Hey Mike, Hopefully someone else has a "real" filter that will do this, but in the meantime I think you can do what you want with a Python Programmable Filter. Set the output to the type you want, and put something like this in the script:
pdi = self.GetInputDataObject(0,0) block0 = pdi.GetBlock(0) pdo = self.GetOutputDataObject(0) pdo.ShallowCopy(block0) -Eric ------------------------------------------------------ Eric E Monson Duke Visualization Technology Group On Apr 29, 2010, at 10:53 AM, Michael Jackson wrote: > Is there a pipeline that would allow me to extract a block from a MultiBlock > data set and end up with the "native type" of vtk object that the block > represents? > > I have a custom reader that reads data from an HDF5 file and outputs > vtkMultiBlockDataset.
