<div>Hi, Steffan,</div><div><br></div>You need add points to the voronoiDiagram explicitly so far.

<div> }</div></div><div><br></div>The output voronoi.vtk will be correct.</div><div><br></div><div><br></div><div><br></div><div>wanlin</div><div><br><div class="gmail_quote">On Tue, Jun 28, 2011 at 12:34 PM, Steffan <span dir="ltr"><<a href="mailto:ulysse.rigaud@gmail.com">ulysse.rigaud@gmail.com</a>></span> wrote:<br>

I think there is a different data structure between Mesh and VoronoiDiagram2D.</div><div>By using VoronoiDiagram2D::Superclass (which is Mesh) as template value for VTKPolyDataWriter, we are writing only the data structure in common between Mesh and VoronoiDiagram2D.</div>
