3D-animated starships are superior to holograms in that they can be viewed from any direction.
Scientists at Brigham Young University (BYU) have created tiny 3D animations out of light. The animations pay homage to Star Trek and Star Wars with tiny versions of the USS Enterprise and a Klingon battle cruiser launching photon torpedoes, as well as miniature green and red light sabers with actual luminous beams. The animations are part of the scientists' ongoing "Princess Leia project"—so dubbed because it was partly inspired by the iconic moment in Star Wars Episode IV: A New Hope when R2D2 projects a recorded 3D image of Leia delivering a message to Obi-Wan Kenobi. The researchers described the latest advances on their so-called screenless volumetric display technologies in a recent paper published in the journal Scientific Reports.
"What you're seeing in the scenes we create is real; there is nothing computer generated about them," said co-author Dan Smalley, a professor of electrical engineering at BYU. "This is not like the movies, where the lightsabers or the photon torpedoes never really existed in physical space. These are real, and if you look at them from any angle, you will see them existing in that space."
