Use vtkHardwareSelector, it is a more recent implementation of visible<br>
surface selection. It will give you cells if you ask it to for<br>
instance. See: <a href="http://www.vtk.org/doc/nightly/html/classvtkHardwareSelector.html" target="_blank">http://www.vtk.org/doc/nightly/html/classvtkHardwareSelector.html</a><br>

I think the only thing that can be done about not needing a monitor is<br>
to use an offscreen rendering context (osmesa for example). Screen<br>
space operations like visible surface selection get too much from the<br>
infrastructure that VTK's display pipeline (and openGL underneath)<br>
provide to make removing them practical.</blockquote><div><br></div><div>If you figure out how to get it to work and could fix this example:</div><a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Broken/Filtering/ExtractVisibleCells">http://www.vtk.org/Wiki/VTK/Examples/Cxx/Broken/Filtering/ExtractVisibleCells</a><br clear="all">
