TECNOLOGIA
SCHEDA TECNICA
Questo documentario interattivo è stato realizzato fondendo insieme vari linguaggi e tecnologie.
L’ambiente di sviluppo è costruito con tecnologia HTML5 WebGL pensata per la computer grafica 3D sul WEB. Ringraziamo il progetto opensource three.js per il prezioso aiuto in termini di solidità e leggibilità del codice.
Le riprese video volumetriche degli intervistati e degli oggetti sono state effettuate utilizzando il DepthKit, un software capace di combinare il video RGB con le informazioni di profondità registrate dai sensori della Microsoft Kinect.
I modelli delle Ville Medicee e delle Statue che vanno a comporre le infografiche sono stati realizzati attraverso al modellazione 3d, la fotogrammetria e le scansioni laser. Le riprese aeree e la fotogrammetria area sono state effettuate tramite droni.
La texture del Sound Design nasce dalla rielaborazione in chiave elettronica di alcuni brani riprodotti dall’ensemble L’Homme Armé. La realizzazione dei soundscape è avvenuta tramite sintesi analogica, Max MSP e codifiche in ambix per spazializzare i suoni in 3D.
