question: public static GeneralPath cardinalSpline ( float pts [ ] , int start , int npoints , float slack , boolean closed ) { GeneralPath path = new GeneralPath ( ) ; path . moveTo ( pts [ start ] , pts [ start + 1 ] ) ; return cardinalSpline ( path , pts , start , npoints , slack , closed , 0f , 0f ) ; }
target:  Compute a cardinal spline, a series of cubic Bezier splines smoothly connecting a set of points. Cardinal splines maintain C(1) continuity, ensuring the connected spline segments form a differentiable curve, ensuring at least a minimum level of smoothness.
