<DIV><FONT face=Arial size=2>Hi! Here's the situation:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>vtkLineSource
*line->vtkLineSource::New();</FONT></DIV>
<DIV><FONT face=Arial size=2>vtkPolyData
*polydata->vtkPolyData::New();</FONT></DIV>
<DIV><FONT face=Arial size=2>...</FONT></DIV>
<DIV><FONT face=Arial size=2>...</FONT></DIV>
<DIV><FONT face=Arial size=2>polydata=line->GetOutput();</FONT></DIV>
<DIV><FONT face=Arial size=2>int nofc;</FONT></DIV>
<DIV><FONT face=Arial size=2>nofc=polydata->GetNumberOfCells();</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1st) Why "GetNumberOfCells()" returns 0
? ("line" it's just a straight line).</FONT></DIV>
<DIV><FONT face=Arial size=2>2st) polydata=line->GetOutput(): Is it the
correct way to copy vtkPolyData? I've tried ShallowCopy() and DeepCopy(), but
nothing happened.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm using vtk 5.0, thanks
everybody!!</FONT></DIV></BODY></HTML>
