14-point 3D Bezier curve:
Usage
Save the main file Bezier.py into your local directory to import into your python code. Import Bezier and numpy and use. Bezier only has 1 class for now, so you can use this snippet:
from Bezier import Bezier
import numpy as npCreate a Bezier curve with parameter t and a numpy array of inital points points1 of any dimension. Here's a 2D example:
t_points = np.arange(0, 1, 0.01) #................................. Creates an iterable list from 0 to 1.
points1 = np.array([[0, 0], [0, 8], [5, 10], [9, 7], [4, 3]]) #.... Creates an array of coordinates.
curve1 = Bezier.Curve(t_points, points1) #......................... Returns an array of coordinates.You can plot your creations with matplotlib.
import matplotlib.pyplot as plt
plt.figure()
plt.plot(
curve1[:, 0], # x-coordinates.
curve1[:, 1] # y-coordinates.
)
plt.plot(
points1[:, 0], # x-coordinates.
points1[:, 1], # y-coordinates.
'ro:' # Styling (red, circles, dotted).
)
plt.grid()
plt.show()The result:
