T-Spline Simplification
… on generating approximations of complex T-spline surfaces with similar but less complex T-splines. Two approaches to simplifying T-splines are proposed: a bottom-up approach that iteratively refines an over-simple T-spline to approximate a complex one, and a top-down approach that evaluates …

T-spline Merging
… The recent invention of a surface type called T-splines has made the combining of NURBS surfaces into a single continuous surface possible, but much of the mathematics has yet to be explored. This thesis explores the mathematics and algorithms necessary to merge multiple NURBS, T-spline, or …

Arbitrary Degree T-Splines
<p>T-Splines is a freeform surface type similar to NURBS, that allows partial rows of control points. Up until now, T-Splines have only been formally defined for the degree three case. This paper extends the definition to support all odd, even, and mixed degree T-Spline surfaces, making T-Splines a …

Space--Time Computation of a Ringsail Parachute With Model Thickness
… of control points, thus converting NURBS to a T-spline representation. This study begins with, for a single gore of an Orion spacecraft parachute, a flow comparison between the models with and without fabric thickness. It concludes with, for the full-canopy Orion spacecraft parachute, flow …
