Constructor & Destructor Documentation

osgUtil::GLObjectsVisitor::GLObjectsVisitor ( Mode mode = COMPILE_DISPLAY_LISTS|COMPILE_STATE_ATTRIBUTES|CHECK_BLACK_LISTED_MODES )

Construct a GLObjectsVisitor to traverse all children, operating on node according to specified mode, such as to compile or release display list/texture objects etc.

Default mode is to compile GL objects.
