Sur la base de t\u00e9raoctets de donn\u00e9es scientifiques, un groupe de recherche de l'EPFL a d\u00e9velopp\u00e9 un logiciel appel\u00e9 VIRUP, qui permet de visualiser l'univers en temps r\u00e9el pour la RV. <\/span><\/h3>\n

La galaxie en VR ? Ceux qui le souhaitent peuvent d\u00e9sormais explorer avec des lunettes VR - mais aussi sur leur ordinateur de bureau - une repr\u00e9sentation de l'univers que nous connaissons, bas\u00e9e sur d'immenses quantit\u00e9s de donn\u00e9es r\u00e9elles collect\u00e9es dans le cadre de diff\u00e9rents projets scientifiques. Le logiciel s'appelle VIRUP (The Virtual Reality Universe Project) et a \u00e9t\u00e9 d\u00e9velopp\u00e9 par un groupe de recherche en Suisse de l'\u00c9cole polytechnique f\u00e9d\u00e9rale de Lausanne (EPFL). Elle reproduit en temps r\u00e9el la vue de l'univers depuis la Terre jusqu'\u00e0 des groupes entiers de galaxies, en passant par notre syst\u00e8me solaire. La technique repose sur plusieurs t\u00e9raoctets de donn\u00e9es provenant entre autres de la mission Gaia de l'ESA. VIRUP est disponible en tant qu'application open source et en version b\u00eata pour Windows et Linux.<\/p>\n

Des donn\u00e9es r\u00e9elles comme base de visualisation<\/span><\/h3>\n

Pour la sortie du logiciel, VIRUP peut d\u00e9sormais visualiser les donn\u00e9es de plus de huit bases de donn\u00e9es, explique l'\u00e9quipe.<\/p>\n

Pour vivre pleinement l'exp\u00e9rience immersive en 3D et avec une vue panoramique, il faut porter des lunettes VR, mais le logiciel a \u00e9t\u00e9 d\u00e9velopp\u00e9 de mani\u00e8re \u00e0 prendre en charge d'autres \u00e9crans, dont une coupole, comme on en trouve dans les plan\u00e9tariums. Il est toutefois possible de s'en faire une id\u00e9e sur un PC normal, ce qui n\u00e9cessite, outre le fichier d'installation, une base de donn\u00e9es de plus de 11 gigaoctets. Un guide d'installation pr\u00e9cis<\/a> a \u00e9t\u00e9 mis en ligne par l'\u00e9quipe.<\/p>\n

<\/figure>\n

Avec ce projet, l'\u00e9quipe veut montrer l'impact durable de la pr\u00e9sentation des donn\u00e9es sur leur compr\u00e9hension. On peut ainsi se d\u00e9placer \u00e0 travers la carte la plus d\u00e9taill\u00e9e du cosmos sans quitter le confort de ses quatre murs, estime l'astrophysicien Jean-Paul Kneib : \"C'est la possibilit\u00e9 de voyager \u00e0 travers l'espace et le temps pour d\u00e9couvrir l'univers\".<\/p>\n
