Camera control for shot selection in machinima generated animation

The development of computer graphics–rendering technology is rapidly increasing—the next-gen game can present 3D images that are closer to reality and can be run in real time. This allows the emergence of a new technique called “machinima,” derived from the words machine and cinema, to make real-time animation movies in a virtual environment. Machinima filmmaking requires a cinematography rule to produce a good animation. A behavior tree is used to select the camera shot according to the cinematography rule using shot idiom such as close-up, back-shot, shoulder-shot, etc. The system allows the camera to decide the proper shot based on events and actions happening in the virtual scene.
