示例1:
void
ShaderGenerator::duplicateSharedNode(osg::Node& node)
{
if ( node.getNumParents() > 1 )
{
for(int i=1; i<(int)node.getNumParents(); ++i)
{
osg::Group* parent = node.getParent(i);
osg::Node* replicant = osg::clone(
&node,
osg::CopyOp::DEEP_COPY_NODES | osg::CopyOp::DEEP_COPY_DRAWABLES | osg::CopyOp::DEEP_COPY_ARRAYS);
parent->replaceChild(&node, replicant);
}
}
}示例2: vc
void
OcclusionQueryVisitor::addOQN( osg::Node& node )
{
VertexCounter vc( _occluderThreshold );
node.accept( vc );
if (vc.exceeded())
{
// Insert OQN(s) above this node.
unsigned int np = node.getNumParents();
while (np--)
{
osg::Group* parent = dynamic_cast<osg::Group*>( node.getParent( np ) );
if (parent != NULL)
{
osg::ref_ptr<osg::OcclusionQueryNode> oqn = new osg::OcclusionQueryNode();
oqn->addChild( &node );
parent->replaceChild( &node, oqn.get() );
oqn->setName( getNextOQNName() );
// Set all OQNs to use the same query StateSets (instead of multiple copies
// of the same StateSet) for efficiency.
oqn->setQueryStateSet( _state.get() );
oqn->setDebugStateSet( _debugState.get() );
}
}
}
