I have posted it in vtk forum: https://discourse.vtk.org/t/vtkclippolydata-incorrectly-work/13046

Thanks for kindly reply. And I find `pygmsh` may be a solution. My test code is: ``` import pygmsh from vedo import * with pygmsh.geo.Geometry() as geom: box = geom.add_ball(x0=[0,...

Finally, I can repeat the bug: ``` vtkSmartPointer lineSource = vtkSmartPointer::New(); lineSource->SetPoint1(0, 0, 0); lineSource->SetPoint2(10, 0, 0); vtkSmartPointer tubeFilter = vtkSmartPointer::New(); tubeFilter->SetInputConnection(lineSource->GetOutputPort()); tubeFilter->SetRadius(4); ///////////////////////////////////////////////////////////////////////////// tubeFilter->SetNumberOfSides(50); // key code ///////////////////////////////////////////////////////////////////////////// tubeFilter->SetCapping(1);...

I find the following code works: ``` from vedo import * plt = Plotter() p = Point([0, 0, 1], r=10) plt.show(p) plt = Plotter() p = Point([0, 1, 0], r=10,...

It is `2023.4.3`

I have a same error

> hi, sorry for the late reply... I also tried but could not find a way to make it work.. unfortunately the boolean operations in vtk are a weak point...
