Yup, that was the issue, it was a simple matter of changing the coordinates of my grid to floating point instead of integer.

I recall it had to do with the type of the points being specified as an integral type. The change between 3 and 4 was that interpolation for the isocontours is now performed with the precision available in the point type, so if your point type is an integral value, you'll get this chunky result. Try changing your point type in your data file to float or double. Hope that helps, Cory On Wed, Apr 15, 2015 at 4:09 PM, Greenwood, Michael <[email protected]<mailto:[email protected]>> wrote: 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.

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

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?
