<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>There is something wonky with whatever service you are using to post your files. The first several times I tried accessing them, I just got some web pages with a bunch of advertisements in French (which I cannot read). After several attempts, I finally got the files.<BR>
<BR>
When I run the contour filter with the default isovalue for each input, I get roughly the same result. The major difference is that normals are automatically generated for image inputs but not for unstructured grids. Thus, the output for the unstructured grid resorts to flat shading, which makes it look like it has sharper edges even though the polygons are the same. If you run the normals filter on the ugrid output (turning off splitting), you will see the result looks similar. You can also try turning <I>off</I> the Compute Normals feature for the <I>image</I> input. With the normals gone, you will see that the result is the same.<BR>
<BR>
By default, the contour filter does not compute or pass scalar values for image data. If you click on the Compute Scalars checkbox, you should see them again. The contour filter always computes scalar values for unstructured grids. I’m not sure why the two are different.<BR>
