Hi,
could you please tell me, how to get the point data of the poly data.
i am trying to do something like that,
vtkSmartPointer<vtkPolyData> polydata =
vtkPolyData::SafeDownCast(sampleVolume->GetOutput());
// Get the number of points in the polydata
vtkIdType idNumPointsInFile = polydata->GetNumberOfPoints();
cout<< " number of points " << idNumPointsInFile;
vtkSmartPointer<vtkDoubleArray> array =
vtkSmartPointer<vtkDoubleArray>::New();
array->SetName("Distances");
vtkDoubleArray::SafeDownCast(polydata->GetPointData()->GetArray("Distances"));
if(array)
{
for(int i = 0; i < idNumPointsInFile; i++)
{
std::cout << "Got array." << std::endl;
double dist;
* dist = array->GetValue(i); // here i am getting error*
//if the array held arrays instead of scalars, you would use this:
/* double location[3];
array->GetTupleValue(i, location);
std::cout << "Location: " << location[0] << "," << location[1] << "," <<
location[2] << std::endl;
*/
cout<< "where is the problem";
std::cout << "Distance: " << dist << std::endl;
}
}//end if(array)
else
{
std::cout << "no array." << std::endl;
}
return EXIT_SUCCESS;
could you please tell me, why i am getting error at this position?
Looking forward your reply soon.
