示例1: checkForRedundancy
void InventorLoader::checkForRedundancy( osg::NodePtr OSGGroup )
{
return;
// TODO: Check the type of the node and return, if it's not a node
// that should be discarded (discardable: group, not discardable: geometry)
// If the group node has no children, then let's kick it !
if( OSGGroup->getNChildren() == 0 )
{
if(OSGGroup->getParent() != NullFC)
{
OSGGroup->getParent()->subChild(OSGGroup);
}
else
{
subRefCP(OSGGroup);
}
}
// If there's only one child, then add it to the parent of the group,
// copy the name and remove the group
else if ( OSGGroup->getNChildren() == 1 )
{
// Get parent and child
osg::NodePtr _Child = OSGGroup->getChild(0);
osg::NodePtr _Parent = OSGGroup->getParent();
// Copy the name
const char* _Name = getName(OSGGroup);
if( _Name )
setName( _Child, _Name );
// Add the child to the parent
_Parent->addChild( _Child );
// Remove the group node
_Parent->subChild( OSGGroup );
