I add the plan in this way but nothing is displayed.
const planeSource = vtkPlaneSource.newInstance({xResolution: 100, yResolution: 100 });
const planeMapper = vtkMapper.newInstance();
const planeActor = vtkActor.newInstance();
planeMapper.setInputData(planeSource.getOutputData());
planeActor.setMapper(planeMapper);
this.view3D.renderer.addActor(planeActor);
