 I am Cutting a mesh using vtkClipClosedSurface but it is always keeping one<br>
part and i need get the other part which is cropped ,my code is here below<br>
<br>
quad = vtk.vtkSTLReader()<br>
quad.SetFileName(vtkFile)<br>
quad.Update()<br>
mesh = quad.GetOutput()<br>
<br>
clipPlane = vtk.vtkPlane()<br>
clipPlane.SetOrigin(0,0,-54.<wbr>3772147817)<br>
clipPlane.SetNormal(0,0,1)<br>
<br>
centerFilter = vtk.vtkCenterOfMass()<br>
centerFilter.SetInput(mesh)<br>
centerFilter.<wbr>SetUseScalarsAsWeights(False)<br>
centerFilter.Update()<br>
center = centerFilter.GetCenter()<br>
print center<br>
<br>
transform = vtk.vtkTransform()<br>
transform.Translate(-center[0]<wbr>, -center[1], -center[2])<br>
transformFilter = vtk.<wbr>vtkTransformPolyDataFilter()<br>
transformFilter.SetInput(mesh)<br>
transformFilter.SetTransform(<wbr>transform)<br>
transformFilter.Update()<br>
centeredPolydata = transformFilter.GetOutput()<br>
<br>
clip = vtk.vtkClipClosedSurface()<br>
clip.SetInputConnection(<wbr>transformFilter.GetOutputPort(<wbr>))<br>
planes = vtk.vtkPlaneCollection()<br>
planes.AddItem(clipPlane)<br>
clip.SetTolerance(10e-3)<br>
clip.SetClippingPlanes(planes)<br>
clip.Update()<br>
mesh = clip.GetOutput()<br>
<br>
polyWriter = vtk.vtkSTLWriter()<br>
polyWriter.SetInput(mesh)<br>
polyWriter.SetFileName(<wbr>vtkfile)<br>
polyWriter.Write()<br>
<br>
Can any one suggest any dolution<br>
<br>
<br>
<br>
