LinRadiant is a level (map) editor for FPS games that use id Software's engines (Quake 1/2/3). It is a derivative of NetRadiant with an improved build system. It is very easy to build, even for people with little experience in software development. It has built-in support for the following games: Darkplaces, Wolfenstein:ET, Nexuiz, OpenArena, Quake, Quake 2, Quake2world, Quake III Arena, Q3MIN, Tremulous, Warsow, and Xonotic. The package contains a lot of useful documentation (mapping tutorials, technical documents, etc.) that are automatically installed and can be accessed from within the editor.
wavelet2d is a set of C++ libraries for 1D/2D (decimated and stationary) discrete wavelet transforms. This implementation is geared towards students and others who want to implement simple DWT routines as part of their bigger projects. In order to speed up the implementation, these libraries are implemented using FFT routines from the FFTW3 library. Example code and documentation are available. The libraries are made available in the form of Win32 MSVC++ DLLs, Win32 MinGW DLLs and static libraries, and Linux shared and static libraries.
Grand Unified Builder (GUB) is a mini source-based distribution and packaging system. It cross-compiles several packages with their dependencies and assembles them into a single installation package. It currently supports GNU/Linux, FreeBSD, Mac OS X, and Microsoft Windows installation packages. All packages are fully relocatable and can be installed with user privileges. Plain Python classes are used to describe package build specifics. For reasonably well behaved packages, individual build specifications can stay very simple by extending the generic build specification classes. It was originally developed for turnkey building of all LilyPond binary installers.
openDarkEngine is a from-scratch rewrite of the famous Dark Engine originally written by Looking Glass Studios. The engine was used in the Thief 1, Thief Gold, Thief 2, and System Shock 2 games. This rewrite is targeted at newer machines and should improve compatibility and give the games (and all the fan made material) a never ending life. It should also allow manipulation of the original data files.
