Talk:ParaQ v1.0 Features

Grouping of pipeline elements is already available through vtkMultiGroupDataGroupFilter (Filter->Group Datasets in paraview). This filter creates a multi-group (i.e. multi-block) dataset in it's output. The multi-group dataset can then be processed filters. The intermediate results are always multi-group and it is possible to extract a part out at anytime. For example, you can group cells and cells edges, clip, shrink and then extract the part corresponding to the edges. This has some limitations however. Right now, the filter can't group other multi-group (AMR, PLOT3D, output of another group filter). This is because recursive multi-group datasets are not supported in the composite pipeline and I didn't want to flatten the hierarchy. I don't think this will be too difficult to address (a few weeks of work).

Filter on/off should not be too hard either. It can be handled in the pipeline. However, the GUI has to make sure that disabling a filter does not create incompatible connections. For example, in this pipeline: image reader -> contour -> shrink polydata, the contour cannot be disable because shrink cannot operate on image data.
