首先感谢作者的开源代码!!!!
在看的时候也有一些问题想和大家一起交流探讨
首先是BaseFunction中k从0开始取还是从1开始取会有影响嘛?(Heath教材上是从0开始取的)
然后这个generate knot function 的motivation是啥? 自己写的意识到了节点集需要延拓,但是不知道为何是像knot这样延拓的。
最后就是为什么要用uniform_spaced或者centripetal等?可不可以直接用原来数据集的点呢?比如给的11个点就是np.linspace(-5,5,11)就直接给这11个延拓,生成knot。
才疏学浅,再次感谢作者!!!
您好我有许多杂点,但是貌似拟合之后不是很平滑,请问怎么解决,谢谢
您好!请问这个能对插值得到的B曲面求偏导吗?具体如何实现呢?
