La mod\u00e9lisation 3D consiste \u00e0 cr\u00e9er des objets<\/mark><\/strong>, des environnements <\/mark><\/strong>ou des produits <\/mark><\/strong>en trois dimensions \u00e0 partir de logiciels sp\u00e9cialis\u00e9s. Elle permet de transformer une id\u00e9e, un croquis ou un concept en repr\u00e9sentation num\u00e9rique d\u00e9taill\u00e9e et r\u00e9aliste.<\/p>\n\n\n\n

      C’est ici que l’on ajoute tous les d\u00e9tails, souvent via le sculpting num\u00e9rique (ZBrush) ou la mod\u00e9lisation polygonale avanc\u00e9e.
