The first public release was on August 26, 1997.<ref name=firstrelease /> 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.<ref name="potm">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In 2019, one of the project's main developers described it as "effectively dead and has been for a good number of years".<ref name="unmaintained">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Engine designEdit
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).
FeaturesEdit
Crystal Space has modules for 2D and 3D graphics, sound, collision detection and physics through ODE and Bullet.
- Graphics:
- OpenGL rendering
- Supports hardware acceleration from all major card vendors
- Allows use of shaders
- Library of common shaders like normal mapping, parallax mapping and hardware skinning
- Supports software rendering with limited features
- Mesh objects:
- Plugin-based mesh system
- Triangle-based meshes with frame and bone animation support
- Collision detection and dynamics:
Reception and usageEdit
The engine was, for instance, used for the OpenOutcast and PlaneShift projects.<ref>Crystal Space 1.2 Released by Corvus Elrod on The Escapist (8 October 2007)</ref> It was the Project of the Month on SourceForge in February 2003.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
