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.[2] In 2019, one of the project's main developers described it as "effectively dead and has been for a good number of years".[3]
Crystal Space is programmed in object oriented C++. It is very modularly built with a number of more or less independent plugins. The client programs use the plugins, such as the OpenGL 3D renderer, by registering them via Crystal Space's Shared Class Facility (SCF).
Crystal Space has modules for 2D and 3D graphics, sound, collision detection and physics through ODE and Bullet.
The engine was for instance used for the OpenOutcast and PlaneShift projects.[4] It was the Project of the Month on SourceForge in February 2003.[5]
