Key Concepts

Bézier Curve

A Bézier curve is a parametric curve frequently used in computer graphics, animation, and related fields for modeling smooth curves. It is defined by a set of control points and uses Bernstein polynomials to blend these points, providing an intuitive way to manipulate the shape of the curve. The curve is generated as a weighted sum of the control points where the weights depend on the parameter value.

Control Points

Control points are specific points that determine the shape and direction of a Bézier curve. They serve as the basis for the curve’s construction; by altering these points, one can easily adjust the curvature. In a Bézier curve, the first and last control points are typically the endpoints of the curve, while the intermediate points influence its bending and tension.

Bernstein Polynomials

Bernstein polynomials form the mathematical foundation of the Bézier curve formulation by serving as basis functions. These polynomials have properties such as non-negativity and a partition of unity, ensuring that the curve’s generated points are a smooth blend of the control points. They provide the necessary weights in the Bézier curve equation, allowing for an elegant parametric definition.

Parametric Representation

Parametric representation involves expressing the coordinates of the curve as functions of a parameter, commonly denoted as t, which typically ranges from 0 to 1. This approach enables a systematic method of computing points along the curve and is essential in both theoretical analysis and practical applications such as rendering and animation.

Plotting

Plotting a Bézier curve involves computing a sufficient number of points along the parameter t from 0 to 1 using the curve’s defining equation and then visualizing these points in a coordinate space. This process is important for verifying the curve’s shape and properties, and it plays a crucial role in computer-aided design and graphics to ensure that the mathematical model matches the visual output.
