Requirements

---

1. Lang: None
2. Python 3 installed
3. Matplotlib installed

Usage

---

Illustrate all animation of a bezier curve

from matplotlib import pyplot as plt
from bezier import illustrate

fig = plt.figure()

points = [[0, 0], [3, 3], [6, 0]]
b = illustrate(fig, points, interval=50, n=100)

plt.show()

Sketch a bezier curve

from matplotlib import pyplot as plt
from bezier import sketch

fig = plt.figure()
plt.xlim(-1, 11)
plt.ylim(-2, 8)
b = sketch(fig, [[0, 0], [5, 5], [10, 0]], color='b')
plt.show()

Moving line, moving dot motion

from matplotlib import pyplot as plt
from bezier import Bezier
import numpy as np

fig = plt.figure()
plt.xlim(0, 10)
plt.ylim(0, 10)
left_x = np.linspace(2, 8, 100)
left_y = [8 for x in range(100)]
right_x = np.linspace(2, 8, 100)
right_y = [2 for x in range(100)]
b = Bezier(fig)
a1 = b.vector_animate(left_x, left_y, right_x, right_y, color='k', no_line=True)
a2 = b.line_animate(left_x, left_y, right_x, right_y, color='b')
plt.show()

Feature

---

1. Animate points transformation

Limitations

---

1. Don't pass in too much points, a number between 2 to 10 will be fine, any larger number may cause your machine overstressed
