What is a Bezeir curve?
The Bezier curve is the standard curve type used in most
graphics software. It is unusual in that it has no more than four
points (as opposed to other kinds of curves, which can have many
points): two endpoints and up to two control points. The position
of the control points determines the shape of the curve. The Bezier
curve can also curve back upon itself, which many other computer
graphics curves can't. The Bezier curve was patented by Pierre
Bezier, an engineer at Renault. The first project ever done using
Bezier curves was the Renault Le Car.
