[vtkusers] Actor->Render()

[Louis Desjardins]

Hi vtkexperts,

I was wondering if anyone has tried rendering actors using the 
vtkActor::Renderer( Renderer * , Mapper * ) function (I'm doing this as a 
means to have more immediate mode control).

// Ren1 contains no actors
RenWin->AddRenderer( Ren1 );

RenWin->Render();
Actor->Render();

However this just renders a black screen.. On the vtk site however it 
indicates that calling vtkActor::Renderer causes the actor to be rendered, 
so I must be doing something wrong.. but I'm not sure what..

If anyone has any tips that would be greatly appreciated,
thank you again,

LD
