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

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.

Mode osgUtil::GLObjectsVisitor::getMode

(

)

const [inline]

Get the operational mode.

void osgUtil::GLObjectsVisitor::setState

(

osg::State *

state

)

[inline]

Set the State to use during traversal.

osg::State* osgUtil::GLObjectsVisitor::getState

(

)

[inline]

void osgUtil::GLObjectsVisitor::setRenderInfo

(

osg::RenderInfo &

renderInfo

)

[inline]

osg::RenderInfo& osgUtil::GLObjectsVisitor::getRenderInfo

(

)

[inline]

virtual void osgUtil::GLObjectsVisitor::apply

(

osg::Node &

node

)

[virtual]

Simply traverse using standard NodeVisitor traverse method.

Reimplemented from osg::NodeVisitor.

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

)

void osgUtil::GLObjectsVisitor::apply

(

osg::StateSet &

stateset

)
