A fast, powerful and adaptable GUI solution
Crazy Eddie's GUI (CEGUI) system is a graphical user interface C++ library. It was designed particularly for the needs of videogames, but the library is usable for non-game tasks, such as any other type of applications (rendering/visualisation/virtual reality) and tools. It is designed for user flexibility in look-and-feel, as well as being adaptable to the user's choice in tools and operating systems. Established in 2003, CEGUI sees continual, active development and remains one of the most powerful and most popular options for developers requiring an adaptable and efficient GUI solution. CEGUI is fully supported by the developers that created - and continue to develop - the library, and who are accessible via the project's dedicated internet forums and IRC channel. For more information, more screenshots and for news, check out out our homepage: http://cegui.org.uk The repository is now at bitbucket (including our issue/bug tracker): https://bitbucket.org/cegui
