ParaView/Custom Filters
ParaView is a pipeline-based framework: user loads in data and then applies a bunch of filters forming a pipeline to further process and then possibly render or save the result. Often times users find themselves applying the same set of filters with some minor parameter tweaks for a few filters in the pipeline to different datasets. With what we call custom filters, it's possible for the user to combine the pipeline into a single filter while exposing a set a properties from the internal filters that need tweaking. Additionally, the user can then share his custom filter's with other users.
