[vtkusers] vtkCutter->Update doesn't update the vtkCutter->GetOutput()

[nsarrasin]

Hi all,

Why the output of vtkCutter isn't update when I do Update()?
I always get the same slice (the first to be compute).


cutter->SetInput(polydata);
cutter->SetCutFunction(plane);

for(int step=0; step<nbsteps; step++)
{
	cutter->Update();
	vtkAppendpolyData->AddInput( cutter->GetOutput() ); //here it's not updated
!!!

	//rotation of the plane normal
	vtkMatrix4x4->MultiplyPoint(plane->GetNormal(), new_normal);

	//update the plane
	plane->SetNormal(new_normal);
}

Thanks for explaining me.
