[vtk-developers] vtkDataArray::GetTuple(int i, double[3])

[David Doria]

After a brief chat with Darshan on the users list, we would like to propose
adding a function to vtkDataArray:

void vtkDataArray::GetTuple(int i, double[3])

It would work the same way that

double vtkDataArray::GetComponent(int,int)

currently works in the sense that no matter the underlying data type it
would return a double. The idea is to be able to get a double array of a
tuple from either a vtkDoubleArray or a vtkFloatArray.

Thoughts?

Thanks,

David
