Fury Markers

This example shows how to use the marker actor.

import numpy as np
from fury import actor, window
n = 10000

There are nine types 2d markers: circle, square, diamond, triangle, pentagon, hexagon, heptagon, cross and plus.

marker_symbols = ['o', 's', 'd', '^', 'p', 'h', 's6', 'x', '+']
markers = [
    np.random.choice(marker_symbols)
    for i in range(n)]

centers = np.random.normal(size=(n, 3), scale=10)

colors = np.random.uniform(size=(n, 3))

You can control the edge color and edge width for each marker

nodes_actor = actor.markers(
    centers,
    marker=markers,
    edge_width=.1,
    edge_color=[255, 255, 0],
    colors=colors,
    scales=.5,
)

In addition, an 3D sphere it’s also a valid type of marker

nodes_3d_actor = actor.markers(
    centers+np.ones_like(centers)*25,
    marker='3d',
    colors=colors,
    scales=.5,
)

scene = window.Scene()

scene.add(nodes_actor)
scene.add(nodes_3d_actor)

interactive = False

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

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