[Insight-users] iterate through mesh

[Luis Ibanez]

Hi Sara,


If you want to iterate through the points of a mesh,
you may want to look at the code in

Insight/
  Examples/
     DataRepresentation/
        Mesh/
            PointSet2.cxx


This examples is described in the ITK Software Guide

          http://www.itk.org/ItkSoftwareGuide.pdf

in Section 4.2.2. "Getting Access to Points"
in pdf-page 83.

Essentially:

  PointsIterator  pointIterator = points->Begin();
  PointsIterator pend = points->End();
  while( pointIterator != pend )
    {
    PointType p = pointIterator.Value();   // access the point
    std::cout << p << std::endl;           // print the point
    ++pointIterator;                       // advance to next point
    }





     Regards,


             Luis
