Examples

Basic

import numpy as np

o = np.array([[0, 0, 0],
              [2, 3, 4]]).astype(np.float32)

v = np.array([[1, 1, 1],
              [-2, -2, -2]]).astype(np.float32)

plt_vectors = k3d.vectors(origins=o,
                          vectors=v,
                          colors=[0x000000, 0xde49a1,
                                  0x000000, 0x40826d])

plot = k3d.plot()

Labels

              [2, -3, 0]]).astype(np.float32)

v = np.array([[1, 1, 1],
              [-4, 2, 3]]).astype(np.float32)

labels = ['(1, 1, 1)', '(2, -3, 0)']

plt_vectors = k3d.vectors(origins=o,
