Hi VTK users,<br>
<br>
We sometimes have very large models displayed using a
<title>Snippet</title>
vtkUnstructuredGrid+vtkActor+vtkDataSetMapper.<br>
I'd like to enable LOD so that I can get a minimum level of
performance when doing dynamic rotations/pans/zooms.<br>
Ideally, it would do like ParaView and reduce the number of
triangles using some kind of decimation of the data.<br>
<br>
I tried replacing vtkActor with vtkQuadricLODActor, replacing
vtkDataSetMapper with vtkPolyDataSetMapper.<br>
The problem is that vtkUnstructuredGrid isn't derived from
vtkPolyData.<br>
<br>
How can I finish connecting all the pieces? Or is there a
different/better way?<br>
<br>
Thanks.<br>
