贝塞尔曲线(Bezier curve),由法国数学家Pierre Bezier于 1962 年提出的一种矢量曲线。又称贝兹曲线或贝济埃曲线,是应用于二维图形应用程序的数学曲线。一般的矢量图形软件通过它来精确画出曲线,贝兹曲线由线段与节点组成,节点是可拖动的支点,线段像可伸缩的皮筋,我们在绘图工具上看到的钢笔工具就是来做这种矢量曲线的。
我们可以通过将P2和Q0连接起来,形成一个新的Bezier曲线段,从而创建一个复合Bezier曲线。 importmatplotlib.pyplotaspltfromscipy.interpolateimportCubicSplineimportnumpyasnpdefplot_bezier_curve(control_points):t=np.linspace(0,1,100)x=[]y=[]foriinrange(len(control_points)-1):forjinrange(len(control_poin...
A bezier handle is the little “wing” that comes off any anchor point created with the pen tool that creates the curve in a line. If you drag it out further, the curve becomes greater. It is created by clicking and dragging with the pen tool to create a new point. If you click ...

Even though GDI has a built-in Bezier curve calculation function, it is never good for learning to use built-in libraries. You won't always have GDI to do things for you! At some place, some time, you may have to implement it, and I think by now, you should have a rough idea of...
The first one allows me to drag independent handles on a curve point. The middle one drags a curt handle off of a sharp point and the last one is the symmetrical tool that drags both handles out or in at an equal distance. If that tool is chosen, a point with two unequal length ...
