According to Machinima.org:
Machinima (muh-sheen-eh-mah) is filmmaking within a real-time, 3D virtual environment, often using 3D video-game technologies.It is one thing to go out into the world and record. It is a totally different experience having to create the world first.
In an expanded definition, it is the convergence of filmmaking, animation and game development. Machinima is real-world filmmaking techniques applied within an interactive virtual space where characters and events can be either controlled by humans, scripts or artificial intelligence.
