ABSTRACT:
A method and apparatus for recording and playback of multidimensional walkthrough narratives. A three dimensional modeling language is used to automatically create a simple three-dimensional environment using pre-existing electronic documents. A first user, or author may navigate throughout the three-dimensional environment while at the same time recording the path taken and any accompanying audio. In one of two playback modes, a second user can be shown a “walkthrough” of the three-dimensional scene corresponding to the path taken by the author. In the other playback mode, a second user is free to navigate the three-dimensional world while the author's path is displayed.
