<p>Three-dimensional scenes are portrayed from different viewpoints by morphing two-dimensional images. Various key views of a scene are stored, along with offset maps that identify the correspondence of pixels in adjacent stored images. When an intermediate view of the scene is to be presented, one ore more stored views are interpolated through a morphing technique. Since the key views and their offset data are pre-stored, the morphing and presentation of new views can be carried out at interactive rates. By providing the ability to quickly compute many closely spaced views, the disclosed morphing technique also facilitates the rapid computation of soft shadows and motion blur in images.</p> |
