I am trying to use a vtk window. I have expected behavior when using this
@param.depends('refresh_views')
def view_vtk(self):
return pn.pane.VTK('https://raw.githubusercontent.com/Kitware/vtk-js/master/Data/StanfordDragon.vtkjs')
Then I use my own vtk plot:
@param.depends('refresh_views')
def view_vtk(self):
return pn.pane.VTK(self.get_3dplot().plotter.ren_win)
But this plot isn’t updated, even though view_vtk() is called for sure. When I refresh the page with F5, I do get the updated plot, but also the error message below, which I find quite puzzling (and doesn’t really seems to break anything).
The vtk plot is fine as it can be viewed natively with pyvista using the show() method.
Any clues what I am doing wrong?
