  • Patent number: 5673376
    Abstract: A system and method that generates computer graphic images using anti-aliasing rendering to create sets of offset images each of a lower resolution than the resolution desired. The anti-aliasing rendering is performed using offset weights that effectively cause a graphic model to be rendered at different rendering points for each low resolution image which are offset between low resolution images. The lower resolution offset images are then interlaced or combined to produce the desired high resolution image.

  • Patent number: 5543964
    Abstract: An apparatus and method of creating depth images with different depth image scenes being projected at different viewer orientations. At each of the orientations a different perspective series is provided to the viewer. To provide the different depth scenes at the different orientations, different depth content image slices of different depth content scenes are interleaved behind lenticules of a lenticular faceplate. The interleaving of different depth content scenes on an imaging substrate is accomplished by writing to a print file depth images of the different depth content scenes in successive positions prior to driving the printer with the print file contents to record on the substrate. The substrate is then attached to the lenticular faceplate.
