Three Dimensional Television : An Investigation Concerning Programmable Parallax Barriers
Stereoscopic or three dimensional display of images is a logical step in the evolution of electronic display systems. We see the world stereoscopically so it is only natural that representations of this experience should provide an equally rich visual sensation. There have been countless attempts …
