![]() ![]() Theoretically, a T-spline surface can represent any arbitrarily shaped model no matter how complicated its topology structure is. ![]() in 2003 to conquer the limitations of NURBS in practical engineering applications.Īs a generalization of NURBS, T-splines introduce T-junctions and extraordinary points into its control mesh. Thus, T-splines were firstly proposed by Sederberg et al. Nevertheless, in modern industry, complex engineering models comprised of multiple NURBS patches are always not watertight because of the existence of gaps and overlaps along the interfaces of trimmed NURBS surfaces. With a series of excellent mathematical and algorithmic properties, non-uniform rational B-splines (NURBS) has been widely used in the field of computer aided geometric design for representing curves and surfaces. ![]()
