looping pipeline
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
In VTK 4.2, it was possible to create a loop in an execution pipeline. However in VTK 5.0, creating a looping pipeline causes VTK to go into an infinite loop. For example, set up a pipeline like the following initially and render.
vtkSphereSource -> vtkElevationFilter -> vtkShrinkFilter -> vtkDataSetMapper ...
Then set the input to the vtkElevationFilter to be the output of the vtkShrinkFilter. Render repeatedly; you should see the shrink further with each successive render. See the attached .cxx file for an example that does this.
