What Is Bézier Curve?

✍: FYIcenter.com

A

Bézier Curve, named after Pierre Bézier, is related to Bernstein polynomial and widely used in computer graphics.

The Bézier Curve B_{p₀p₁...p_n}(t) for a given set of n+1 points p₀, p₁, ..., p_n with t=(0,1) can be defined in the following recursive form:

B_p₀(t) = p₀, t=(0, 1)
B_{p₀p₁...p_n}(t) = (1-t)B_{p₀...p_n-1} + tB_{p₁...p_n}, t=(0, 1)

Graphically, a 2-point Bézier Curve B_p₀p₁(t) can be presented as:

Graphically, a 3-point Bézier Curve B_p₀p₁p₂(t) can be presented as:

Graphically, a 4-point Bézier Curve B_{p₀p₁p₂p₃}(t) can be presented as:
