[vtkusers] mesh subdivision

[NsPx]

Hi all,

I would like to decimate a mesh using a criterion (let's say "edge 
length <=1").

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.

Mainly, I can't pass a vtkPolyData, I have to use it cell (triangle) by 
cell ? How can I use the callabacks ?
Can someone provide some example ?

Thanks by 
advance.|<http://www.vtk.org/doc/nightly/html/classvtkStreamingTessellator.html>|
