Usually the curve is intended to approximate a real-world shape that otherwise has no mathematical representation or whose representation is unknown or too complicated. The Bézier curve is named after French engineer Pierre Bézier (1910–1999), who used it in the 1960s for designing curves for the bodywork of Renault cars. [3]
For higher degrees of curve, P0 P1 and P2 aren't defined by the grey lines anymore- they're defined by a chain of parent functions that go all the way up to the grey lines through the same algorithm. So these intermediate line segments show how Bezier curves are algorithmically constructed, although mathematically the curve can still be ...
It is similar to a polygon in that it connects a set of vertices by lines, but whereas in polygons the vertices are connected by straight lines, in a béziergon the vertices are connected by Bézier curves. [2] [3] [4] Some authors even call a composite Bézier curve a "Bézier spline"; [5] the latter term is however used by other authors as a ...
Examples include the plane, the lateral surface of a cylinder or cone, a conical surface with elliptical directrix, the right conoid, the helicoid, and the tangent developable of a smooth curve in space. A ruled surface can be described as the set of points swept by a moving straight line.

Quadratic Bèzier curves in string art: Image title: Illustration of quadratic Bèzier curves in string art by CMG Lee. In each case, end points marked with black circles and the control point marked with an X define the quadratic Bèzier curve shown as a dotted line. Width: 100%: Height: 100%
The list is full of examples of this art style and movement that were created by artists from all around the world. So, check them out; maybe it will convince you to become a surrealism enthusiast.
The smooth portions of a curve are then approximated with a Bézier curve fitting procedure. Successive division may be used. Such a fitting procedure tries to fit the curve with a single cubic curve; if the fit is acceptable, then the procedure stops. Otherwise, it selects some advantageous point along the curve and breaks the curve into two ...
