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.


Member Function Documentation

virtual void osgUtil::GLObjectsVisitor::apply ( osg::Node node) [virtual]

Simply traverse using standard NodeVisitor traverse method.

Reimplemented from osg::NodeVisitor.

void osgUtil::GLObjectsVisitor::apply ( osg::StateSet stateset)
virtual void osgUtil::GLObjectsVisitor::apply ( osg::Geode node) [virtual]

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

Reimplemented from osg::NodeVisitor.

void osgUtil::GLObjectsVisitor::apply ( osg::Drawable drawable)
Mode osgUtil::GLObjectsVisitor::getMode ( ) const [inline]

Get the operational mode.
