Issue with LineMaterial (and LineDashedMaterial)?

I am trying to created a dashed line, as in this example.
Using LineBasicMaterial
produces a solid line as expected:
x = [0, 10, 20, 30]
y = [0, 10, 0, 10]
a = array=np.array(
[x, y, np.zeros_like(x)],
dtype='float32').T
geometry = p3.BufferGeometry(
attributes={
'position':
p3.BufferAttribute(array=a),
})
material = p3.LineBasicMaterial(color='red', linewidth=10)
line = p3.Line(geometry=geometry, material=material)
line
However, when using either LineMaterial
or LineDashedMaterial
, no line is visible:
x = [0, 10, 20, 30]
y = [0, 10, 0, 10]
a = array=np.array(
[x, y, np.zeros_like(x)],
dtype='float32').T
geometry = p3.BufferGeometry(
attributes={
'position':
p3.BufferAttribute(array=a),
})
material = p3.LineMaterial(color=color, linewidth=10)
# material = p3.LineDashedMaterial(color='red', linewidth=10)
line = p3.Line(geometry=geometry, material=material)
line
Am I doing something wrong, or is it a bug? Thanks!

I also tried with LineGeometry
, which shows nothing with LineBasicMaterial
, and shows something strange with LineMaterial
:
x = [0, 10, 20, 30]
y = [0, 10, 0, 10]
a = array=np.array(
[x, y, np.zeros_like(x)],
dtype='float32').T
geometry = p3.LineGeometry(positions=a)
material = p3.LineMaterial(color=color, linewidth=10)
line = p3.Line(geometry=geometry, material=material)
line

LineMaterial
is an "extra" material, but it seems it only supports LineSegments2
(also extra). I see that a Line2
object was also started, but only supports Geometry
for the geometry attribute. Please consult the ThickLines
example as much as possible: it also outlines the shader that is used, and some of the options available.
