Abstract
This paper introduces S-spline curves and surfaces. Local refinement of S-spline surfaces is much simpler to understand and to implement than T-spline refinement. Furthermore, no unwanted control points arise in S-spline refinement, unlike T-spline refinement. The refinement algorithm assures null linear independence null null of null blending functions . Thus, for isogeometric analysis, S-spline surfaces provide optimal degrees of freedom...
