Abstract

We present a system dedicated to the real-time production of multimedia products and TV shows involving multiple virtual actors and presenters. This system, named VHD (virtual human director), may also be used for character animation on high-level systems and interaction with Web-based applications. The user can create virtual stories by directing all actions in real time. It is similar to a movie producer directing actors during filming but with more control given to the director in the sense that everything is decided and controlled by the same person. To make this complicated task possible, in a useable way, we based the interaction on the high-level control of the virtual actor

Virtual cinematography

Virtual cinematography is the set of cinematographic techniques performed in a computer graphics environment. It includes a wide variety of subjects like photographing real objects, often with stereo or multi-camera setup, for the purpose of recreating them as three-dimensional objects and algorithms for the automated creation of real and simulated camera angles. Virtual cinematography can be used to shoot scenes from otherwise impossible camera angles, create the photography of animated films, and manipulate the appearance of computer-generated effects.

Real-time computing

Real-time computing (RTC) is the computer science term for hardware and software systems subject to a "real-time constraint", for example from event to system response. Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines". Real-time responses are often understood to be in the order of milliseconds, and sometimes microseconds. A system not specified as operating in real time cannot usually guarantee a response within any timeframe, although typical or expected response times may be given.

Virtual world

A virtual world (also called a virtual space) is a computer-simulated environment which may be populated by many users who can create a personal avatar, and simultaneously and independently explore the virtual world, participate in its activities and communicate with others. These avatars can be textual, graphical representations, or live video avatars with auditory and touch sensations. Virtual worlds are closely related to mirror worlds.
