Closed b spline
WebB-Spline, Periodic Now in order to create a closed curve like the following, which is another Mathematica example that can be found on the web, it is necessary to set the per parameter in the splrep call, if you use that. After padding the list of control points with degree+1 values at the end, this seems to work well enough, as the images show. WebNov 6, 2024 · Closed b-spline. I want to write a closed b spline function which takes [k (degree is k-1), x coordinate and y coordinates of control points] as inputs. I am unable to …
