View transition sequence of tracking a person between camera A and adjacent camera B in an office hallway surveillance scenario (see video). The guided 3D navigation enables simple first-person video observation while ensuring a good visual flow for spatial context. Our method dynamically embeds and blends video canvases in a 3D VE which consists of characteristic model landmarks and perspective lines.
