Hi,
The vertex visibility of a PolyData cannot be changed after the first renderWindow->Render();
Any change to its attributes (e.g. color, size,…) works, but visibility is stuck in the previous state.
For reproduction, you can take this code:
https://gitlab.kitware.com/vtk/vtk/-/blob/master/Rendering/Core/Testing/Cxx/TestVertexVisibility.cxx
and add renderWindow->Render();
on line 45
Is this normal behavior?
Thanks in advance,
Julien
