Title (EN) METHODS OF CONSTRUCTING A PRINTABLE 3D MODEL, AND RELATED DEVICES AND COMPUTER PROGRAM PRODUCTS
(FR) PROCÉDÉS DE CONSTRUCTION D'UN MODÈLE 3D IMPRIMABLE, ET DISPOSITIFS ET PRODUITS PROGRAMMES INFORMATIQUES ASSOCIÉS
Abstract:
(EN) Methods of constructing a printable three-dimensional (3D) model are provided. A method of constructing a printable 3D model includes constructing a ray-cast mesh representation of an object by using ray-casting on a preliminary digital 3D model of the object. Moreover, the method includes converting the preliminary digital 3D model of the object into the printable 3D model, of the object by adding, to the preliminary digital 3D model of the object, an interior surface that is based on the ray-cast mesh representation. Related devices and computer program products are also provided.
(FR) L'invention concerne des procédés de construction d'un modèle tridimensionnel (3D) imprimable. Un procédé de construction d'un modèle 3D imprimable comprend la construction d'une représentation en maillage par lancer de rayon d'un objet à l'aide d'un lancer de rayon sur un modèle 3D numérique préliminaire de l'objet. De plus, le procédé comprend la conversion du modèle 3D numérique préliminaire de l'objet dans le modèle 3D imprimable, de l'objet par ajout, au modèle 3D numérique préliminaire de l'objet, d'une surface intérieure qui est basée sur la représentation en maillage par lancer de rayon. L'invention concerne également des dispositifs et des produits programmes informatiques associés.
