@joojaa Hi, May I ask you a question about interpolate a set of points with closed B-spline curve . Please see here

Aug 27, 2015 at 11:05 | comment | added | joojaa | @EcirHana Done do you need the multiplicity explanation here | |

Aug 26, 2015 at 21:31 | comment | added | Ecir Hana | Typo perhaps? "Instead the underlying surface has a customizable parameter range. The parameter is stored in something called a knot, and each knot can have a arbitrary value that is bigger than the next." -> "Instead the underlying curve has a customizable parameter range. The parameter is stored in something called a knot, and each knot can have a arbitrary value that is bigger than the previous." Btw., could you please clarify what you mean by "UV range"? "UV" implies 2D..? | |

Aug 26, 2015 at 14:16 | comment | added | Alan Wolfe | I think your statement about length is wrong (only works with linear functions?), and not sure how length calculations is supposed to fit in your explanation (good info you gave, just sayin'!) | |

Aug 26, 2015 at 14:04 | comment | added | Alan Wolfe | regarding (*), Bezier curves have the same problem. The issue there is that the curves (in both cases) are defined as x = f(t), y = f(t). However, you can also define a univariate / explicit / 1 dimensional curve (again, in both cases) as y = f(x), using x in place of t. In the case of rational curves, instead of being able to represent conic sections, you can represent sine and cosine (and more of course). NURBS / b-splines aren't special in that regard. | |
