A game engine is a software framework primarily designed for the development of video games and generally includes relevant libraries and support programs such as a level editor. The "engine" terminology is akin to the term "software engine" used more widely in the software industry.
Crystal Space is an unmaintained framework for developing 3D applications written in C++ by Jorrit Tyberghein and others. The first public release was on August 26, 1997. It is typically used as a game engine but the framework is more general and can be used for any kind of 3D visualization. It is very portable and runs on Microsoft Windows, Linux, UNIX, and Mac OS X. It is also free and open-source software, licensed under the GNU LGPL-2.0-or-later, and was SourceForge.net's Project of the Month for February 2003. In 2019, one of the project's main developers described it as "effectively dead and has been for a good number of years".
OpenAL is a cross-platform audio application programming interface (API). It is designed for efficient rendering of multichannel three-dimensional positional audio. Its API style and conventions deliberately resemble those of OpenGL. OpenAL is an environmental 3D audio library, which can add realism to a game by simulating attenuation, the Doppler effect, and material densities.
Torque Game Engine, or TGE, is an open-source cross-platform 3D computer game engine, developed by GarageGames and actively maintained under the current versions Torque 3D as well as Torque 2D. It was originally developed by Dynamix for the 2001 first-person shooter Tribes 2. In September 2012, GarageGames released Torque 3D as open-source software under the MIT License.
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.
The Open Dynamics Engine (ODE) is a physics engine written in C/C++. Its two main components are a rigid body dynamics simulation engine and a collision detection engine. It is free software licensed both under the BSD license and the LGPL.
PhysX is an open-source realtime physics engine middleware SDK developed by Nvidia as a part of Nvidia GameWorks software suite.
Full Tilt! Pinball is a pinball video game developed by Cinematronics and published by Maxis in 1995. It features pre-rendered 3D graphics and three tables: Space Cadet, Skullduggery, and Dragon's Keep. On each table, side displays show the players' scores, ball numbers, player numbers, various other information, and a table-specific image.
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.
Delta3d is an open source software gaming/simulation engine API. Delta3d is managed and supported by Caper Holdings LLC. Previously the Modeling, Virtual Environments, and Simulation (MOVES) Institute at the Naval Postgraduate School in Monterey, California managed and supported delta3d. Alion Science has also been a major contributor to enhancements and features.
An open-source video game, or simply an open-source game, is a video game whose source code is open-source. They are often freely distributable and sometimes cross-platform compatible.
The Physics Abstraction Layer (PAL) is an open-source cross-platform physical simulation API abstraction system. It is similar to a physics engine wrapper, however it is far more flexible providing extended abilities. PAL is free software, released under the BSD license.
Penumbra: Overture is the first in a series of episodic survival horror games developed by Frictional Games. The game follows a physicist named Philip who travels to Greenland after his mother's death and is forced to explore an abandoned mine. Penumbra: Overture received average reception from critics.
Scythe is a free software physics modeling program. It allows the merging of physics and graphics content in one package. It provides native support for modeling the rigid body physics for the Newton Game Dynamics, the Open Dynamics Engine and PhysX engine. The Physics Abstraction Layer also provides support for the Scythe format.
Frictional Games AB is a Swedish independent video game developer based in Malmö, founded in January 2007 by Thomas Grip and Jens Nilsson. The company specialises in the development of survival horror games with very little or no combat gameplay mechanics. It is best known for its games Amnesia: The Dark Descent and Soma.
Future Pinball ("FP") is a freeware 3D pinball editing and gaming application for Microsoft Windows. It is similar to Visual Pinball ("VP") and other modern pinball simulation applications. Just as with VP's partnership with Visual PinMAME, FP uses partner applications to emulate original pinball ROM code. In FP's case, the end results of ROM code are simulated by Better Arcade Mode ("BAM") and tools such as "Pinball Browser" and dot-matrix display software plugins. Core FP development was discontinued in 2010, but resumed in 2013 via BAM. BAM features many new developments, such as enhanced physics, optics, and virtual reality support.
Amnesia: The Dark Descent is a survival horror adventure video game by Frictional Games, released in 2010 for Microsoft Windows, Mac OS X and Linux operating systems, in 2016 for the PlayStation 4 platform and in 2018 for the Xbox One. The game features a protagonist named Daniel exploring a dark and foreboding castle called Brennenburg, while trying to maintain his sanity by avoiding monsters and unsettling events. The game was critically well-received, earning two awards from the Independent Games Festival and numerous positive reviews.
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).
