Hi,
Perhaps I wasn't clear in my question so I will try once more, is there
a way to disable small feature culling for just a subgraph not the
entire scene?
Regards,

Hi,
I'm trying to disable small feature culling for a subgraph, but so far
I have not been able to disable it with other than calling
setCullingActive(false) on the leaf geodes. The leaf geodes are
actually shared between several subgraphs and I don't want to disable
small feature culling for all of them, so I need a way to disable
small feature culling higher up in the scenegraph.
I have tried to use a cull callback to disable small feature culling
for the subgraph but without success, the code for the cull callback
is pasted below.
class MyCullingCallback : public osg::NodeCallback
{
public:
MyCullingCallback() : osg::NodeCallback()
{}
virtual void operator() (osg::Node *node, osg::NodeVisitor *nv)
{
osgUtil::CullVisitor *cv = dynamic_cast<osgUtil::CullVisitor*>(nv);
if(cv){
osg::CullSettings::CullingMode cm = cv->getCullingMode();
cv->setCullingMode(cm & ~osg::CullSettings::SMALL_FEATURE_CULLING);
traverse(node,nv);
cv->setCullingMode(cm);
}else
traverse(node,nv);
}
};
...
node->setCullCallback(new MyCullingCallback);
Regards,
Per
