  • Patent number: 6525732
    Abstract: A three-dimensional object may be imaged from several viewpoints distributed about the object, and the image obtained at each viewpoint may be stored in conjunction with the viewpoint's coordinates about the object. The object's image can then be transmitted for display over a client-server computer network, and the user may issue commands to manipulate the object, so as to very accurately simulate manipulation of the actual three-dimensional object. The client computer may display the object's image from one of the viewpoints. If the user then wishes to manipulate the object, the user will issue a command to the server to index from the coordinates of the first viewpoint to the coordinates of some adjacent viewpoint(s). The images of the adjacent viewpoints will then be displayed in a sequence corresponding to the order in which the coordinates of the viewpoints are indexed.
