Hi!
I have problems configuring the output of my filter, the filter is a subclass
of vtkDataSetToStructuredGrid and setting the output looks as following:
//setting the new point data
vtkSmartPointer<vtkFloatArray> new_scalars =
vtkSmartPointer<vtkFloatArray>::New();
double inPtr[numOfTuples + 1]; //pointer for casting the values actually to
double, so I can perform arithmetic operations with them
float outPtr[numOfTuples + 1];
//calculating ..
new_scalars -> SetArray(outPtr,numOfTuples,1);
output -> SetDimensions(dims);
output -> SetPoints(pts); //Now the points are set
output -> GetPointData() -> SetScalars(new_scalars);
output -> Squeeze();
dims are the dimensions of the input, which is a RectilinearGrid or a
StructuredGrid, new_scalars is a vtkFloatArray. I believe that the
"output->GetPointData() ->SetScalars(new_scalars)"-line is causing the problem,
because I get the following error messages:
Program received signal SIGSEGV, Segmentation fault.
vtkFieldData::GetActualMemorySize
at C:/ParaviewSource/ParaView3/VTK/Filtering/vtkFieldData.cxx:577
size +=this->Data[i]->GetActualMemorySize();
Backtracing, functions in vtkPVDataInformation and vtkSelfConnections are
called,
so I guess, this does not actually happen in my source code but in the
rendering pipeline. As I did not change anything in the rendering pipeline,
there must be an allocation or a call in my code with incorrect arguments, but
I do not really know where to look for the error.
Does anyone have an idea?
Thx,
NH
