Un calculateur (1) affecte automatiquement ou par l'intermédiaire d'un utilisateur (5) un type d'objet (T) respectif à des objets segmentés (7) dans un jeu de données volumétriques (6). Le calculateur (1) affecte une règle d'application (A, Aj) à chaque objet segmenté (7) et il présente au moins les objets segmentés (7) sous la forme d'une image (B) par le biais d'un appareil de visualisation (8) à l'utilisateur (5). Dans le cadre de la présentation du jeu de données volumétriques (6), le calculateur (1) traite les objets (7) segmentés en fonction des règles d'application (A, Aj) affectées aux objets (7). Avant l'affectation des règles d'application (A, Aj) aux objets segmentés (7), le calculateur (1) reçoit une instruction de sélection (C2) de l'utilisateur (5) et, sur la base de cette instruction de sélection (C2), il sélectionne une règle de groupe (Gi). Les règles de groupe (Gi) contiennent chacune plusieurs règles d'application (Aj) à utiliser pour des objets (7) d'un type d'objet (T) donné. Pour les objets segmentés (7) contenus dans le jeu de données volumétriques (6), le calculateur (1) détermine automatiquement, en fonction du type d'objet (T) affecté à chaque objet segmenté (7), la règle d'application (Aj) correspondante contenue dans la règle de groupe sélectionnée et il l'affecte aux objets (7) concernés.
