[vtkusers] Test

[Yang, Jinzhong]

Thank you all for your reply. So it works, great! :)

 

Here is my question.

 

I have an enclosed surface (in vtkPolyData format) and I use vtkClipPolyData
to clip the surface in a smaller volume. After the clip, I get a surface
that is not closed - it becomes open at the cutting plane. I wonder if there
is any simple method in VTK to make the new surface closed again - maybe
just put some points on the cutting plane and compose some triangular cells.

 

Here is the source code that I used to clip the surface.

 

roi_start[3] is the x,y,z values of the starting point of ROI, roi_end[3]
are the x,y,z values of the ending point of ROI.

meshProcessor->GetOutputPort() is an enclosed surface.

 

  double roi_start[3], roi_end[3];

 

  vtkPlanes* BoundingBox = vtkPlanes::New();

  BoundingBox->SetBounds(roi_start[0], roi_end[0], roi_start[1], roi_end[1],
roi_start[2], roi_end[2]);

 

  vtkClipPolyData * clipper = vtkClipPolyData::New();

    

  clipper->SetInputConnection(meshProcessor->GetOutputPort());

  clipper->SetClipFunction(BoundingBox);

  clipper->InsideOutOn();

  clipper->Update();

 

Thanks,
