The first images to be displayed on the autostereoscopic displays were the images by Isaksen et al. Some of the images such as the big flower appeared to have a focal depth where only the frontmost flower is in focus. The background is heavily blurred so seeing the parallax was difficult. Other images such as the toys scene worked sufficiently well. Unfortunately, the results cannot be readily captured on paper. The second series of images are of a teapot. These images are generated from scratch starting with the glut teapot call. Various degrees of FOV are rendered. Figures 9 and 10 are teapots using 10 and 40 degree FOV respectively. The horizontal jaggy lines are an artifact of pixel accuracy when compositing multiple hexagonal images. One can smooth the image, but in practice these seems are not noticeable to an observer through the autostereoscopic display.

Figure 10: An autosterescopic image using a 40 degree FOV.

Finally, a 360 degree rotation animation of the teapot was also made. The goal is to show an animated autostereoscopic display. However, the parallax is not that evident since the rotation is hiding the disparity that an observer can normally detect by moving his head back and forth. The movie took approximately 14 hours to produce. A couple nights were also spent getting a variant of the unstructured lumigraph viewer to sample a reparameterized light field. However a bug in moving the virtual viewpoint prevented such an endevour.
