"Aurora di Venere" is a performance for theatre where a group of dancers interact with digital entities projected on two screens located at the background and at the front (semi-transparent) of the theatre's stand. The dancers play with the images of the artificial individuals which move on the screen following own personality. The digital entities are represented with 3D living shape. They can reproduce and are equipped with a neural network for self-learning and decision taking. Reflecting the movements of the dancers, the digital beings dance approaching the dancers or escape from they.

The background are realized by virtual 3D worlds retro-projected on the back screen. The public can move the objects and perspective of the virtual backgrounds trough radio-mouse and play with the dancers.

The story grows in intensity during its development and the artificial beings escape from the screens invading the public and the theatre ceiling. They search for the public movements and produce 3D sounds travelling in the theatre. At the end the whole internal pseudo-spherical surface of the theatre is invaded by digital beings.

Three O2 (Silicon Graphics workstations) have been used for the alife server and 3D graphics. Six PC for the virtual backgrounds and public interaction. Three infrared cameras and IR lamps have been utilized for the dancers and public tracking (interaction with the artificial beings). Six high power video-projectors have been utilized to cover the whole theatre internal surface utilized as a projection sphere. Finally a PC and a 3D sound spatializer machine have been utilized for the 3D sounds effects. We would like to thank the Nergal s.rl. company for the product IMEASY used for the 3D sound rendering.
