Detailed Description

Visitor for traversing scene graph and setting each osg::Drawable's _useDisplayList flag, with option to immediately compile osg::Drawable OpenGL Display lists and osg::StateAttribute's.

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.

Member Function Documentation

void osgUtil::GLObjectsVisitor::apply ( osg::StateSet & stateset )

void osgUtil::GLObjectsVisitor::apply ( osg::Drawable & drawable )

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.

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

Simply traverse using standard NodeVisitor traverse method.

Reimplemented from osg::NodeVisitor.

Mode osgUtil::GLObjectsVisitor::getMode ( ) const [inline]

Get the operational mode.

osg::State* osgUtil::GLObjectsVisitor::getState ( ) [inline]

virtual void osgUtil::GLObjectsVisitor::reset ( ) [inline, virtual]

Method to call to reset visitor. Useful if your visitor accumulates state during a traversal, and you plan to reuse the visitor. To flush that state for the next traversal: call reset() prior to each traversal.

Reimplemented from osg::NodeVisitor.

void osgUtil::GLObjectsVisitor::setMode ( Mode mode ) [inline]

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

void osgUtil::GLObjectsVisitor::setState ( osg::State * state ) [inline]

Set the State to use during traversal.
