In this paper a method for creating geometrical models of tree-like anatomical structures is described. This method is basically interactive and thus it takes advantage of the user's expertise to define highly-structured models even when using nonhomogeneous data sets. First, tubular cavities are reconstructed sequentially; then, junctions between these cavities are provided in such a way that resulting models are continuously shaped (we characterize this property by the G1-continuity (i.e., a tangent plane can be defined at any point on the surface).
