2Pac is Back Performing Live

Tupac rose from the dead and stole the show at Coachella, performing alongside Snoop Dogg and Dr. Dre. “What the f- is up, Coachella?” a hologram of the rapper, who died in 1996, asked the audience. The walking-and-talking projection is estimated to have cost about $400,000 and took four months to complete. It was a team effort by Dr. Dre, James Cameron’s Digital Domain, and two imaging companies. But how did the digital Tupac work? Although it is being called a hologram, it was actually a 2-D projection. Just before Tupac’s appearance, a 30-foot-by-13-foot transparent screen descended across the stage. The images of Tupac were projected from above onto a reflective surface, which then reflected them onto the giant screen. The screen was angled in such a way that the audience could watch Tupac performing but could not see the screen itself. Dr. Dre has yet to say how he got Tupac’s voice to sing the songs and say the word “Coachella.”

The video contains explicit lyrics, this picture explain how hologram works.

Holograms are 3-D images that have been projected and captured on a 2-D surface. The most common ones are found on things like credit cards, designed to foil potential forgers. but with the right tools, it’s possible to create your own holograms at home: all you need is a laser (red is best), lenses to spread out the beam, mirrors to direct the beam to the desired locations, a beam splitter, and holographic film, which has a finer grain than regular film and thus can record light at much greater resolution.
