Cafu Engine

The Cafu Engine is a game engine developed by Carsten Fuchs. It is portable across platforms and runs on Windows and Linux, with plans to be adapted to OS X. The engine's source code is freely available under the MIT Licence.

Features
A factory building in the Cafu Engine

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.[1]

  • 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.

A terrain that is part of a map is edited

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 GNU GPLv3 license since December 2009, while offering the option of a commercial license upon agreement with Carsten Fuchs Software.[2] On June 19, 2016, the engine changed its open source license from GPLv3 to the MIT License.[3]

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.[4] 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:

The Cafu Engine has been reviewed and presented in these publications:

gollark: <@!309787486278909952> Troubling news. I found a package in the AUR and not the void repos.
gollark: There is frequently tons of stuff going on at once here.
gollark: ABR has approximately that capability built in. I can upgrade it.
gollark: Also, I accidentally inspired heavpoot to make a tool to scan ngrok for Minecraft servers and may have doomed us all.
gollark: I personally enjoy writing SQL directly.
