[Paraview] questions re VTK-formatted file

[Randy Heiland]

Pat,

Thanks for the tips.  Sure enough, the clean-to-grid filter worked (seems odd though, as the contour filter would presumably use a slower alg on an unstruct grid).

Regarding the "Convert to" 2D/3D views, when I tried it on that example, it seemed to clear the views and I wasn't sure how to recover them.  But I'll keep playing.

Paraview's colormap editor can be a bit touchy, and it's easy to accidentally add extra points.  When I tried your example data, it correctly colored the point with scalar value 1 using the default color map.

After you open your data, you can right-click the area above the render view and choose "Covert To" in the context menu to convert the 2D view to a 3D view.
