Graphics/Testing/Tcl/TestRuledSurface*.tcl<br><br>The difference from the tests is that you need to set "ClosedSurfaceOn()". <br><br>Also, if the number of points in each of the contours is different or not in correspondance, you'll want to resample the contours by setting "SetRuledModeToResample()".<br>
<br>And there are ways to do this without using vtkRuledSurfaceFilter as well... <br><br>You could rasterize the contours (vtkPolygon::PointInPolygon), treat the result as an image, run an AntiAlias filter (ITK) and then triangulate by generating an isosurface with marching cubes.<br>
