I think this is a rendering issue and not an interpolation issue. From the 2d plot you can see that it's properly interpolating the values. I think the quadrilateral is getting rendered as 2 triangles in which case the diagonal values appear to be constant since the 2 end points are at the same value.<br>

Hello, paraview users<br>
<br>
I draw the file “Sample_inter.vtk” on ParaView. (ref:attached file)<br>
I chose “Gouraud” in Interpolation option.<br>
The contor picture doesn’t seem to be interpolated by 4 points.<br>
However,the graph which is made by PlotOverLine shows the gradation of<br>
4 points scalar.<br>
Why are they different?<br>
Does anyone know this problem?<br>
How can I make contour picture interpolated by Gouraud ?<br>
<br>
I look forward to your reply to my inquiry<br>
<br>
