Sederberg, Jianmin Zheng, Tom Lyche, David Cardon, G. ^ Reconsideration of T-spline data models and their exchanges using STEP.Transitioning from NURBS to T-splines (67-minute video).was founded in 2004 to commercialize the technologies and acquired by Autodesk, Inc. patent office granted patent number 7,274,364 for technologies related to T-Splines. T-splines were initially defined in 2003. Pixar's variant of the subdivision surfaces has the advantage of edge weights. Subdivision surfaces are widely adopted in the animation industry. Polygon meshes can represent exact intersections but lack the shape quality required in industrial design. However, none of T-splines, subdivision surfaces, or NURBS surfaces can always accurately represent the (exact, algebraic) intersection of two surfaces within the same surface representation.

Subdivision surfaces, as well as T-spline and NURBS surfaces with the addition of geometrically continuous constructions, can represent everywhere-smooth surfaces of any connectivity and topology, such as holes, branches, and handles. Subdivision surfaces, NURBS surfaces, and polygon meshes are alternative technologies. To smoothly join at points where more than three surface pieces meet, T-splines have been combined with geometrically continuous constructions of degree 3 by 3 (bi-cubic) and, more recently, of degree 4 by 4 (bi-quartic). In practice, enormous amount of programming was required to make NURBS work as well as they do, and creating the equivalent T-Spline functionality would require similar effort. T-splines can therefore, in theory, do everything that NURBS can do. T-splines can be converted into NURBS surfaces, by knot insertion, and NURBS can be represented as T-splines without T's or by removing knots. Modeling surfaces with T-splines can reduce the number of control points in comparison to NURBS surfaces and make pieces easier to merge, but increases the book-keeping effort to keep track of the irregular connectivity. The control net at a terminated row resembles the letter "T". A T-spline surface is a type of surface defined by a network of control points where a row of control points is allowed to terminate without traversing the entire surface. T-spline is a mathematical model for defining freeform surfaces in computer graphics.
