This paper provides the description of a novel, multi-purpose spline library. In accordance with the increasingly diverse modes of usage of splines, it is multi-purpose in the sense that it supports geometry representation, finite element analysis, and optimization. The library features reading and writing for various file formats and a wide range of spline manipulation algorithms. Further, a new efficient and objective-oriented algorithm for B-spline basis function evaluation is included. All features are available by a spline-type independent interface. The library is written in modern C++ with CMake as build system. This enables it for usage in typical scientific applications. It is provided as open-source library.

本文提供了一种新颖的多功能样条库的描述。根据样条线使用方式的日益多样化，从某种意义上说，它支持几何图形表示，有限元分析和优化，因此具有多种用途。该库具有读写各种文件格式和多种样条处理算法的功能。此外，还包括一种用于B样条基函数评估的高效且面向目标的新算法。所有功能都可通过样条类型的独立界面使用。该库是使用CMake作为构建系统的现代C ++编写的。这使其可以在典型的科学应用中使用。它作为开源库提供。
