Holograms in concert
Martin Scorses said recently that holograms are the future of 3D. He is maybe not that far off the reality as we cpuld have seen yesterday at the HatsuneMiku concert in Singapore during the Anime Festival Asia (11-13 Novembrer 2011).
It starts off like a regular concert, with the lights dimmed and the band slowly taking their place in the background. Then the lead vocalist gets the crowd going with some cheery pop music. Except the lead vocalist isn't really human. She's a CGI character, and she's projected live on the stage in 3-D. True, it's not the full parallax holography that our own researchers are working on. That doesn't change the fact that the 3D effect still looks far more advanced than anything we've come up with so far. That's not the only thing astounding about this concert. See, that little CGI girl? Her name is Hatsune Miku. "She" is actually a vocaloid, a program that synthesizes human speech to the point that it can sing.
An amateur video from the 11/11/11 concert is available here under on YouTube (in 2D).
You may want to read a 2010 paper from Tom's Guide explaining how the holograms are created.
A similar concert will take place in Tokyo, Japan on January 28, 2012. Check Miku's web site for details (it is in Japanese however...).
