[vtkusers] Pipelines and high-level control (was GUI for VTK)

[Chris Myers]

Related to this point raised here is something that I think is
important, but which seems to have been lacking in this thread on a
VTK GUI (although I admit that I haven't read every last bit of the
discussion).

Any VTK GUI would be considerably aided, it would seem, by programming
language support for pipelines (as well as other collections of VTK
objects).  I've always found it a bit strange that VTK is so richly
structured in a hierarchial fashion, but that the scripts and programs
used to drive it are so flat (and sometimes hard to follow).  I've
played around a little bit (from within Python) with building pipeline
objects, and other facades on top of the core VTK libraries (to bundle
up collections of objects and present simpler interfaces), although
I haven't yet gotten as far with that as I would like.

As I said, having abstractions for VTK pipelines would be useful for
building GUIs as well as other higher-level control framework, whether
graphical in nature or not.  I am wondering whether anyone else has
developed any such code, or has thought about such issues.
