<br>
I really can't tell why my code is not gernerating the iso-surface.<br>
I have a structured grid (sGrid) filled with scalars.<br>
<br>
I call the contour filter<br>
<br>
            vtkContourFilter *scalarIsoSurface =
vtkContourFilter::New();<br>
            scalarIsoSurface-&gt;SetInput(sGrid);<br>
            scalarIsoSurface-&gt;GenerateValues(0,0.1);<br>
<br>
Compute the normal<br>
<br>
            vtkPolyDataNormals *sGridPolyDataNormal =
vtkPolyDataNormals::New();<br>
           
sGridPolyDataNormal-&gt;SetInput(scalarIsoSurface-&gt;GetOutput());<br>
<br>
Put them into a poly data mapper<br>
<br>
            vtkPolyDataMapper *scalarIsoSurfaceMapper =
vtkPolyDataMapper::New();<br>
           
scalarIsoSurfaceMapper-&gt;SetInput(sGridPolyDataNormal-&gt;GetOutput());<br>
<br>
and into an actor<br>
<br>
            vtkActor *scalarIsoSurfaceActor = vtkActor::New();<br>
            scalarIsoSurfaceActor-&gt;SetMapper(scalarIsoSurfaceMapper);<br>
<br>
which is passed on to the scene<br>
<br>
            ren1-&gt;AddActor(scalarIsoSurfaceActor);<br>
<br>
and NOTHING happens.<br>
<br>
Any ideas what I have missed, or whats wrong?<br>
<br>
