[vtkusers] Clipping objects

[Yunier López Martinez]

Hello , I'm trying to make a clipping to all objects that are in the scene with the same clip function ... 

This is the code I have so far : 

vtkPointSource *points = vtkPointSource::New(); 
points->SetNumberOfPoints(500); 
vtkPolyDataMapper *pmapper = vtkPolyDataMapper::New(); 
pmapper->SetInputConnection(points->GetOutputPort()); 

//vtkActor *pactor = vtkActor::New(); 
//pactor->SetMapper(pmapper); 
//pactor->GetProperty()->SetColor(1,0,0); 

vtkCubeSource *cube = vtkCubeSource::New(); 
vtkPolyDataMapper *cmapper = vtkPolyDataMapper::New(); 
cmapper->SetInputConnection(cube->GetOutputPort()); 

//vtkActor *cactor = vtkActor::New(); 
//cactor->SetMapper(cmapper); 
//cactor->GetProperty()->SetColor(1,1,0); 

vtkPolyDataAlgorithm *all = vtkPolyDataAlgorithm::New(); 
all->AddInputConnection(points->GetOutputPort()); 
all->AddInputConnection(points1->GetOutputPort()); 

vtkPlane* plane = vtkPlane::New(); 
vtkClipPolyData *clip = vtkClipPolyData::New(); 
clip->SetClipFunction(plane); 
clip->InsideOutOn(); 
clip->SetInputConnection(all->GetOutputPort()); 
vtkPolyDataMapper *mapper = vtkPolyDataMapper::New(); 
mapper->SetInputConnection(clip->GetOutputPort()); 
vtkActor *actor = vtkActor::New(); 
actor->SetMapper(mapper); 


//renderer->AddActor(pactor); This does work , but it shows the object without clipping ( logically ) 
//renderer->AddActor(cactor); || 
renderer->AddActor(actor); ----- nothing happens with this 

I want to clarify that I can do the clipping to a single object successfully , even I can do multiple clipping to the same object
