This is a simple implementation of creating
Bezier curves from a list a control points
in Python.
from matplotlib import pyplot as plt
from Bezier import bezier_curve
nPoints = 4
points = np.random.rand(nPoints,2)*200
xpoints = [p[0] for p in points]
ypoints = [p[1] for p in points]
xvals, yvals = bezier_curve(points, nTimes=1000)
plt.plot(xvals, yvals)
plt.plot(xpoints, ypoints, "ro")
for nr in range(len(points)):
plt.text(points[nr][0], points[nr][1], nr)
plt.show()
