Declarative camera control for automatic cinematography

摘要: Animations generated by interactive 3D computer graphics applications are typically portrayed either from a particular character's point of view or small set strategically-placed viewpoints. By ignoring camera placement, such fail to realize important storytelling capabilities that have been explored cinematographers for many years. In this paper, we describe several the principles cinematography and show how they can be formalized into declarative language, called Declarative Camera Control Language (OCCL). We application OCCL within context simple video game argue represents cinematic knowledge at same level abstraction as expert directors encoding 16 idioms film textbook. These produce compelling animations, demonstrated on accompanying videotape.
