As far as I understand, there just have to be _some_ scalars associated with the data because to evaluate the implicit function the algorithm needs to do interpolation within the cells. I just used elevation because it was quick and easy to hook up.<div><br></div><div>-Eric</div><div><br><div><blockquote type="cite"><font class="Apple-style-span" color="#000000"><br></font><div>Here it is in c++:</div><div><a href="http://www.vtk.org/Wiki/VTK/Examples/ImplicitDataSet">http://www.vtk.org/Wiki/VTK/Examples/ImplicitDataSet</a></div><div><br>
</div><div>The higher the resolution of your model, the less these artifacts are noticeable. </div><div><br></div><div>Eric - can you explain in a bit more detail what the scalars from the elevation filter do? For example, could we just use all 1's in an array in PointData?</div>
