From: Filling N-Sided Holes With Trimmed B-Spline Surfaces Based on Energy-Minimization Method
J. Comput. Inf. Sci. Eng. 2015;15(1): doi: /
Figure Legend:
Filling a six-sided hole: The method discussed in this paper uses one single rectangular B-Spline surface with 12 × 12 = 144 control points to fill the six-sided hole. (The hole is shown as a small picture at the bottom right. To demonstrate the operation of filling an n-sided hole, the entire untrimmed rectangular B-Spline surface is shown.) The tolerance requirement is less than 1.0 × 10−6 m.
