|Over more than a century of motion picture presentations there have been periods when 3D has emerged, and each time interest has faded away. The latest 3D wave goes back to the advent of digital technology for cinemas. Digital Cinema Initiatives (DCI) was formed in 2002 and delivered its first DCI Specification in 2005, when Doremi was well ahead with the necessary technology for a DCI-compliant player. It was very soon clear that digital cinema technology could sweep aside many of the shortcomings of the film-based 3D presentations, and so open the door to a new 3D era. The digital medium is far more accurate than film could ever be. With no film weave, sparkles, scratches, frame hops or wear, digital cinema delivers, steady, clean, sharp, in-sync presentations that are as good on the 200th run as the first. This is the perfect medium to provide a comfortable and exciting viewing experience for stereoscopic 3D movies.
