[vtkusers] Execute filter asynchronous

[Jim Peterson]

Jan,
The vtkExecutionScheduler has this comment in the header file. Perhaps 
the referenced papers or the authors can shed some light on your issue.

 This is part of the Parallel Dataflow System originally developed by
 Huy T. Vo and Claudio T. Silva. For more information, see:

It looks like this parallel capability was added in 2009.  The 
Examples\ParallelProcessing\Generic\Cxx
directory does appear to have some examples dating from 2005 of some 
subdivisions of pipeline processing to multi-thread
by discrete functions. I am not sure whether you could apply that to 
your problem.

Good luck,
Hope that helps,
Jim

I'd like to execute (long running) visualizations in the simulation thread and then do the final rendering (of the actors) in the UI thread. Is this possible and when can you point me to an example code or give be a hint to google for?
