[vtkusers] How can I make printf all the generated surface coordinate ?

[Amy Squillacote]

Hi Ismail,

Do something like the following after your call to cf->Update();.

vtkPoints *points = cf->GetOutput()->GetPoints();
int numPts = points->GetNumberOfPoints();
int i;
double pt[3];

for (i = 0; i < numPts; i++)
  {
    points->GetPoint(i, pt);
    printf("point %d: %f %f %f\n", i, pt[0], pt[1], pt[2]);
  }
