Hi,
The masks was a good idea, and there is a little bit improvement but not
enough in my case...
I'm still trying to make some improvement using them, but without the
expected success.
So if you have any other idea... please share it !
Thanks.
Regards,
Vincent

Whilst I haven't used osgWidget, I know we had a similar performance
issue with picking when we didn't use an appropriate node mask for
picking so that only the pickable objects in the scene are considered.
I wonder if osgWidget has implemented one in it's pick handler.

Kim.

Hi all,
I'm currently trying to find a performance improvement in
osgWidget due to some lag we have in our application : We use
osgWidget to manage some things at runtime, but we realized that
performances were dropping in big scenes.
Using profiler & co, I found that the
osgWidget::WindowManager::pickAtXY function is very expensive in
time...
Here is my question : this method is called on every event,
specially on mouse move and click, event if the mouse is not over
Widgets... Is there any reason to make this ? Can this be
improved, for example doing it only if the mouse is over the
widgets, using a simple XY square test...
Thanks for your answers.
Regards,
Vincent.
