A method of presenting a 3D image is described in which a scene is captured by at least two spatially separated video cameras to provide signals representing at least two viewpoints. The signals are conveyed to a viewing apparatus by standard television broadcast or video recording techniques with frames of alternate viewpoints interleaved to produce time sequential frame displays. The viewing apparatus is observed by the viewer through eyepieces which are rendered transparent and obscure in synchronism with the frame rate. A further method of presenting a 3D virtual graphics image is also described. The 3D images may be an event in which one or more participants, such as sports persons, are predefined as objects. Video data defining each object may be created and transmitted prior to the event, and at least one object may be defined as a series of salient points and offsets therefrom. During the event, sequential frames may be transmitted each of which contains data, and which may be coded and embedded digital data, defining the positional co-ordinates of said salient points, from which a complete virtual model can be reconstructed in real time at a remote site. |
