3D video, despite never really succeeding as a consumer-level product, still has some success today in movie theaters, as more and more big-budget movies are released in 3D to try and squeeze a few more dollars out of patrons. Some movie studios even tried to turn 2D movies to 3D to reproduce classic movies in 3D effect and bring the 3D versions to theatre, such as Titanic. But there are drawbacks to 3D movies: cinematically, the polarizing 3D glasses also result in darker, less vibrant perception of the movie. Based on these, glasses-free 3D movie viewing technology has been required.
Though glasses-free 3D viewing technology has already available, it relies on screens with massive resolution requirements. Therefore it’s impractical to recreate the big-screen movie theatre experience. However, the glass-free 3D movie experience might shortly come into theatre since researchers have developed 3D movie screens that don't require 3D glasses.
