样条、B 样条和 NURBS C++ 库

Spline, B-Spline and NURBS C++ library

提问by CVertex

Does anyone know of a library or set of classes for splines - specifically b-splines and NURBS (optional).

有谁知道样条曲线的库或一组类 - 特别是 b 样条曲线和 NURBS（可选）。

A fast, efficient b-spline library would be so useful for me at the moment.

一个快速、高效的 b-spline 库目前对我来说非常有用。

1.) For B Splines - You should check Numerical Recipes in C (there is book for that and it is also available online for reference)

1.) 对于 B 样条 - 您应该检查 C 中的数值食谱（有书，也可以在线获取以供参考）

2.) Also check: sourceforge.net/projects/einspline/& this

2.) 还要检查：sourceforge.net/projects/einspline/& this

I know I'm answering months after this question was asked, but for others who might be searching for a similar answer, I'll point out openNURBS.

我知道我在问这个问题几个月后才回答，但对于可能正在寻找类似答案的其他人，我会指出openNURBS。

OpenNURBS also happens to be the library used in the modeling package Rhinoceros. It's a very complete library and it's worth consideration.

OpenNURBS 也恰好是建模包Rhinoceros 中使用的库。这是一个非常完整的库，值得考虑。

This library may also be promising: http://libnurbs.sourceforge.net

这个库也可能很有前途：http: //libnurbs.sourceforge.net

Also ITK has a class for bspline itkBSplineScatteredDataPointSetToImageFilter see example at http://www.itk.org/Wiki/ITK/Examples/WishList/PointSet/BSplineScatteredDataPointSetToImageFilter( documentation at http://www.itk.org/Doxygen/html/classitk_1_1BSplineScatteredDataPointSetToImageFilter.htmlhttp://www.itk.org/Doxygen/html/classitk_1_1BSplineScatteredDataPointSetToImageFilter.html)

此外，ITK 有一个 bspline itkBSplineScatteredDataPointSetToImageFilter 类，请参见http://www.itk.org/Wiki/ITK/Examples/WishList/PointSet/BSplineScatteredDataPointSetToImageFilter（文档位于http://www.itk.org/Doxygen/html/classitk_1_1BSplineToImageFilterDataPointSet .html http://www.itk.org/Doxygen/html/classitk_1_1BSplineScatteredDataPointSetToImageFilter.html)

Eigen Splineis based on the famous (fast) C++ template library for linear algebra.

Eigen Spline基于著名的（快速）C++ 线性代数模板库。

An excellent library that is also supplemented by an online book is from MIT. Here is the (hyper)book http://web.mit.edu/hyperbook/Patrikalakis-Maekawa-Cho/mathe.html

一个优秀的图书馆也有一本在线书籍作为补充来自麻省理工学院。这是（超级）书 http://web.mit.edu/hyperbook/Patrikalakis-Maekawa-Cho/mathe.html

and in the bottom of the link you will find the related software, here: http://web.mit.edu/hyperbook/Patrikalakis-Maekawa-Cho/software.html

GSL has a nice very basic b-spline implementation, but it does not include NURBS curves neither algorithms for inserting/removing knots, or several more advanced things. You can also find many useful algorithms that you can compile in your own language in the book, "The NURBS book", Piegl & Tiller, this one: http://www.amazon.com/NURBS-Book-Monographs-Visual-Communication/dp/3540615458

GSL 有一个很好的非常基本的 b 样条实现，但它不包括 NURBS 曲线、插入/删除结的算法或一些更高级的东西。您还可以在“The NURBS book”、Piegl & Tiller 一书中找到许多可以用您自己的语言编译的有用算法，这本：http://www.amazon.com/NURBS-Book-Monographs-Visual- 通讯/dp/3540615458

Numerical Recipes do not include support for b-splines.

数值配方不包括对 b 样条的支持。

SISLseems to be a good NURBS library (under the AGPL licence). It is part of GoToolswhich can be cloned here.

SISL似乎是一个很好的 NURBS 库（在 AGPL 许可下）。它是GoTools 的一部分，可以在这里克隆。
