Summary0011164: vtkAssembly does not implement the vtkProp::RenderOverlay(vtkViewport * ren) method
DescriptionThe vtkAssembly of 5.6.0 does not have the recursive method:
    int vtkPropAssembly::RenderOverlay(vtkViewport * ren);

Hybrid 2D/3D actors like vtkAxesActor do implement this method to get their 2D data rendered. The vtkAssembly does need this method, too. Not only because of the existence of these classes but rather because of their base class vtkProp3D which only defines the abilities to get positioned and oriented in 3D space and NOT that they are restricted to only render 3D graphics.

E.g. if you don't add this method to vtkAssembly, the vtkAxesActor cannot display its caption labels when it has been added to the a vtkAssembly.
Additional InformationHere is the code of the method I've added to vtkAssembly.cxx:

// Render this assembly and all its parts. The rendering process is recursive.
int vtkAssembly::RenderOverlay(vtkViewport *ren) {
  vtkProp3D *prop3D;
  vtkAssemblyPath *path;
  double fraction;
  int renderedSomething=0;

  // Make sure the paths are up-to-date
  this->UpdatePaths();
  
  // for allocating render time between components
  // simple equal allocation
  fraction = this->AllocatedRenderTime
    / static_cast<double>(this->Paths->GetNumberOfItems());
  
  vtkCollectionSimpleIterator sit;
  for ( this->Paths->InitTraversal(sit); (path = this->Paths->GetNextPath(sit)); )
    {
    prop3D = static_cast<vtkProp3D *>(path->GetLastNode()->GetViewProp());
    if ( prop3D->GetVisibility() )
      {
      prop3D->SetAllocatedRenderTime(fraction, ren);
      prop3D->PokeMatrix(path->GetLastNode()->GetMatrix());
      renderedSomething += prop3D->RenderOverlay(ren);
      prop3D->PokeMatrix(NULL);
      }
    }

  renderedSomething = (renderedSomething > 0)?(1):(0);

  return renderedSomething;
}

 I've patched the files by my own and uploaded them. They are based on VTK 5.6.0.
