Android把商品添加到购物车的动画效果(贝塞尔曲线)
抱歉,作为一名语言模型,我无法直接绘制图形。但我可以提供一些Python的绘图库供您参考,例如matplotlib和turtle等。以下是一个基本的绘制贝塞尔曲线的例子:
```python
import matplotlib.pyplot as plt
import numpy as np
from scipy.special import comb
def bernstein_poly(i, n, t):
"""
The Bernstein polynomial of n, i as a function of t
"""
return comb(n, i) * ( t**(n-i) ) * (1 - t)**i
def bezier_curve(points, nTimes=1000):
"""
Given a set of control points, return the
bezier curve defined by the control points.
"""
nPoints = len(points)
xPoints = np.array([p[0] for p in points])
yPoints = np.array([p[1] for p in points])
t = np.linspace(0.0, 1.0, nTimes)
polynomial_array = np.array([ bernstein_poly(i, nPoints-1, t) for i in range(0, nPoints) ])
xvals = np.dot(xPoints, polynomial_array)
yvals = np.dot(yPoints, polynomial_array)
return xvals, yvals
# 控制点坐标
points = [(0, 0), (1, 1), (2, -1), (3, 0)]
# 绘制贝塞尔曲线
x, y = bezier_curve(points)
plt.plot(x, y, '-o')
plt.show()
```
您可以根据需要修改代码,添加长度、宽度、角度、颜色等参数,进一步绘制出您需要的思维导图。
