[Paraview] [EXT] Re: How to find the distance to nearest node for each node in MultiBlockDataset

[Dennis Conklin]

Utkarsh,

Thanks very much, that routine is several orders of magnitude faster than my kludge.

FYI,  I read chapters 13 and 14 of the User's Guide and reviewed several blog posts and didn't really see anything about vtkAppendFilter or VTKNonMergingPointLocator.   I would suggest that when you have a minute this would be an excellent example to add to the wiki as it shows some things that are not really shown anywhere else.

I'm very happy to report that based on the results of this filter we are able to create a Quality metric for our cord meshes that is proving very valuable.

Thanks again for your help

Dennis

Dennis,

The ParaView Guide chapter 14 and this blog post
(http://kitware.com/blog/home/post/723) talks about how arrays on composite datasets are treated. Anycase, attached is a script that's better at finding the closest point and then computing the distance.
It uses a PointLocator to find the closest point.
