Hi Michael,

Current implementation is maintained in osgRecipes (
https://github.com/xarray/osgRecipes), and some snapshots are shared in the
mail-list a few days ago using both VDSM and the compositor.

<br>
Did you ever get a chance to work up an example showing something like<br>
this? I&#39;ve been trying to get it to work using a modified blur-x/blur-y=
<br>
approach from osgPPU, but have had no success.<br>
