Surface Selection: prefer global id based selections if data has global ids
Steps:
- Open can.ex2, Apply
- Select a few cells and then create Extract Selection filter. From the Properties panel we can tell that's it simply an ID based selection.
While this is okay, if we created a global id based selection instead (when global ids are present), the selection will work far better and more robust in case of state save/restore if the state was loaded on a parallel pvserver with different set of ranks, for example.
