你好阿尔赛斯,
(Next time you may have more luck sending your VTK questions to <
vtkusers at vtk.org>.) You can do something like this:
double pt[3];
vtkIdType npts, *pts;
int numPts = myPolyData->GetNumberOfPoints();
for (int i=0; i < numPts; i++)
{
myPolyData->GetPoint(m,pt);
std::cout << "point with index " << i << ": (" << pt[0] << " " << pt[1] <<
" " << pt[2] << ")" << std::endl;
}
myPolyData->GetCells()->InitTraversal();
while (myPolyData->GetCells()->GetNextCell(npts,pts))
{
std::cout << "cell has " << npts << " points with indices:";
for (int i=0; i < npts; i++)
{
std::cout << " " << pts[i];
}
std::cout << std::endl;
}
You might need to try and compile this code as I have just typed it into
GMail without compiling.
Regards,
Sylvain
