The technology is based on the system integration between 3D programs developed Italy by 3Dlivelive, in the United States and in Canada which, using new generation graphics cards, send out two stereo signals (left and right) to a 3D cinema encoder. The encoder codifies the signals and sends them on to a cinema 3D projector – or two aligned projectors – with polarized lenses for passive projections (non- active cinema glasses). Both front and back projections are possible depending on the conditions on site.
This system also allows the rendering of basic effects and hard-disk animations with “real-time” projections following the action on-stage or the music by means of a manual control-system. So the virtual set can be modified during the rehearsal and, in case of emergency, even during the show. This technology is suitable to several different events, ranging from classical music concerts to operas, ballets, pop or rock concerts as well as presentations of buildings, conventions or interactive art exhibitions. The use of computer graphics This technology yields the best results if supported by stage drawings, photos or films created using computer graphics.
The aim of all this is to ensure that, from the audience’s point of view, the set is constantly present on the positive and on the negative parallax, i.e. in the background and “outside” the screen, just like in computer graphics productions for the cinema. After all, the spectators are willing to wear glasses only if they think this is the only way to enjoy substantially better scenery.
