Bezierkäyrän

Bezierkäyrän, also known as a Bezier curve, is a parametric curve used in computer graphics and related fields. It is named after its inventor, Pierre Bézier, who used it in the 1960s for designing automobile bodies. The curve is defined by a set of control points, and its shape is determined by the positions of these points. The curve starts at the first control point and ends at the last control point, but it does not generally pass through any of the other control points. Instead, the curve is a smooth, continuous path that is tangent to the line segments connecting the control points at the start and end points. The curve is widely used in computer-aided design (CAD), animation, and other applications where smooth, precise curves are required. It is also used in font design, where it allows for the creation of complex, smooth letterforms. The Bezier curve is a fundamental tool in computer graphics, and its versatility and ease of use have made it a staple of the field.
