Hi Gianni,<br>
<br>
I solved it for me by deriving the viewer class and setting a <br>
local variable "needsUpdate" with any mod of the sceene.<br>
This works pretty good.<br>

<pre wrap="">Hi All,
can anybody tell me please if there is a way to know if the OSG scene has been modified (i.e. node added or removed) so that I can check if osgViewer::ViewerBase::frame() must be called in a setRunFrameScheme(ON_DEMAND) case?
Regards
Gianni
