[Paraview] Tiled Quadric Clustering

[Jeshua Lacock]

Greetings,

I have tiled my DEMs and saved them to VTK which I am opening into  
ParaView.

I then run the Delaunay2D filter to generate polygons from the point  
data.

I need to simplify the data using a quadric cluster algorithm (or  
similar). I am checking the "Use Feature Edges" option, but I am  
seeing gaps in the connecting tiles, see:

In other words, the feature edges are not being completely honored.  
The data for the edge columns and rows are identical from one tile to  
the next.

Does anyone know a filter or setting that I can run to fix this? I  
need my tiles to be seamless, and I am really hoping that can use  
ParaView for the job. It is a beautiful program, I have the process  
automated with Python, and it seems so close to being exactly what I  
need.

I greatly appreciate any advice, tips or pointers.


Thank you,
