Hi!
I´m writing a filter and I want to perform arithmetic operations, i.e. "+="
with the scalar data associated to each point of my grid. So I get the Point
Data from the input file:
void vtkHorizontalAverage::Execute()
{vtkStructuredGrid *input = this->GetInput();
vtkStructuredGrid *output = this->GetOutput();
vtkPointData *inPtr = input->GetPointData();
vtkPointData *outPtr = output->GetPointData();
...
here and now I want to apply the += operator, but I have no idea how to cast my
vtkPointData - object, since I do not really know where to fit the cast
operator in, to the vtkPointData class or to the vtkDataArray..
I could also use a reinterpretcast, but I´m not sure if the format of the data
in vtkPointData is double or float..
So, any help would be apreciated!
thx,
NH
