OpenGL (Open Graphics Library) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.

Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. Originally, the names of these APIs all began with "Direct", such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth. The name DirectX was coined as a shorthand term for all of these APIs (the X standing in for the particular API names) and soon became the name of the collection. When Microsoft later set out to develop a gaming console, the X was used as the basis of the name Xbox to indi

Real-time motion capture software or technology are often—but not always—used to capture movement. The digital trend originated in Japan in the mid-2010s, and has become an international online phenomenon in the 2020s. A majority of VTubers are English- and Japanese-speaking YouTubers or live streamers who use avatar designs. By 2020, there were more than 10,000 active VTubers. Although the term is an allusion to the video platform YouTu

The DualShock (originally Dual Shock, trademarked as DUALSHOCK or DUAL SHOCK, with the PlayStation 5 version as DualSense) is a line of gamepads developed by Sony Interactive Entertainment for the PlayStation family of video game consoles. It is named for vibration-feedback and analog controls. Introduced in November 1997, it was initially marketed as a secondary peripheral for the first PlayStation console. The console's bundle was updated to include DualShock, and phase out the original PlayStation controller and the Dual Analog Controller. The DualShock is the best-selling gamepad of all ti

VRML (Virtual Reality Modeling Language, pronounced vermal or by its initials, originally—before 1995—known as the Virtual Reality Markup Language) is a standard file format for representing 3-dimensional (3D) interactive vector graphics, designed particularly with the World Wide Web in mind. It has been superseded by X3D.

WebGL (short for Web Graphics Library) is a JavaScript API for rendering interactive 2D and 3D graphics within any compatible web browser without the use of plug-ins. WebGL is fully integrated with other web standards, allowing GPU-accelerated usage of physics, image processing, and effects in the HTML canvas. WebGL elements can be mixed with other HTML elements and composited with other parts of the page or page background.

Vulkan is a cross-platform API and open standard for 3D graphics and computing. It was intended to address the shortcomings of OpenGL, and allow developers more control over the GPU. It is designed to support a wide variety of GPUs, CPUs and operating systems, and modern multi-core CPUs also.

CryEngine (stylized as CRYENGINE) is a game engine designed by the German game developer Crytek. It has been used in all of their titles with the initial version being used in Far Cry, and continues to be updated to support new consoles and hardware for their games. It has also been used for many third-party games under Crytek's licensing scheme, including Sniper: Ghost Warrior 2 and SNOW. Warhorse Studios uses a modified version of the engine for their medieval RPG Kingdom Come: Deliverance. Ubisoft maintains an in-house, heavily modified version of CryEngine from the original Far Cry called

X3D (Extensible 3D) is a set of royalty-free ISO/IEC standards for declaratively representing 3D computer graphics. X3D includes multiple graphics file formats, programming-language API definitions, and run-time specifications for both delivery and integration of interactive network-capable 3D data. X3D version 4.0 has been approved by Web3D Consortium, and is under final review by ISO/IEC as a revised International Standard (IS).

visual presentation of a 3-dimensional or physical object used in 3D computer graphics

Shading refers to the depiction of depth perception in 3D models (within the field of 3D computer graphics) or illustrations (in visual art) by varying the level of darkness. Shading tries to approximate local behavior of light on the object's surface and is not to be confused with techniques of adding shadows, such as shadow mapping or shadow volumes, which fall under global behavior of light.

visionOS is an extended reality operating system derived primarily from iPadOS and its core frameworks (including UIKit, SwiftUI, ARKit and RealityKit), and MR-specific frameworks for foveated rendering and real-time interaction. It was developed by Apple exclusively for its Apple Vision Pro mixed reality headset. It was unveiled on June 5, 2023, at Apple's WWDC23 event alongside the reveal of the Apple Vision Pro. The software released on February 2, 2024, shipping with the Apple Vision Pro.
