This session will highlight requirements and the variety of digital 3D production. Phil Streather will talk about the experience he gathered with different stereoscopic film projects. About four million visitors a year will see his recent short film in a purpose-designed theatre in Merlin Entertainments London Eye. They will be taken to a 4D world: a 3D film combined with physical effects. One of the biggest challenges was the work on the helicopter to show a breathtaking flight over the city. Despite its short length, the movie required a creative cast of more than 100 people. The result is definitely more than an adrenaline-pumping, bone-rattling 4D experience.
