Given a nodepath, what is the correct way to extract the effective material
that will be used to render the node? i.e. to take into account the attribute
inheritance and overrides etc.
My first stab looked like the code below, which seemed to work for simple
cases, but not when the graph contained overrides etc.
Cheers
Chris.
Code:
osg::ref_ptr<osg::StateSet> stateSet = new osg::StateSet();
osg::NodePath::const_iterator& i = getNodePath().begin();
for (; i != getNodePath().end(); i++)
{
osg::Node* node = *i;
const osg::StateSet* merge = node->getStateSet();
if (merge) stateSet->merge(*merge);
}
const osg::Material* material = NULL;
material = dynamic_cast<const
osg::Material*>(stateSet->getAttribute(osg::StateAttribute::MATERIAL));
