Abstract

Communication in a three-dimensional virtual environment generated by a computer is achieved by automatically applying rules of cinematography typically used for motion pictures. A camera view specification is produced (40) from interpreted cinematographic events (38). A real time camera controller, called the virtual cinematographic application module (VC) (50), is used in vertual reality and other interactive applications to improve upon the fixed point-of-view shots or ceiling mounted cameras. VC (50) is used in intelligent agent user interfaces to allow users to see themselves with an agent at camera positions that appear natural.
