Public Methods

GLObjectsVisitor(Mode mode=COMPILE_DISPLAY_LISTS|COMPILE_STATE_ATTRIBUTES)

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

void setMode(Mode mode)

Set the operational mode of what operations to do on the scene graph

Mode getMode() const

Get the operational mode

void setState(osg::State* state)

Set the State to use during traversal.

osg::State* getState()

virtual void apply(osg::Node& node)

Simply traverse using standard NodeVisitor traverse method

virtual void apply(osg::Geode& node)

For each Geode visited set the display list usage according to the _displayListMode
