Cubic B-spline curve in Java

I need to use cubic B - spline, but I can't find its code anywhere The only curves available in the Java API are quadcurve2d, path2d, and cubiccurve2d I think they're all Bezier, but I'm not sure

If you know where to find the cubic B-spline code, you'd better extend the Java shape class and support the inclusion of OnMouseOver (point P). Please help

Solution

Apache has a class that represents splines:

http://jmeter.apache.org/api/org/apache/jmeter/visualizers/Spline3.html

However, it does not extend shape or support what you want This class works by inserting curves between nodes using cubic curves For contains (point P), you can use the getplots () method to compare its results with the X and Y values of P
