Hi Robert,
I am using the 2.6.1 that's why I didn't found stats code.
For the moment, I just copy the code from 2.8 concerning camera stats
(visible vertices, ...) but it does not work correctly :
In the StatsHandler, in the case of camera stats, there is :
> for(osgViewer::ViewerBase::Cameras::iterator itr = cameras.begin();
> itr != cameras.end();
> ++itr)
> {
> osg::Stats* stats = _camera->getStats();
> if (stats)
> {
> stats->collectStats("scene",true);
> }
> }
>
But when I do _camera->getStats(), I get NULL ... so the stats do not
contain anything so I have no stats on the screen.
I didn't found if there is an other initialization or something to do on
camera to get/compute the stats ... my Handler is very close to the
StatsHandler of the 2.8...
What do I miss ?
Thanks a lot.
Regards,
Vincent
