Hi, Thank you so much for your answers and you helped me a lot. But I don't know how to mark this question as "solved" because I am newbie here.
I raised this question because in the beginning I thought the osg::Vec3f is constructed using std::vector template (it seems that I was wrong:( ). So I was wondering why it cannot return NULL as vector did. Next I think I need to read the source code of osg to better understand the underlying stuff. Thank you!
