convert vtkpolydata to occt dataType

Hello Administrator. Thank you for your reply.

I want to apply the occt algorithm again to the resulting data from the vtk algorithm. then, i will display mesh data by using ivtk

        TopoDS_Shape box1 = boxMaker1.Shape();

        IVtkOCC_Shape::Handle aShapeImpl = new IVtkOCC_Shape(box1);

        vtkSmartPointer<IVtkTools_ShapeDataSource> DS = vtkSmartPointer<IVtkTools_ShapeDataSource>::New();

        DS->SetShape(aShapeImpl);

        vtkSmartPointer<vtkPolyDataMapper> mapper = vtkSmartPointer<vtkPolyDataMapper>::New();

        mapper->SetInputConnection(DS->GetOutputPort());

        vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();

        actor->SetMapper(mapper);

        actor->GetProperty()->SetColor(colorRGB(0, 0, 255));

        actor->GetProperty()->SetOpacity(0.7);

        mpMainRenderer->GetRenderer()->AddActor(actor);

The source is perfectly work. so i just want to know how convert vtkpolydata to TopoDS_Shape or other occt dataType.

i found any source.

        IVtkOCC_Shape::Handle occShape = IVtkTools_ShapeObject::GetOccShape(actor); // actor is vtkActor​ instance.

        vtkSmartPointer<IVtkTools_ShapeDataSource> DS = vtkSmartPointer<IVtkTools_ShapeDataSource>::New();

        DS->SetShape(occShape);

but. it didn't work. // TKIVTK.dll error.

Is there any way?

Best regards,
