Abstract : This thesis deals with geometric modeling of complex 3D free-form shapes. In the context of the Art3D project (ACI Masses de Données), we have investigated two research directions related to the representation of digitized objects, with a flexibility goal: dynamic surface reconstruction and multirepresentation modeling. In the first part of the thesis, we introduce a flexible combinatorial approach to surface reconstruction that makes it possible to directly generate a simplified triangulated surface from a dense input point set. The reconstructed surface can be next locally refined or coarsened in a dynamic fashion. The second part presents a hybrid modeling framework for creating complex shapes from scanned models or simple primitives. We have developed an extended CSG tree that mixes implicit surfaces, polygonal meshes, and point set models in a coherent fashion
