Error with VTK 9.3.0

[lciorciaro]

VTK version 9.3.0 produces an error in mayavi. The following code

from mayavi import mlab
import numpy as np

x = np.array([1, 1, 1, 2, 2, 2, 3, 3, 3])
y = np.array([11, 12, 13, 11, 12, 13, 11, 12, 13])
vs = np.array([5] * len(x))

fig = mlab.figure(1, fgcolor=(0, 0, 0), bgcolor=(1, 1, 1), size=(1400, 1900))

pts = mlab.points3d(x, y, vs, vs, scale_mode='none', scale_factor=0.2, figure=fig)

mlab.view(azimuth=8, elevation=65, distance=65)
mlab.show()

produces the error

Under VTK version 9.2.6 everything works for me.

I am having the same issue, unfortunately if I go down to VTK 9.2.6, then I get a mismatch between TVTK (VTK=9.3) and VTK (VTK=9.2.6), and other parts of the application I have fail.

I'm also facing this issue and I was able to isolate it to the "mayavi.mlab.points3d" call.

Apologies for the inactivity. Fixed in release 4.8.2.
