Abstract

L'invention concerne un procédé mis en œuvre par ordinateur de génération d'un modèle 3D de simulation dentaire, consistant à lire un fichier décrivant la surface d'un objet 3D présentant un certain volume ; générer une grille de voxels englobant l'objet 3D, la grille de voxels contenant une pluralité de voxels ; identifier un sous-ensemble de voxels de la pluralité de voxels qui sont situés à l'intérieur du volume de l'objet 3D ; générer une surface triangulée, la surface triangulée englobant le sous-ensemble de voxels et délimitant la surface extérieure du modèle 3D ; attribuer une valeur de densité à chaque voxel du sous-ensemble de voxels, le sous-ensemble de voxels délimitant le volume solide du modèle 3D.
