A large pseudo 3D display measuring 14x14x10 ft was built that used the pyramid Pepper's ghost to create the illusion of a floating 3D model. The Pepper's ghost was combined with laser projectors and anaglyph imaging to create more realistic 3D projections. Adding laser projectors worked well at removing the "ghostly", transparent characteristics of the projection often associated with the Pepper's ghost. The laser projectors were unable to display detailed images or textures and were limited to wireframes. A comparison of video and laser projectors found that only the laser projectors were capable of achieving good quality binocular disparity for the anaglyph images due to the high perceptual brightness of the laser images. A generalized framework for designing large 3D displays in public settings was proposed.
