Thanks Robert for the reply.
I suspected a thread issus but since osgFX::Scribe code does not do anything
special regarding thread safety I expected my code should work fine as well.
Can you see the point in my code? Or maybe a threading issue in OSG code? The
difference wrt the osgFX::Scribe usage is that the Scribe node is removed from
the OSG graph in that case instead of removing attributes from stateset.
Code:
osg::ref_ptr< osg::Group > decorator; // class member
Constructor(osg::ref_ptr<osg::Node> iNode)
{
decorator = new osg::Group;
decorator->addChild(iNode);
iNode->getParent(0)->addChild(decorator);
osg::StateSet* stateset = decorator->getOrCreateStateSet();
osg::Material* material = new osg::Material;
stateset->setMode(GL_LIGHTING, osg::StateAttribute::OVERRIDE |
osg::StateAttribute::OFF);
stateset->setAttributeAndModes(material, osg::StateAttribute::OVERRIDE |
osg::StateAttribute::ON);
}
void removeWireframe()
{
osg::StateSet* stateset = decorator->getStateSet();
stateset->removeAttribute(osg::StateAttribute::POLYGONMODE);
stateset->removeAttribute(osg::StateAttribute::POLYGONOFFSET);
}
void setWireframe()
{
osg::StateSet* stateset = decorator->getStateSet();
osg::PolygonOffset* polyoffset = new osg::PolygonOffset;
polyoffset->setFactor(-1.0f);
polyoffset->setUnits(-1.0f);
stateset->setAttributeAndModes(polyoffset, osg::StateAttribute::OVERRIDE |
osg::StateAttribute::ON);
osg::PolygonMode* polymode = new osg::PolygonMode;
polymode->setMode(osg::PolygonMode::FRONT_AND_BACK, osg::PolygonMode::LINE);
stateset->setAttributeAndModes(polymode, osg::StateAttribute::OVERRIDE |
osg::StateAttribute::ON);
}
