A bezier curve will be drawn for you.
Notice how the Bezier curve is redrawn according to the new control points.
Bezier curves are created by taking a time-varying linear combination of the control points.

 Approximating Cubic Bezier Curves in Flash MX
Bezier curve changed the way graphics were thought of and introduced the concept of vector graphics as opposed to raster images.
Bezier curves are parametric curves, it means the formula above is applied independently to the x and y coordinate of the points for a 2D curve.
It is possible to ensure continuity of two bezier curves by making sure that the tangent to the last control point of the first curve is the same as the tangent to the first control point of the second curve.

 labs.zeh.com.br » Blog Archive » The search for the perfect bezier tweening syntax
The most recent of such challenges was implementing beziér curves on tweenings.
From this example, it’s also possible to notice one quasi-caveat of quadratic bezier curves: depending on how you setup your control points, or how your curves are laid out, it will change the speed of travel an object could have when sliding through the path.
You can notice this happens by looking at the circles distributed among the curves, when you create a very acute curve: if the circles are too close to each other on a specific point of the path, that means a point of deceleration.

The corresponding properties of the Bézier curve apply to the Bézier surface.
Along the edges of the grid patch the Bézier surface matches that of a Bézier curve through the control points along that edge.
Normally, if the number of control points is constant, the blending function would be calculated once for each desired value of mu.

 Bezier Curves and DHTML :: pupius.co.uk
In a quadratic (2nd order) curve there would only be 3 functions and in a quartic (4th order) there would be 5.
The first being the start point, the next 2 define the shape of the curve and the final point is the end point.
Example 2: Uses one curve to define the point on another curve, gives a bouncing ball effect (same method as used in the 13th API's timeSlide() function)

 Nonlinear Design. Bezier curves - webreference.com
A Bezier curve may be smooth and streamlined, but it may have very sharp turns and even fractures; it may have one or two bends, and even form loops (Fig.
Now, Bezier curves are used almost exclusively for creating curvilinear shapes in all fields of design, from purely technical plans and blueprints to the most creative artistic genres.
In the next sections, we'll try to discover the laws governing the world of Bezier curves, in the hope that these laws can, at least partially, explain their beauty and expression and provide directions for successfully using them in design.
