1. Computer-implemented method for tessellating a three-dimensional modeled object parameterized for tessellation, comprising the steps of: providing 2D meshes associated to geometrical data of a boundary representation of the modeled object, the boundary representation comprising the geometrical data including parametric surfaces and topological data including a set of faces each defined as a portion of the 2D domain of a respective parametric surface; and determining 3D meshes by evaluating the position of vertices of the 2D meshes on the respective parametric surfaces.
