Jake2 is a pure Java port of the Quake2 game engine. It features OpenGL rendering using jogl and OpenAL sound using joal. To use the Jake2 engine, you need either the data files from the original game or from the demo version. An online installation of the demo levels is possible. A lwjgl driver is included as an alternative to the jogl/joal combination. Single player and multiplayer modes are working. Jake2 comes close to the performance of the original engine written in C.
UProxy is a proxy for UDP protocols. UProxy was initially designed to allow users to play Unreal Tournament matches over the Internet on computers sharing a dial up connection. It could also be used by any client-server application that uses the UDP protocol and doesn't require clients to bind a fixed port. UProxy should run under Windows, Linux, or any OS which supports BSD sockets.
BFM (Brutal Filemanager) is a mixture between a filemanager and a 3D shoot-'em-up game. In fact, you can't really manage the files yet, just shoot them up. Be carefull when using BFM! Some weapons, such as the shotgun, have spread. So files you didn't really aim at might get ... wasted. Start BFM with the '-s' for safemode and your files shall stay unhurt. It is written in Java and uses the Java3D API.
L3D is a 3D library for developing OpenGL applications under Linux. The library has a main display loop, and call-back functions similar to those in GLUT. It has a graphical console for output of information. The goal of this project is a library which is small and hopefully scalable.
