Bezier Curve

A Bezier curve is a parametric curve defined by a set of control points that determine its shape. The curve starts at the first control point, ends at the last control point, and the other control points affect its curvature. Bezier curves are commonly used in 2D and 3D graphics for drawing curves and surfaces.

Uses the Bernstein Polynomials.

Bezier Curves in Animations

Pretty common to use bezier curves to make animations look more natural as opposed to looking robotic.
