3D computer graphics in the context of "Subsurface scattering"

In 3D computer graphics, 3D modeling is the process of developing a mathematical coordinate-based representation of a surface of an object (inanimate or living) in three dimensions via specialized software by manipulating edges, vertices, and polygons in a simulated 3D space.

Three-dimensional (3D) models represent a physical body using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc. Being a collection of data (points and other information), 3D models can be created manually, algorithmically (procedural modeling), or by scanning. Their surfaces may be further defined with texture mapping.

Augmented reality (AR), also known as mixed reality (MR), is a technology that overlays real-time 3D-rendered computer graphics onto a portion of the real world through a display, such as a handheld device or head-mounted display. This experience is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, compared to virtual reality, which aims to completely replace the user's real-world environment with a simulated one. Augmented reality is typically visual, but can span multiple sensory modalities, including auditory, haptic, and somatosensory.

The primary value of augmented reality is the manner in which components of a digital world blend into a person's perception of the real world, through the integration of immersive sensations, which are perceived as real in the user's environment. The earliest functional AR systems that provided immersive mixed reality experiences for users were invented in the early 1990s, starting with the Virtual Fixtures system developed at the U.S. Air Force's Armstrong Laboratory in 1992. Commercial augmented reality experiences were first introduced in entertainment and gaming businesses. Subsequently, augmented reality applications have spanned industries such as education, communications, medicine, and entertainment.

A personal computer game, or abbreviated PC game, also known as a computer game, is a video game played on a personal computer (PC). The term PC game has been popularly used since the 1990s referring specifically to games on "Wintel" (Microsoft Windows software/Intel hardware) which has dominated the computer industry since.

Mainframe and minicomputer games are a precursor to personal computer games. Home computer games became popular following the video game crash of 1983. In the 1990s, PC games lost mass market traction to console games on the fifth generation such as the Sega Saturn, Nintendo 64 and PlayStation. They are enjoying a resurgence in popularity since the mid-2000s through digital distribution on online service providers. Personal computers as well as general computer software are considered synonymous with IBM PC compatible systems; while mobile devices – smartphones and tablets, such as those running on Android or iOS platforms – are also PCs in the general sense as opposed to console or arcade machine. Historically, it also included games on systems from Apple Computer, Atari Corporation, Commodore International and others. Microsoft Windows utilizing Direct3D become the most popular operating system for PC games in the 2000s. Games utilizing 3D graphics generally require a form of graphics processing unit, and PC games have been a major influencing factor for the development and marketing of graphics cards. Emulators are able to play games developed for other platforms. The demoscene originated from computer game cracking.

Blender is a free and open-source 3D computer graphics software tool set that runs on Windows, macOS, Linux, BSD, Haiku, and IRIX. It is used for creating animated films, visual effects, art, 3D-printed models, motion graphics, interactive 3D applications, and virtual reality. It is also used in creating models for video games.

Blender was used to produce the Academy Award-winning film Flow (2024).

This is a list of models and meshes commonly used in 3D computer graphics for testing and demonstrating rendering algorithms and visual effects. Their use is important for comparing results, similar to the way standard test images are used in image processing.

Computer-generated imagery (CGI) is a specific-technology or application of computer graphics for creating or improving images in art, printed media, simulators, videos and video games. These images are either static (i.e. still images) or dynamic (i.e. moving images). CGI both refers to 2D computer graphics and (more frequently) 3D computer graphics with the purpose of designing characters, virtual worlds, or scenes and special effects (in films, television programs, commercials, etc.). The application of CGI for creating/improving animations is called computer animation (or CGI animation).

The 1990s (often referred and shortened to as "the '90s" or "the Nineties") was the decade that began on 1 January 1990, and ended on 31 December 1999. Known as the "post-Cold War decade", the 1990s were culturally imagined as the period from the Revolutions of 1989 until the September 11 attacks in 2001. The dissolution of the Soviet Union marked the end of Russia's status as a superpower, the end of a multipolar world, and the rise of anti-Western sentiment. China was still recovering from a politically and economically turbulent period. This allowed the US to emerge as the world's sole superpower, creating relative peace and prosperity for many western countries. During this decade, the world population grew from 5.3 to 6.1 billion.

The decade saw greater attention to multiculturalism and advance of alternative media. Public education about safe sex curbed HIV in developed countries. Generation X bonded over musical tastes. Humor in television and film was marked by ironic self-references mixed with popular culture references. Alternative music movements like grunge, reggaeton, Eurodance, K-pop, and hip-hop, became popular, aided by the rise in satellite and cable television, and the internet. New music genres such as drum and bass, post-rock, happy hardcore, denpa, and trance emerged. Video game popularity exploded due to the development of CD-ROM supported 3D computer graphics on platforms such as Sony PlayStation, Nintendo 64, and PCs.

Computer animation 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 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.
