Hi,

I apologize if this is just a stupid bug on my part – I am new to FURY -  but this is my issue:

I am trying to define multiple lines in a scene as multiple independent actors, but when I do so the renderer adds an extra line that connects one of the ends to the origin. This does not happen if I define a single actor with multiple lines.

I am running on multiple python versions (3.8,3.9) and on multiple Mac systems (Mac Pro, iMac, MacBook Pro) with the same result.

To reproduce the issue:

Single actor:

scene = window.Scene()

scene.SetBackground((255,255,255))

lines = []

for n in range(5):

    lines.append(np.random.rand(2, 3))

colors = [np.random.rand(2, 3)]*5

c = actor.line(lines, colors, opacity= 1.0, lod=False,

        fake_tube=True, linewidth=3)

scene.add(c)

window.show(scene)

Multiple actors:

scene = window.Scene()

scene.SetBackground((255,255,255))

lines = []

for n in range(5):

    lines.append(np.random.rand(2, 3))

colors = [np.random.rand(2, 3)]*5

line_actor = []

for n in range(5):

    line_actor.append(actor.line(lines[n], colors[n], opacity= 1.0, lod=False,

        fake_tube=True, linewidth=3))

    scene.add(line_actor[n])

window.show(scene)

Thank you very much for any suggestion you can give me!

Best
