L'invention concerne un procédé de génération d'une image 2D d'une surface 3D (2) sur une surface visible (8) d'un cône de vision (12) qui s'élargit depuis une position de vision (14) vers la surface 3D (2), au moins un emplacement de marqueur (20a,b) étant affecté à la surface 3D (2). Selon l'invention, une cote de profondeur est associée à chaque emplacement d'image de la surface visible (8), un champ de marqueur est généré et placé dans l'image 2D pour au moins l'un des emplacements de marqueur qui se trouvent dans le cône de vision (12), après le placement sans masquage des champs de marqueur, ceux-ci sont déposés dans l'image 2D avec une image projetée de la surface 3D (2) sur la surface visible (8). In a method for producing a 2D image (18) of a 3D surface (2) on a viewing area (8) of a vision cone (12) which extends from a viewing position (14) to the 3D surface (2), wherein at least one marker location (20a,b) is assigned to the 3D surface (2), assigned to each image location (24) of the viewing area (8) is a depth dimension (T), which is correlated to the respective distance (A) between the viewing area (8) and the 3D surface (2) along a respective straight line (26) from the viewing position (14) through the image location (24) to the 3D surface (2), for at least one of the marker locations (20a,b) located within the vision cone (12), a marker field (28a,b) is produced in the 2D image (18), wherein the marker field (28a,b) in the 2D image (18) is placed as closely as possible to the image location (24a,b) of the marker location (20a,b), with the additional condition that all image locations (24) of the marker field (28a,b) have depth dimensions (T) which are greater than the depth dimension (Ta,b) of the image location (24a,b) of the marker location (20a,b), after placement of the marker fields (28a,b) a projection image (10) of the 3D surface (2) onto the viewing area (8) is placed therebehind in the 2D image (18).
