We have put into practical form one of Edwin Land's early inventions, the stereoscopic Vectograph image. We have reinterpreted the concept to produce digital 3-D hardcopy conveniently from both photographic and digital 3-D records. Digital 3-D images may be produced directly by digital cameras, by computers and workstations, and by various instrumental outputs or they may be acquired by scanning and digitizing photographic image pairs. Digital 3-D polarizing images are printed conveniently with an ink-jet printer. To produce full-color 3-D hardcopy on standard ink-jet printers we have formulated special inks and substrates. Our technique unites two very significant growing technologies: ink-jet printing and 3-D imaging.
