Abstract

A method for real-time video communication. Specifically, one embodiment of the present invention discloses a method of video conferencing that captures a plurality of real-time video streams of a local participant from a plurality of sample viewpoints. From the plurality of video streams, a new view synthesis technique can be applied to generate a video image stream in real-time of the local participant rendered from a second location of a second participant with respect to a first location of the local participant in a coordinate space of a virtual environment. A change in either of the locations leads to the modifying of the video image stream, thereby enabling real-time video communication from the local participant to the second participant.
