X3D 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).
Irrlicht is an open-source game engine written in C++. It is cross-platform, officially running on Windows, macOS, Linux and Windows CE and due to its open nature ports to other systems are available, including FreeBSD, Xbox, PlayStation Portable, Symbian, iPhone, AmigaOS 4, Sailfish OS via a Qt/QML wrapper, and Google Native Client.
In scientific visualization and computer graphics, volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field.
In computer graphics, a shader is a computer program that calculates the appropriate levels of light, darkness, and color during the rendering of a 3D scene—a process known as shading. Shaders have evolved to perform a variety of specialized functions in computer graphics special effects and video post-processing, as well as general-purpose computing on graphics processing units.
A lightmap is a data structure used in lightmapping, a form of surface caching in which the brightness of surfaces in a virtual scene is pre-calculated and stored in texture maps for later use. Lightmaps are most commonly applied to static objects in applications that use real-time 3D computer graphics, such as video games, in order to provide lighting effects such as global illumination at a relatively low computational cost.
A physics engine is computer software that provides an approximate simulation of certain physical systems, such as rigid body dynamics, soft body dynamics, and fluid dynamics, of use in the domains of computer graphics, video games and film (CGI). Their main uses are in video games, in which case the simulations are in real-time. The term is sometimes used more generally to describe any software system for simulating physical phenomena, such as high-performance scientific simulation.
COLLADA is an interchange file format for interactive 3D applications. It is managed by the nonprofit technology consortium, the Khronos Group, and has been adopted by ISO as a publicly available specification, ISO/PAS 17506.
High-dynamic-range rendering, also known as high-dynamic-range lighting, is the rendering of computer graphics scenes by using lighting calculations done in high dynamic range (HDR). This allows preservation of details that may be lost due to limiting contrast ratios. Video games and computer-generated movies and special effects benefit from this as it creates more realistic scenes than with more simplistic lighting models.
The Blender Game Engine was a free and open-source 3D production suite used for making real-time interactive content. It was previously embedded within Blender, but support for it was dropped in 2019, with the release of Blender 2.8. The game engine was written from scratch in C++ as a mostly independent component, and includes support for features such as Python scripting and OpenAL 3D sound.
Panda3D is a game engine that includes graphics, audio, I/O, collision detection, and other abilities relevant to the creation of 3D games. Panda3D is free, open-source software under the revised BSD license.
Messiah is a 3D animation and rendering application developed by pmG Worldwide. It runs on the Win32 and Win64 platforms. It is marketed to run on Mac OS X and Linux via Wine. Messiah's fourth version, messiah:studio was released April 2009 and version 5.5b as messiah:animate was released November 2006. messiahStudio6 was released in April 2013. Messiah seems no longer maintained since 2013 (abandoned).
Away3D is an open-source platform for developing interactive 3D graphics for video games and applications, in Adobe Flash or HTML5. The platform consists of a 3D world editor, a 3D graphics engine, a 3D physics engine and a compressed 3D model file format (AWD).
CloudCompare is a 3D point cloud processing software. It can also handle triangular meshes and calibrated images.
In computer graphics, tessellation is the dividing of datasets of polygons presenting objects in a scene into suitable structures for rendering. Especially for real-time rendering, data is tessellated into triangles, for example in OpenGL 4.0 and Direct3D 11.
Orx is an open-source, portable, lightweight, plug-in-based, data-driven and easy to use 2D-oriented game engine written in C.
This is a glossary of terms relating to computer graphics.
Art of Illusion is a free software, and open source software package for making 3D graphics.
Babylon.js is a JavaScript library and 3D engine for displaying real time 3D graphics in a web browser via HTML5. The source code is available on GitHub and distributed under the Apache License 2.0.
