Best pipeline for large MultiBlockDataset


I am starting to use a MultuBlockDataset. It can be composed of hundreds of point sets, lines, surfaces, and unstructured grids. I struggle to understand what pipeline I should use for this kind of data. Should I merge everything into a single PolyData, to avoid too many calls to the GPU? Should I use CompositeMapper directly?

Thanks a lot for your help


My two cents: based on what people said throughout the years, having too many actors is a bad idea. So, yes, those approaches of yours should do.



Ok, so it’s more about the number of actors than the number of mappers. I was wrong about that.
