Conceptos Stereoscopic 3-D Multiperspective 3-D Multiperspective 3-D differs from the stereoscopic 3-D now common in movie theaters in that the depicted objects disclose new perspectives as the viewer moves about them, just as real objects would. Pepper’s ghost technique uses a partially reflective surface to mix a reflection with the scene beyond. John Henry Pepper demonstrated the technique in the 1860s with it being used to overlay visual elements (often a figure – ‘ghost’) onto a physical set or stage.

3D arrays (Founded 1996) UPV/EHU10Alex Garcia-Alonso
3D arrays The projection volume is composed of a physically deep stack of 20 electrically-switchable liquid crystal scattering shutters. At any instant in time 19 of scattering shutters are transparent and only one is in a white scattering state. We switch a single shutter into the scattering state and project onto it the appropriate image slice corresponding to its physical depth. Since each image slice is stopped in the projection volume at the correct depth, the DepthCube produces a 3D image that is truly deep and can be perceived without the need of any glasses.
