Project description
Helper for Bézier Curves, Triangles, and Higher Order Objects
Install
$ pip install --upgrade bezierGetting Started
For example, to create a curve:
>>> nodes1 = np.array([
... [0.0, 0.0],
... [0.5, 1.0],
... [1.0, 0.0],
... ])
>>> curve1 = bezier.Curve(nodes1, degree=2)The intersection (points) between two curves can also be determined:
>>> nodes2 = np.array([
... [0.0 , 0.0],
... [0.25, 2.0],
... [0.5 , -2.0],
... [0.75, 2.0],
... [1.0 , 0.0],
... ])
>>> curve2 = bezier.Curve.from_nodes(nodes2)
>>> intersections = curve1.intersect(curve2)
>>> intersections
array([[ 0.311..., 0.428...],
[ 0.688..., 0.428...],
[ 0. , 0. ],
[ 1. , 0. ]])and then we can plot these curves (along with their intersections):
>>> import matplotlib.pyplot as plt
>>> import seaborn
>>>
>>> ax = curve1.plot(num_pts=256)
>>> curve2.plot(num_pts=256, ax=ax)
>>> ax.plot(intersections[:, 0], intersections[:, 1],
... marker='o', linestyle='None', color='black')
>>> ax.axis('scaled')
>>> ax.set_xlim(-0.125, 1.125)
>>> ax.set_ylim(-0.0625, 0.625)
>>> plt.show()
