Avatar: The technology behind Cameron's 3-D spectacle

Today is running a film that has been positioned in advance as expressly provided technical spectacle: Avatar. James Cameron has long been known as a champion of 3D technology, the development of relevant cameras with Vince Pace (who here to an audio - listen to interview) is also promoted himself, and hopes to present film is now the ultimate stereoscopic Showcase. But there is not just that the film obviously mainly of computer generated images, it shows virtual worlds and creatures. The latter were created using expensive motion capture techniques - in itself nothing new, but arrived at the recording a feature is used. A virtual camera made it possible for Cameron, when shooting in a virtual preview of this environment and the characters rendered in real time to be able to. The movements of the actors in motion capture suits, to be tracked with a variety of infrared cameras, and also the location of the preview monitor in the room is so recognized. From these data and existing CG templates are then calculated with a software called SimulCam a preview of the final scene in reduced resolution. Will the move change the preview monitor to match the perspective and the view. With a curse he could not yet operate any mouse camera, said Cameron) in this www.wired.com/magazine/2009/11/ff_avatar_movie/ (Wired article, such a camera movements would look always artificially generated.

The complete description of the world will Na'vi later in book form (Pandorapedia) - Merchandising halt seem somehow have the huge production costs are indeed taken again ... With a few exceptions, the film comes off very well in the reviews, with The 3D effects and the technical implementation will be discussed remarkably little - in fact a compliment, but says that they work ... Who wants to see the film in 3D, can at heise a list of all the converted consult cinemas, although there are according to this page, unfortunately, very few cinemas, showing the film, both in 3D as well as in the English original version. By the way, apparently it came yesterday at the preview screenings in various cinemas in downtime. Due to a lack of security, the key lying on the servers other uses of DRM system have not been released ...
