor to stop motion and traditional animation . Instead of a physical model or illustration, a digital equivalent is manipulated frame-by-frame. Also, computer-generated animations allow a single graphic artist to produce such content without using actors, expensive set pieces, or props . To create the illusion of movement, an image is displayed on the computer monitor and repeatedly replaced by

1628-458: Is also used to animate other things, with facial features (though other methods for facial animation exist). The character "Woody" in Toy Story , for example, uses 712 Avars (212 in the face alone). The computer does not usually render the skeletal model directly (it is invisible), but it does use the skeletal model to compute the exact position and orientation of that certain character, which

1702-437: Is an image that has a location associated with it. The location of the sprite is changed slightly, between each displayed frame, to make the sprite appear to move. The following pseudocode makes a sprite move from left to right: Computer-assisted animation is usually classed as two-dimensional ( 2D ) animation and is also known as digital ink and paint. Drawings are either hand drawn (pencil to paper) or interactively drawn (on

1776-544: Is attended by thousands of computer professionals each year. Developers of computer games and 3D video cards strive to achieve the same visual quality on personal computers in real-time as is possible for CGI films and animation. With the rapid advancement of real-time rendering quality, artists began to use game engines to render non-interactive movies, which led to the art form Machinima . CGI short films have been produced as independent animation since 1976. Early examples of feature films incorporating CGI animation include

1850-517: Is eventually rendered into an image. Thus by changing the values of Avars over time, the animator creates motion by making the character move from frame to frame. There are several methods for generating the Avar values to obtain realistic motion. Traditionally, animators manipulate the Avars directly. Rather than set Avars for every frame, they usually set Avars at strategic points (frames) in time and let

1924-512: Is not always to emulate live action as closely as possible, so many animated films instead feature characters who are anthropomorphic animals, legendary creatures and characters, superheroes, or otherwise have non-realistic, cartoon-like proportions. Computer animation can also be tailored to mimic or substitute for other kinds of animation, like traditional stop-motion animation (as shown in Flushed Away or The Peanuts Movie ). Some of

1998-510: Is not composed solely of rendering). A workstation typically costs $ 2,000 to $ 16,000 with the more expensive stations being able to render much faster due to the more technologically advanced hardware that they contain. Professionals also use digital movie cameras , motion/ performance capture , bluescreens , film editing software , props, and other tools used for movie animation. Programs like Blender allow for people who can not afford expensive animation and rendering software to be able to work in

2072-407: Is perceivable due to the way the eye and the brain both process images. At rates below 12 frames per second, most people can detect jerkiness associated with the drawing of new images that detracts from the illusion of realistic movement. Conventional hand-drawn cartoon animation often uses 15 frames per second in order to save on the number of drawings needed, but this is usually accepted because of

2146-711: Is possible with traditional animation , while still retaining the stylistic elements of traditionally drawn characters or objects. Examples of films produced using computer-assisted animation are the rainbow sequence at the end of The Little Mermaid (the rest of the films listed use digital ink and paint in their entirety), The Rescuers Down Under , Beauty and the Beast , Aladdin , The Lion King , Pocahontas , The Hunchback of Notre Dame , Hercules , Mulan , Tarzan , We're Back! A Dinosaur's Story , Balto , Anastasia , Titan A.E. , The Prince of Egypt , The Road to El Dorado , Spirit: Stallion of

2220-426: Is recorded to a computer using video cameras and markers and that performance is then applied to the animated character. Each method has its advantages and as of 2007, games and films are using either or both of these methods in productions. Keyframe animation can produce motions that would be difficult or impossible to act out, while motion capture can reproduce the subtleties of a particular actor. For example, in

2294-595: Is rendered, it can be composited into a final product. For 3D models, attributes can describe any characteristic of the object that can be animated. This includes transformation (movement from one point to another), scaling, rotation, and more complex attributes like blend shape progression (morphing from one shape to another). Each attribute gets a channel on which keyframes can be set. These keyframes can be used in more complex ways such as animating in layers (combining multiple sets of key frame data), or keying control objects to deform or control other objects. For instance,

2368-452: Is required, but the types of characters required exceed what can be done throughout the conventional costuming. 3D computer animation combines 3D models of objects and programmed or hand "keyframed" movement. These models are constructed out of geometrical vertices, faces, and edges in a 3D coordinate system. Objects are sculpted much like real clay or plaster, working from general forms to specific details with various sculpting tools. Unless

2442-548: Is then used to in a two-level structure – the PAD-PEP mapping and the PEP-FAP translation model. Realism in computer animation can mean making each frame look photorealistic , in the sense that the scene is rendered to resemble a photograph or make the characters' animation believable and lifelike. Computer animation can also be realistic with or without the photorealistic rendering . One trend in computer animation has been

2516-485: Is to use procedural tools such as 4D noise . Noise is any algorithm that plots pseudo-random values within a dimensional space. 4D noise can be used to do things like move a swarm of bees around; the first three dimensions correspond to the position of the bees in space, and the fourth is used to change the bee's position over time. Noise can also be used as a cheap replacement for simulation . For example, smoke and clouds can be animated using noise. Node-based animation

2590-485: Is useful for animating organic and chaotic shapes. By using nodes, an animator can build up a complex set of animation rules that can be applied either to many objects at once, or one very complex object. A good example of this would be setting the movement of particles to match the beat of a song. There are many different disciplines of 3D animation, some of which include entirely separate artforms. For example, hair simulation for computer animated characters in and of itself

2664-1076: Is usually performed using 3-D computer graphics software or a 3-D graphics API . Altering the scene into a suitable form for rendering also involves 3-D projection , which displays a three-dimensional image in two dimensions. Although 3-D modeling and CAD software may perform 3-D rendering as well (e.g., Autodesk 3ds Max or Blender ), exclusive 3-D rendering software also exists (e.g., OTOY's Octane Rendering Engine , Maxon's Redshift) 3-D computer graphics software produces computer-generated imagery (CGI) through 3-D modeling and 3-D rendering or produces 3-D models for analytical, scientific and industrial purposes. There are many varieties of files supporting 3-D graphics, for example, Wavefront .obj files and .x DirectX files. Each file type generally tends to have its own unique data structure. Each file format can be accessed through their respective applications, such as DirectX files, and Quake . Alternatively, files can be accessed through third-party standalone programs, or via manual decompilation. 3-D modeling software

2738-610: The Apple II . 3-D computer graphics production workflow falls into three basic phases: The model describes the process of forming the shape of an object. The two most common sources of 3D models are those that an artist or engineer originates on the computer with some kind of 3D modeling tool , and models scanned into a computer from real-world objects (Polygonal Modeling, Patch Modeling and NURBS Modeling are some popular tools used in 3D modeling). Models can also be produced procedurally or via physical simulation . Basically,

2812-451: The B board, which contains the game itself. The relationship between the A and B board is very similar to that between a home video game console and cartridge . CP System II A and B boards are color-coded by region, and each board can only be used with its same-colored mate. The exception to this is that the blue and green boards can be used together. The B boards hold battery-backed memory containing decryption keys needed for

2886-431: The wire-frame model and 2-D computer raster graphics in the final rendered display. In computer graphics software, 2-D applications may use 3-D techniques to achieve effects such as lighting , and similarly, 3-D may use some 2-D rendering techniques. The objects in 3-D computer graphics are often referred to as 3-D models . Unlike the rendered image, a model's data is contained within a graphical data file. A 3-D model

2960-477: The 2006 film Pirates of the Caribbean: Dead Man's Chest , Bill Nighy provided the performance for the character Davy Jones . Even though Nighy does not appear in the movie himself, the movie benefited from his performance by recording the nuances of his body language, posture, facial expressions, etc. Thus motion capture is appropriate in situations where believable, realistic behavior and action

3034-424: The 3D wire-frame imagery, which featured a computer-animated hand and face both created by University of Utah graduates Edwin Catmull and Fred Parke . This imagery originally appeared in their student film A Computer Animated Hand , which they completed in 1972. Developments in CGI technologies are reported each year at SIGGRAPH , an annual conference on computer graphics and interactive techniques that

3108-644: The Cimarron and Sinbad: Legend of the Seven Seas . Early digital computer animation was developed at Bell Telephone Laboratories in the 1960s by Edward E. Zajac, Frank W. Sinden, Kenneth C. Knowlton, and A. Michael Noll. Other digital animation was also practiced at the Lawrence Livermore National Laboratory . In 1967, a computer animation named "Hummingbird" was created by Charles Csuri and James Shaffer. In 1968,

3182-467: The animation industry's needs typically caused graphical innovations in workstations. Graphics workstation computers use two to four processors, and they are a lot more powerful than an actual home computer and are specialized for rendering. Many workstations (known as a " render farm " ) are networked together to effectively act as a giant computer, resulting in a computer-animated movie that can be completed in about one to five years (however, this process

3256-535: The art in Facial Animation in 1989 and 1990 proved to be a turning point in the field by bringing together and consolidating multiple research elements and sparked interest among a number of researchers. The Facial Action Coding System (with 46 "action units", "lip bite" or "squint"), which had been developed in 1976, became a popular basis for many systems. As early as 2001, MPEG-4 included 68 Face Animation Parameters (FAPs) for lips, jaws, etc., and

3330-563: The board would just simply die, even if used legally it would not play after a finite amount of time unless a fee was paid to Capcom to replace it. Due to the heavy encryption, it was believed for a long time that CP System II emulation was next to impossible. However, in January 2001, the CPS-2 Shock group was able to obtain unencrypted program data by hacking into the hardware, which they distributed as XOR difference tables to produce

3404-433: The computer interpolate or tween between them in a process called keyframing . Keyframing puts control in the hands of the animator and has roots in hand-drawn traditional animation . In contrast, a newer method called motion capture makes use of live action footage. When computer animation is driven by motion capture, a real performer acts out the scene as if they were the character to be animated. Their motion

3478-438: The computer) using different assisting appliances and are positioned into specific software packages. Within the software package, the creator places drawings into different key frames which fundamentally create an outline of the most important movements. The computer then fills in the "in-between frames", a process commonly known as Tweening . Computer-assisted animation employs new technologies to produce content faster than

3552-586: The effort to create human characters that look and move with the highest degree of realism. A possible outcome when attempting to make pleasing, realistic human characters is the uncanny valley , the concept where the human audience (up to a point) tends to have an increasingly negative, emotional response as a human replica looks and acts more and more human. Films that have attempted photorealistic human characters, such as The Polar Express , Beowulf , and A Christmas Carol have been criticized as "disconcerting" and "creepy". The goal of computer animation

3626-636: The field has made significant progress since then and the use of facial microexpression has increased. In some cases, an affective space , the PAD emotional state model , can be used to assign specific emotions to the faces of avatars . In this approach, the PAD model is used as a high level emotional space and the lower level space is the MPEG-4 Facial Animation Parameters (FAP). A mid-level Partial Expression Parameters (PEP) space

3700-493: The field of special effects ) skyrocketed during the modern era of U.S. animation . Films like Avatar (2009) and The Jungle Book (2016) use CGI for the majority of the movie runtime, but still incorporate human actors into the mix. Computer animation in this era has achieved photorealism, to the point that computer-animated films such as The Lion King (2019) are able to be marketed as if they were live-action. In most 3D computer animation systems, an animator creates

3774-465: The final form. Some graphic art software includes filters that can be applied to 2D vector graphics or 2D raster graphics on transparent layers. Visual artists may also copy or visualize 3D effects and manually render photo-realistic effects without the use of filters. Some video games use 2.5D graphics, involving restricted projections of three-dimensional environments, such as isometric graphics or virtual cameras with fixed angles , either as

3848-402: The final game released for the hardware. Capcom ended most of the technical support for the hardware and its games on March 31, 2015. Battery replacements ended on February 28, 2019, ending all official support of the CP System II hardware and software. 3D graphics 3D computer graphics , sometimes called CGI , 3-D-CGI or three-dimensional computer graphics , are graphics that use

3922-426: The flow of their work all at once, and interpolation which allows 3D animators to automate the process of inbetweening . For 3D computer animations, objects (models) are built on the computer monitor (modeled) and 3D figures are rigged with a virtual skeleton . Then the limbs, eyes, mouth, clothes, etc. of the figure are moved by the animator on key frames . Normally, the differences between key frames are drawn in

3996-457: The games to run. As time passes, these batteries lose their charge and the games stop functioning, because the CPU cannot execute any code without the decryption keys. This is generally referred to as a "suicide battery". It is possible to bypass the original battery and swap it out with a new one in-circuit, but this must be done before the original falls below 2V or the keys will be lost. Consequently,

4070-410: The gap by giving amateurs access to professional animations as clip art . The oldest (most backward compatible) web-based animations are in the animated GIF format, which can be uploaded and seen on the web easily. However, the raster graphics format of GIF animations slows the download and frame rate, especially with larger screen sizes. The growing demand for higher quality web-based animations

4144-497: The help of video references and accurate meteorological facts. For the 2005 remake of King Kong , actor Andy Serkis was used to help designers pinpoint the gorilla's prime location in the shots and used his expressions to model "human" characteristics onto the creature. Serkis had earlier provided the voice and performance for Gollum in J. R. R. Tolkien 's The Lord of the Rings trilogy. Computer animation can be created with

4218-526: The live-action films Star Trek II: The Wrath of Khan and Tron (both 1982), and the Japanese anime film Golgo 13: The Professional (1983). VeggieTales is the first American fully 3D computer-animated series sold directly (made in 1993); its success inspired other animation series, such as ReBoot (1994) and Transformers: Beast Wars (1996) to adopt a fully computer-generated style. The first full-length computer-animated television series

4292-761: The long-standing basic principles of animation , like squash and stretch , call for movement that is not strictly realistic, and such principles still see widespread application in computer animation. The popularity of websites that allow members to upload their own movies for others to view has created a growing community of independent and amateur computer animators. With utilities and programs often included free with modern operating systems , many users can make their own animated movies and shorts. Several free and open-source animation software applications exist as well. The ease at which these animations can be distributed has attracted professional animation talent also. Companies such as PowToon and Vyond attempt to bridge

4366-404: The mesh to their desire. Models can be viewed from a variety of angles, usually simultaneously. Models can be rotated and the view can be zoomed in and out. 3-D modelers can export their models to files , which can then be imported into other applications as long as the metadata are compatible. Many modelers allow importers and exporters to be plugged-in , so they can read and write data in

4440-539: The mid-level, or Autodesk Combustion , Digital Fusion , Shake at the high-end. Match moving software is commonly used to match live video with computer-generated video, keeping the two in sync as the camera moves. Use of real-time computer graphics engines to create a cinematic production is called machinima . Not all computer graphics that appear 3D are based on a wireframe model . 2D computer graphics with 3D photorealistic effects are often achieved without wire-frame modeling and are sometimes indistinguishable in

4514-541: The more complex vector graphic animations had a slower frame rate due to complex rendering compared to some of the raster graphic alternatives. Many of the GIF and Flash animations were already converted to digital video formats, which were compatible with mobile devices and reduced file sizes via video compression technology. However, compatibility was still problematic as some of the video formats such as Apple's QuickTime and Microsoft Silverlight required plugins. YouTube

4588-402: The native formats of other applications. Most 3-D modelers contain a number of related features, such as ray tracers and other rendering alternatives and texture mapping facilities. Some also contain features that support or allow animation of models. Some may be able to generate full-motion video of a series of rendered scenes (i.e. animation ). Computer aided design software may employ

4662-499: The physical model can match the virtual model. William Fetter was credited with coining the term computer graphics in 1961 to describe his work at Boeing . An early example of interactive 3-D computer graphics was explored in 1963 by the Sketchpad program at Massachusetts Institute of Technology's Lincoln Laboratory . One of the first displays of computer animation was Futureworld (1976), which included an animation of

4736-628: The render engine how to treat light when it hits the surface. Textures are used to give the material color using a color or albedo map, or give the surface features using a bump map or normal map . It can be also used to deform the model itself using a displacement map . Rendering converts a model into an image either by simulating light transport to get photo-realistic images, or by applying an art style as in non-photorealistic rendering . The two basic operations in realistic rendering are transport (how much light gets from one place to another) and scattering (how surfaces interact with light). This step

4810-401: The result is two-dimensional, without visual depth . More often, 3-D graphics are being displayed on 3-D displays , like in virtual reality systems. 3-D graphics stand in contrast to 2-D computer graphics which typically use completely different methods and formats for creation and rendering. 3-D computer graphics rely on many of the same algorithms as 2-D computer vector graphics in

4884-432: The same fundamental 3-D modeling techniques that 3-D modeling software use but their goal differs. They are used in computer-aided engineering , computer-aided manufacturing , Finite element analysis , product lifecycle management , 3D printing and computer-aided architectural design . After producing a video, studios then edit or composite the video using programs such as Adobe Premiere Pro or Final Cut Pro at

4958-547: The situation, Capcom took the CP System hardware (with QSound ) with minimal changes and employed encryption on the program ROMs to prevent software piracy . Due to the encryption, the system was never bootlegged until unencrypted program data became available. The CP System II consists of two separate parts; the A board, which connects to the JAMMA harness and contains components common between all CP System II games, and

5032-452: The spline curves relative to the keyframes. Using interpolation allows 3D animators to dynamically change animations without having to redo all the in-between animation. This also allows the creation of complex movements such as ellipses with only a few keyframes. Lastly, interpolation allows the animator to change the framerate, timing, and even scale of the movements at any point in the animation process. Another way to automate 3D animation

5106-864: The stylized nature of cartoons. To produce more realistic imagery, computer animation demands higher frame rates. Films seen in theaters in the United States run at 24 frames per second, which is sufficient to create the illusion of continuous movement. For high resolution, adapters are used. Computer-generated animation is an umbrella term for three-dimensional ( 3D ) animation, and 2D computer animation. These also include subcategories like asset driven , hybrid, and digital drawn animation. Creators animate using code or software instead of pencil-to-paper drawings. There are many techniques and disciplines in computer generated animation, some of which are digital representations of traditional animation - such as key frame animation - and some of which are only possible with

5180-405: The temporal description of an object (i.e., how it moves and deforms over time. Popular methods include keyframing , inverse kinematics , and motion-capture ). These techniques are often used in combination. As with animation, physical simulation also specifies motion. Materials and textures are properties that the render engine uses to render the model. One can give the model materials to tell

5254-479: The unencrypted data from the original ROM images , making emulation possible, as well as restoring cartridges that had been erased because of the suicide system. In January 2007, the encryption method was fully reverse-engineered by Andreas Naive ( Archived 2013-07-02 at the Wayback Machine ) and Nicola Salmoria . It has been determined that the encryption employs two four-round Feistel ciphers with

5328-520: Was ReBoot , which debuted in September 1994; the series followed the adventures of characters who lived inside a computer.
