Hi all, Is there a way to extract a block from a vtkMultiBlockDataSet in Paraview without using Extract Block > Merge Blocks (which converts the data in an Unstructured Grid)?
For example, I import EnSight data, which is read in as a vtkMultiBlockDataSet with a single vtkStructuredGrid block. A bug prevents from me from visualizing multi-block dataset with volume rendering, so it would be nice to extract the structured grid data. I've tried to do so as follows in a Programmable Filter: mbi = self.GetInputDataObject(0,0) sgo = self.GetStructuredGridOutput() sgo.DeepCopy(mbi.GetBlock(0)) However, when I apply this filter, there is no output. There is no visible object in the render window and there is nothing to inspect in Spreadsheet View. But if I print sgo in the Programmable Filter, all the usual vtkDataObject information is there. What is happening here, and can I get around it? Thanks, Evan Kao
