Fury Arrow Actor

This example shows how to use the arrow actor.

import numpy as np

from fury import actor, window

First thing, you have to specify centers, directions, and colors of the arrow(s)

centers = np.zeros([3, 3])

np.identity is the same as specifying x, y, and z directions.

dirs = np.identity(3)
colors = np.identity(3)
scales = np.array([2.1, 2.6, 2.5])

The below arrow actor is generated by repeating the arrow primitive.

arrow_actor = actor.arrow(centers, dirs, colors=colors, scales=1.5)

repeating what we did but this time with random centers, directions, and colors.

cen2 = np.random.rand(5, 3)
dir2 = np.random.rand(5, 3)
cols2 = np.random.rand(5, 3)

arrow_actor2 = actor.arrow(cen2, dir2, colors=cols2, scales=1.5)

scene = window.Scene()

Adding our Arrow actors to scene.

scene.add(arrow_actor)
scene.add(arrow_actor2)

interactive = False

if interactive:
    window.show(scene, size=(600, 600))

window.record(scene, out_path='viz_arrow.png', size=(600, 600))
