Often you want to make a copy of a subtree, without actually duplicating all the data (e.g. to put it under a different transform). Given that OpenSG doesn't support multiple parents, you need to make a shallow copy, which contains separate Nodes, but shares all the NodeCores.

The helper function cloneTree takes care of that.

#!cpp

#include <OpenSG/OSGNode.h>



NodePtr copy = OSG::cloneTree(old_node);
