Hi David and all,
I am writing a reader plugin for ParaView. A test program without the VTK
wrapping approves that I can get all the header (metadata) and grid data
correctly. However, when I following the examples posted in
http://www.vtk.org/Wiki/ParaView/Examples/Plugins/Reader
http://www.kitware.com/products/html/WritingAParaViewReaderPlug-in.html
and vtkStructuredGridReader.h/.cxx
I got confused. Shall I subclass vtkStructuredGridAlgorithm or
vtkStructuredGridReader? What are the differences? With minor differences in
the code, i.e. defining char* FileName, I have both scenarios built fine.
Let's say, we are subclassing vtkStructuredGridAlgorithm for now on. After I
populate values as the following
int vtkGRIB2Reader::RequestInformation(vtkInformation* vtkNotUsed(request),
vtkInformationVector**
vtkNotUsed(inputVector),
vtkInformationVector *outputVector)
{
...
vtkInformation* outInfo = outputVector->GetInformationObject(0);
outInfo->Set(vtkStreamingDemandDrivenPipeline::WHOLE_EXTENT(), ext, 6);
outInfo->Set(vtkDataObject::SPACING(), this->Spacing, 3);
outInfo->Set(vtkDataObject::ORIGIN(), this->Origin, 3);
return 1;
}
In ParaView Object Inspector / Information widget, I did not see any update in
all the fields except Statistics / Type: Structured (Curvilinear) Grid. Would
you please help me? Did I populate outInof in the wrong place? Thanks a lot.
Best,
xunlei
