[vtkusers] Get Tuple of vtkDataArray

[Bayliss, Chris (Chicago)]

I am trying to create a two column, 5 row dataset with vtkDataArray.
However, when I try to access the data in the second column, I get some
garble like: 05BCBE88.  Am I accessing the data incorrectly?  The data
from the first column is fine.

 

vtkDoubleArray * distvals = vtkDoubleArray::New();

distvals->SetNumberOfComponents(2);

distvals->SetName("distvals");

 

double dist = sqrt((points[0]-pathpoint[0])*(points[0]-pathpoint[0]) +
(points[1]-pathpoint[1])*(points[1]-pathpoint[1]) +
(points[2]-pathpoint[2])*(points[2]-pathpoint[2]));

 

distvals->InsertTuple2(i, dist, i);

 

for (vtkIdType c=0 ; c < 5 ; c++)

{

std::cout << "list: " << distvals->GetTuple1(c) << " , " <<
distvals->GetTuple2(c) << std::endl;

}

 

Why does GetTuple2(c) not return the data that was entered?  Is this a
simple conversion issue?  If so how would I convert that number for
output?

 

Thanks,

 

Chris
