<font size="-1"><font face="Tahoma">Hi all,<br>
<br>
I would like to decimate a mesh using a criterion (let's say
"edge length <=1"). <br>
<br>
By searching through the documentation, I find the only way is
to use vtkStreamingTesselator coupled with
vtkEdgeSubdivisionCriterion but I don't really understant how to
use it. <br>
<br>
Mainly, I can't pass a vtkPolyData, I have to use it cell
(triangle) by cell ? How can I use the callabacks ?<br>
Can someone provide some example ?<br>
<br>
Thanks by advance.</font></font></div></blockquote><div><br></div>There are a few subdivision techniques available: <a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Meshes/Subdivision">http://www.vtk.org/Wiki/VTK/Examples/Cxx/Meshes/Subdivision</a><br clear="all">
