GLObjectsVisitor()

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.
