2DArray

VTKExamples/Cxx/Utilities/2DArray

Description

This example creates a 5x5 2D array and sets the (4,4) (zero based indexing, of course) entry to 5.0. Then it outputs this value to demonstrate accessing.

Code

2DArray.cxx

#include <vtkSmartPointer.h>
#include <vtkDenseArray.h>

int main(int, char *[])
{
  vtkSmartPointer<vtkDenseArray<double> > array = 
    vtkSmartPointer<vtkDenseArray<double> >::New();

  array->Resize(5,5);

  array->SetValue(4,4, 5.0);

  std::cout << array->GetValue(4,4) << std::endl;

  return EXIT_SUCCESS;
}
