Abstract: Generating 3D representations of a scene represented by a first video stream captured by video cameras. Identifying a transition between cameras, retrieving parameters of a first set of viewing configurations, providing 3D video representations representing the scene at several sets of viewing configurations different from the first set of viewing configurations, and generating an integrated video stream enabling 3D display of the scene by integration of at least two video streams having respective sets of viewing configurations, which are mutually different. Another provided process is for synthesizing an image of an object from a first image, captured by a certain camera at a first viewing configuration. Assigning a 3D model to a portion of a segmented object, calculating a modified image of the portion of the object from a viewing configuration different from the first viewing configuration, and embedding the modified image in a frame for stereoscopy.
