Bezigon

In computer graphics, a bezigon is similar to a polygon, but its sides are Bézier curves instead of straight lines.

Bézier curves are named after French engineer and mathematician Pierre Bézier, and use computationally simple cubic polynomial parametric equations to create complex curves.

Bezigons can be made big or small or rotated with no "jaggies". Adobe PostScript fonts are made up of bezigons. Bezigons can be used to create scalable shapes directly.

Bezigons can trace bitmap images to convert them to vector graphics.
