T-SPLINE

T-spline is a new approach to define freeform surfaces with relatively less control points than NURBS and is able to represent a model using a single surface without joining errors. Whereas, the complexity of T-spline data models leads numerous difficulties in its programming, which hinders the research and development of T-spline technologies. Here, the T-SPLINE kernel gives a set of redesigned data models which have much more understanding conveniences to both human and computer.
