OE-Cake, OE-CAKE! or OE Cake is a 2D fluid physics sandbox which was used to demonstrate the Octave Engine fluid physics simulator created by Prometech Software Inc.. It was one of the first engines with the ability to realistically process water and other materials in real-time. In the program, which acts as a physics-based paint program, users can insert objects and see them interact under the laws of physics. It has advanced fluid simulation, and support for gases, rigid objects, elastic reactions, friction, weight, pressure, textured particles, copy-and-paste, transparency, foreground and background images, and easy file sharing.

OE-Cake was eventually superseded by the no-longer available PhysiCafe^[1] program, which was a web-app demonstration of the same engine.

The name OE-Cake comes from the name of the engine and the word "cake" loosely means "draw" in Japanese; its name therefore means "OctaveEngine Draw".

File format

OE-Cake uses the .OEC file format for saving scenes made using the program. In OE-Cake version 1.1b, the file format was changed. Version 1.0b files can be opened with version 1.1.2b. Version 1.1.2b files cannot be properly opened in version 1.0b.

OE-Cake files are stored in plaintext format, which makes them easy to share, small in size, and allows copying and pasting of particles and modified behaviour of the engine.

OE-Cake supports changing of the Parameters that define the physics and other behaviours in the game. To change these parameters, open an OE-Cake save with a text editor, scroll to the bottom, and change the values of a variable to change the behaviour of the game.
