[vtkusers] Infovis: Parallel coordinates view/rep/interact example?

[Eric E. Monson]

Hey again David,

A possible bug I noticed while I was playing around with different parallel coordinated view options:

If I use SetBrushModeToAngle() or SetBrushModeToFunction() it seems to work okay, but I get a bunch of errors in my python console like this while I'm interacting with the view, changing the line angles (repeated over and over again):

ERROR: In /home/emonson/Programming/VTK_cvs/VTK/Filtering/vtkActor2D.cxx, line 126
vtkActor2D (0x1068dc0): vtkActor2D::Render - No mapper set

ERROR: In /home/emonson/Programming/VTK_cvs/VTK/Filtering/vtkActor2D.cxx, line 171
vtkActor2D (0x1068dc0): vtkActor2D::HasTranslucentPolygonalGeometry - No mapper set

ERROR: In /home/emonson/Programming/VTK_cvs/VTK/Filtering/vtkActor2D.cxx, line 100
vtkActor2D (0x1068dc0): vtkActor2D::Render - No mapper set

I don't see it when I use "lasso" selection. It shows up on both my OS X 10.6.2 and Ubuntu 9.10 systems, both using CVS VTK built with CMake 2.9.20100113 and 2.6-patch 4 respectively.

Talk to you later,
-Eric

Is there anyone who has been working on the development that could pass along an example of how to put it all together (even if it's not a very polished) so I could get started testing it a little more quickly?
