Py5Vector.angle_between()#

Measure the angle between two vectors.

Examples#

import numpy as np

v1 = py5.Py5Vector(0, 40)
v2 = py5.Py5Vector(10, 10)
angle = v1.angle_between(v2)
print(f'angle = {round(py5.degrees(angle))}°')
# angle = 45°
angle = np.arccos(v1.norm.dot(v2.norm))
print(f'angle = {round(py5.degrees(angle))}°')
# angle = 45°

def setup():
    py5.translate(20, 20)
    v1 = py5.Py5Vector(60, 0)
    v2 = py5.Py5Vector(45, 45)
    py5.line(0, 0, v1.x, v1.y)
    py5.line(0, 0, v2.x, v2.y)
    angle_radians = v1.angle_between(v2)
