Stereoscopic displays allow observers to perceive depth effects and enable them to visualize information with ever-increasing complexity in three-dimensional (3D) space. The proliferation of 3D displays has been driven mainly by the tremendous potential of virtual reality and augmented reality (VR/AR) for a wide spectrum of application areas such as scientific visualization, engineering design, training and education, and entertainment. Rapid developments in 3D graphics capabilities on personal computers have further expedited the popularity of stereoscopic display techniques.
