Abstract: It is proposed a computer-implemented method for parameterizing a three-dimensional modeled object for tessellation. The method comprising the steps of providing a boundary representation of the modeled object, the boundary representation comprising 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; determining 2D meshes each fitting a respective face; and associating the 2D meshes to the geometrical data of the boundary representation. Such a solution improves the tessellation of a 3D modeled object.

Abstract: It is proposed a computer-implemented method for tessellating a three-dimensional modeled object parameterized for tessellation. The method comprises 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.Such a solution improves the tessellation of a 3D modeled object.
