In vtk a polygon is just one type of cell. The vtkPolyData class can hold VTK_VERTEX'es for example, as well as VTK_POLYGONS. See <a href="http://www.vtk.org/doc/nightly/html/classvtkPolyData.html">http://www.vtk.org/doc/nightly/html/classvtkPolyData.html
</a> or the books for more information. Use GetPoly's to get a list of only the polygonal cells, then use getcellpoints and getcellneighbors on each cell id from that list.<br><br>cheers<br>Dave DeMarle<br><br><br><div>

<div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">Hi! In plain English, what is (are) the difference(s) between cells
and polygons? And if I'm trying to loop over the triangles (are these cells or polygons?) created by vtkDelaunay2D from
numbered points to get the point numbers of each triangle's vertices,
as well as each triangle's neighboring triangle objects, which vtkPolyData method
do I use for each of these tasks? Thanks!<br><br>DG<div> </div><a rel="nofollow" href="http://www.python.org" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">Python: It just works!</a><div><span class="ad">
