[vtkusers] Error porting from VTK 5.10 to VTK 6.1

[francesco.argese]

Hello,

I'm having problems trying to port an application from VTK 5.10 to VTK 6.1.

The application is a simple LSDyna reader which loads the frames of the
animation and stores them in a vector of actors; then it uses them for a
conversion.

The only modification needed to compile the code with VTK 6.1 is the
following one:
#ifdef __VTK_5__
	mapper.at(k)->SetInput(myData.at(k).GetPointer());
#else
	mapper.at(k)->SetInputData(myData.at(k).GetPointer());
#endif

The error at runtime is generated when I call SetMapper function.

The entire code with a note on the runtime error is below.

What could be the problem?

Francesco


---------------------------- CODE  (BEGIN)
-----------------------------------------
int main(int argc, char **argv)
{
	// 0) Parse command line arguments. First argument is path of dir
containing LS-DYNA files
	if(argc != 2)
	{
		std::cout << "Usage: " << argv[0] << " directory path" << std::endl;
		return EXIT_FAILURE;
	}
	std::string dir= argv[1]; // Save command-line argument to dir variable

	// 1) Use lsDyna reader to read file from lsDyna output
	vtkSmartPointer<vtkLSDynaReader> reader =
vtkSmartPointer<vtkLSDynaReader>::New();
	reader->SetFileName(dir.c_str());
	reader->Update();

	// Extract a vector of actors from lsDynaReader
	std::vector<std::vector<vtkSmartPointer<vtkActor>>> vectorOfFrames;
// every frame is a vector of actor
	for(unsigned int i = 0; i < reader->GetNumberOfTimeSteps(); i++) // loop
over frames
	{
		// Set frame number and update
		reader->SetTimeStep(i);
		reader->Update();

		vtkMultiBlockDataSet* mbds =  reader->GetOutput();

		std::vector<vtkSmartPointer<vtkDataSetMapper>> mapper;
		std::vector<vtkSmartPointer<vtkDataSet>> myData;

		std::vector<vtkSmartPointer<vtkActor>> actorsForThisFrame;

		for(unsigned int k=0; k<=mbds->GetNumberOfBlocks(); k++)
		{
			// Define a new mapper (process object to be related to the new vtkActor)
and add it to vector of mappers
			vtkSmartPointer<vtkDataSetMapper> newMapper =
vtkSmartPointer<vtkDataSetMapper>::New();
			// newMapper->SetScalarRange(0, 10);
			mapper.push_back(newMapper);

			// Take vtkDataSet extracted from multiBlockDataset extracted from
lsDynaReader
			myData.push_back((vtkDataSet *)mbds->GetBlock(k));
			
			// Set dataset inserted as last mapper input 
			#ifdef __VTK_5__
				mapper.at(k)->SetInput(myData.at(k).GetPointer());
			#else
				mapper.at(k)->SetInputData(myData.at(k).GetPointer());
			#endif
			
			// add a new vtkactor to vector of vtkActors
			actorsForThisFrame.push_back(vtkSmartPointer<vtkActor>::New());

			// Set mapper created as mapper of the vtkActor
			actorsForThisFrame.at(k)->SetMapper(mapper.at(k).GetPointer()); // Here
there is the run time error!!!
		}

		vectorOfFrames.push_back(actorsForThisFrame);
	}
