[vtkusers] Interception or Subtract of two polyDatas

[Jose Barreto]

Good afternoon guys,

I'm trying to pick up the interception between two polydatas, a cube and a
sphere.

I tried using vtkBooleanOperationPolyDataFilter and
vtkIntersectionPolyDataFilter
but the output of the two is empty.

the code for vtkIntersectionPolyDataFilter:

                auto cubeSource = vtkSmartPointer<vtkCubeSource>::New();
		cubeSource->SetXLength(size[0]);
		cubeSource->SetYLength(size[1]);
		cubeSource->SetZLength(size[2]);
		cubeSource->Update();

		auto sphereSource = vtkSmartPointer<vtkSphereSource>::New();
		sphereSource->SetRadius(20);
		sphereSource->Update();


		auto  intersectionPolyDataFilter =
vtkSmartPointer<vtkIntersectionPolyDataFilter>::New();
		intersectionPolyDataFilter->SetInputConnection(0,
cubeSource->GetOutputPort());
		intersectionPolyDataFilter->SetInputConnection(1,
sphereSource->GetOutputPort());
		intersectionPolyDataFilter->Update();


But when I using two sphere the output is working.
vtkBooleanOperationPolyDataFilter and vtkIntersectionPolyDataFilter don't
work for the cube?
