http://ask.sagemath.org/question/8294/one-dimensional-nurbs/?answer=13250#post-id-13250I don't know that this is 'natively' available, though we do have some splines - from [GSL](http://hg.sagemath.org/sage-main/file/c239be1054e0/sage/gsl/interpolation.pyx#l1) and a nice [complex spline class](http://hg.sagemath.org/sage-main/file/c239be1054e0/sage/calculus/interpolators.pyx#l1). It doesn't sound like either of these are what you are looking for.
There apparently *does* exist some Python NURBS stuff, though, which would be easy to use within Sage.
* [See this page](http://www.scipy.org/Porting_to_NumPy) and search for NURBS for [something the SciPy people want to integrate](http://runten.tripod.com/NURBS/).
* [This thread](http://mail.scipy.org/pipermail/numpy-discussion/2008-October/038006.html) on the Numpy list also seems relevant, another place where that library was integrated.Sat, 04 Feb 2012 13:33:13 -0600http://ask.sagemath.org/question/8294/one-dimensional-nurbs/?answer=13250#post-id-13250
