Parallel image generation for a 3D display

Two viewing models for an experimental three-dimensional display are presented. Two alternative projections were tried. These are parallel oblique and perspective oblique, and they place different requirements on the 3-D display hardware. The parallel oblique projections may produce a jagged effect when P is small but will correctly maintain the horizontal parallax effect for a range of distances between screen and viewer. With the aid of parallel processing the time required to change the 3-D image will be comparable with the time taken to alter the image on a conventional display
