When I used Pyvista to display the mesh model in vtk file, I found that Pyvista based on vtk kernel cannot draw and display all edges of the mesh in vtk files.
Please help solve this problem. Many thanks.
Here is my code:
import pyvista as pv
my\_mesh = pv.read(“D:/mesh\_file/test.vtk”)
plotter = pv.Plotter()
\_ = plotter.add\_mesh(my\_mesh, color = ‘#BBFFFF’, style = ‘surface’, show\_edges = True,
edge\_color = ‘#EE8262’, line\_width = 0.5, opacity = 1.0)
plotter.show()
The following link can get the vtk file.

I responded on the original PyVista issue.

Now, I directly use the python API of vtk to display the model, but I still can’t solve this problem. How should I solve this problem?
Part of my code is as follows:
reader = vtk.vtkUnstructuredGridReader()
reader.SetFileName(mesh\_file\_name)
reader.Update()
output = reader.GetOutput()
self.mapper = vtk.vtkDataSetMapper()
self.mapper.SetInputData(output)
self.mapper.ScalarVisibilityOff()
self.actor = vtk.vtkActor()
self.actor.SetMapper(self.mapper)
self.actor.GetProperty().EdgeVisibilityOn()
self.actor.GetProperty().SetLineWidth(2.0)
surface\_color = [51, 161, 201]
surface\_color = [x/255.0 for x in surface\_color]
self.actor.GetProperty().SetColor(surface\_color)
Many Thanks!
