DXF文件中非均匀有理B样条曲线接口的研究

Interface research on non-uniform rational B-Spline of DXF file

由于AutoCAD应用十分广泛,了解它的图形交换文件对于很多行业是很重要的,简要分析了DXF数据文件格式,深入研究了DXF文件中非均匀有理B样条曲线格式,并且给出了读取非均匀有理B样条的算法。

The applications of AutoCAD are very wide It is very important to understand DXF file in AutoCAD for all trades. This paper briefly analyzes the format of DXF, discusses in detail non-uniform rational B-spline curve format, and gives the algorithm of reading non-uniform rational B-spline.
