Usage

ParaView

C++

#include <tscTriSurfaceCutter.h>

vtkNew<tscTriSurfaceCutter> cutter;

// xxx: filter that outputs a vtkPolyData
cutter->SetInputConnection(0, xxx->GetOutputPort());
// yyy: filter that outputs a vtkPolyData
cutter->SetInputConnection(1, yyy->GetOutputPort());

cutter->Update();
cutMesh = cutter->GetOutput(0); 

Python

import tsc
...
cutter = tsc.tscTriSurfaceCutter()
cutter.SetInputConnection(triangulation.GetOutputPort())
cutter.SetLoopsConnection(1, loops.GetOutputPort())
