Constructing Bezier curves

Bezier curves, or B-splines, are a family of curves that are extremely useful in vector graphics – for instance, they are commonly used in high-quality font packages. This is because they are defined by a small number of points that can then be used to inexpensively calculate a large number of points along the curve. This allows detail to be scaled according to the needs of the user.

In this recipe, we’ll learn how to create a simple class representing a Bezier curve and compute a number of points along it.

Getting ready

In this recipe, we will use the NumPy package imported as np, the Matplotlib pyplot module imported as plt, and the comb routine from the Python Standard Library math module, imported under the binom alias:

from math import comb as binom
import matplotlib.pyplot as plt
import numpy as np
