Re: [osg-users] CompositeViewer::removeView crashes
Hi Nick, Would it be possible to modify one of the existing OSG examples to add a unit test for this problem. Switching on a problem subgraph via an command line option would be perfect. Once others can recreate the issue we'll be able to dig into why it's happening. Cheers, Robert.

Re: [osg-users] CompositeViewer::removeView crashes
I figured out the conditions. In the scene, I have a model that has cameras (pre-render) attached to some portion of the models via textures. When I load that model, then it hangs. Without this model, everything looks just fine Nick http://www.linkedin.com/in/tnick On Wed, Dec 23, 2009 at 7:23 PM, Trajce Nikolov wrote: > here is the code snippet > > mLib->getViewer()->stopThreading(); > mLib->getViewer()->removeView(view); > mLib->getViewer()->startThreading(); > > it is called before viewer->frame() > > let me investigate this a bit more.

Re: [osg-users] CompositeViewer::removeView crashes
here is the code snippet mLib->getViewer()->stopThreading(); mLib->getViewer()->removeView(view); mLib->getViewer()->startThreading(); it is called before viewer->frame() let me investigate this a bit more.

Hi Robert,
now it hangs at
// dispatch the rendering threads
if (_startRenderingBarrier.valid()) _startRenderingBarrier->block();
the same method

Re: [osg-users] CompositeViewer::removeView crashes
Hi Nick,
Try calling stopThreading() before you remove the view, and
startThreading() after you've done it.

Re: [osg-users] CompositeViewer::removeView crashes
Hi Robert,
now I did it outside frame. Id doesnt crash anymore ... but, it hangs at
_endDynamicDrawBlock->block();
void ViewerBase::renderingTraversals()
after view removal
I have composite viewer
with
setThreadingModel(osgViewer::CompositeViewer::CullThreadPerCameraDrawThreadPerContext);
any ideas ?

Re: [osg-users] CompositeViewer::removeView crashes
Hi Nick,
How are you removing the view? From an event handler from within the
view? If so then this will crash as you'll be deleting the object you
are doing the work from.
The right way remove a view is outside of frame().
