[osg-submissions] osg::Object::clone

[Jean-Sébastien Guay]

Hello Michael,

> assert(b);

Will it? Just playing Devil's advocate here, I don't care either way, 
and I may be showing my poor C++ skills, but since the clone() method is 
virtual, a->clone() will return a Transform* (with Valery's changes), 
and dynamic_casting a Transform* to a Transform* will just be a no-op 
and return the same object, so the assert will not fail...

Or am I seeing this wrong?
