Drawing of the besell Curve

For example, if there are N points on the screen, we need to connect them with a line. If it is a straight line,

You can simply use moveTo and lineTo. But if it is a curve, for example, when we are drawing a chart,

What should I do if I need to connect N points using the besell curve?

If you think that graphics. curveTo can be used, it will be wrong, because it is difficult to calculate control points,

You cannot connect to a smooth curve.

Fortunately, there is also a third-party class library named cubicbeier, to see the effect of its completion:

 

 

Usage

 

Code

Import flash. display. MovieClip;
Import flash. geom. Point;
This. graphics. lineStyle (x, 1 );
Var points: Array = [];
For (var I: uint = 1; I <8; I ++)
{
Var m: MovieClip = this ["m" + I];
Points. push (new Point (m. x, m. y ));
}
Cubicbezr. curveThroughPoints (this. graphics, points );
