</div></div>You could label the three parts by adding an array to the point or<br>
cell data, something like this:<br>
<a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/MiscCellData" target="_blank">http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/MiscCellData</a><br>
<br>
I don't know how you intend to determine the three regions though.<br>
