Dans cet article nous étudions des mots multidimensionnels engendrés par des points fixes de substitutions, et obtenus en projetant les points entiers sur la demi-droite brisée correspondante. Nous montrons que pour une grande classe de substitutions le mot correspondant est la restriction d’une fonction linéaire modulo 1 et qu’il est possible de décider si le mot résultant remplit l’espace. La preuve utilise des réseaux et le système de numération abstrait associé à la substitution.

In this paper we study multi-dimensional words generated by fixed points of substitutions by projecting the integer points on the corresponding broken halfline. We show for a large class of substitutions that the resulting word is the restriction of a linear function modulo 1 and that it can be decided whether the resulting word is space filling or not. The proof uses lattices and the abstract number system associated with the substitution.
