Cafu Engine

License
  
GPL or optionally proprietary

The Cafu Engine is a game engine developed by Carsten Fuchs. It is portable across platforms and currently runs under Windows and Linux, with plans to be adapted to OS X. The engine's source code is freely available under the GPL, but can be obtained under a proprietary license.

Features

In general, Cafu is built with a modular architecture so as to avoid program constructs and libraries that are specific to any given operating system, compiler, CPU or graphics processor. To that end, the Cafu source code compiles both as 32- as well as native 64-bit software.

  • The Cafu Engine abstracts out its handling of materials and instead uses rendering objects, thus enabling users to work with different graphics systems such as OpenGL or DirectX.
  • Physics are handled by an internal system to deal with human movement, and everything else uses Bullet, a free physics engine; Cafu synchronizes the two systems
  • Lighting is handled by radiosity computations, or dynamic lighting through stencil shadow volumes
  • Like the material system, sound is abstracted out and can support various implementations such as OpenAL and FMOD
  • Inherently designed for online games with multiple players over a computer network
  • Game server that centrally manages the game state and events, as well as a client that is used by players

    • Scripting and editing

    In order to not have to fix details in difficult to modify program code, the Cafu Engine employs scripting based on the programming language Lua in many parts of the program.

    Cafu includes a graphical editor, CaWE, that contains all the tools required to create new levels: a Map Editor, GUI Editor, Font-Wizard, Material Browser and Model Editor.

    Licensing

    The Cafu Engine's source code has been freely available under the GPL since December 2009. It is also available under a commercial license (dual licensing) so that producers are not necessarily bound to the GPL.

    Reviews and applications

    The Cafu Engine has been used by the United States Air Force's Research Labs for Human Effectiveness in a study about the visual working memory of pilots. It has also been used in multiple studies and research projects that simulate artificial lighting in urban environments and examine how that lighting is perceived by humans and influences the nocturnal orientation of pedestrians and motorists:
