Hi,
I am trying to implement a mechanism by which selected objects in my scene are
highlighted. Searching the forum I found a reference to the Outline effect (an
implementation of osgFX::Effect) on Ulrich Hertlein's web site
(http://www.sandbox.de/osg/), and I have attempted to integrate it into our app
- however, most of the time, whenever the object which is outlined first comes
into view, the app crashes in osg::NodeCallback::traverse, because the
_nestedCallback member is corrupted. This is on Windows Vista-64, running OSG
2.6.1 built with Visual Studio 2008, in Debug mode. We are running OSG
multithreaded, and all my code setting up the effect is called from
osg::NodeCallback::operator() on the render thread. The general flow is as
follows:
Code:
osg::NodeCallback::operator()
{
osg::PositionAttitudeTransform* modelTransform; // local transform to
position the model in the world
osg::Node* someChild; // some model
osg::ref_ptr<osgFX::Effect> fxNode = new osgFX::Outline();
fxNode->addChild( someChild );
modelTransform->addChild( fxNode.get() );
}
Am I missing something obvious? If not, ideas or debugging strategies would
also be greatly appreciated!
Thank you!
Brian
