color of tube cap about vedo HOT 4 CLOSED

Thank you, it works perfectly now :)

from vedo.

Hi, consider the following example instead:

from vedo import *

x = np.linspace(0, 2*np.pi, num=20)
y = np.sin(x)
z = np.cos(x)
point_array = np.c_[x, y, z]
scalars = np.sqrt(np.linspace(12, 34, num=20))

line = Line(point_array)
line.pointdata["my_scalars"] = scalars

tube = Tube(line, r=0.5)
tube.cmap("rainbow", "my_scalars")
tube.add_scalarbar3d(":sqrt(myscalars)")

show(tube, axes=1)

in this way - by creating a Line - you will not need to make interpolations.

Weirdly, when I run this code I get these error messages and in the following a grey tube:

[vedo.visual] ERROR: in cmap(), cannot find points array my_scalars ...skip coloring.
[vedo.visual] ERROR: in cmap(), cannot find any points active array ...skip coloring.
[vedo.visual] ERROR: in cmap(), nr. of input cells scalars 0 != 1 ...skip coloring.

Try:

pip install vedo -U
