[Paraview] Contours of unstructured grid paraview 3 vs paraview 4

[Greenwood, Michael]

The data file is being held in moderation since its larger size, let me see if I can find a place to store it and send a link.

It seems that in paraview 3 it would interpolate inside the cell between the mesh points when building the polymesh for the contour and now it is snapping the interpolation to nearest grid point of my unstructured mesh.

Very strange. I can't recall a change that can cause this. Do you have a dataset that we can reproduce this with?

Best,

Hi I’ve upgraded to paraview 4 and now when building contours of my 3D unstructured grid, the contours are pixelated.  This was not the case in 3, and when you look at a slice of the contour overlayed with a slice of the volume data it is obvious that the contour in paraview 4 seems to be “hugging” the boundaries of my mesh instead of interpolating through it.  How can I get my nice smooth contours I had in version 3?

Thanks
