Detailed Description

Base container class for view dependent shadow resources. Techniques based on ViewDependentShadowTechnique will usually define similar struct and derive it from ViewData to contain their specufic resources.

Constructor & Destructor Documentation

osgShadow::ViewDependentShadowTechnique::ViewData::ViewData ( void  )

inline

Simple constructor zeroing all variables.

Member Function Documentation

virtual const char* osgShadow::ViewDependentShadowTechnique::ViewData::className ( ) const

inlinevirtual

virtual void osgShadow::ViewDependentShadowTechnique::ViewData::cull ( )

virtual

Method called by ViewDependentShadowTechnique to allow ViewData do the hard work computing shadows for its associated view

Reimplemented in osgShadow::StandardShadowMap::ViewData, and osgShadow::DebugShadowMap::ViewData.

virtual void osgShadow::ViewDependentShadowTechnique::ViewData::dirty ( bool  flag )

virtual

Dirty is called by parent ViewDependentShadowTechnique to force update of resources after some of them were modified in parent technique

virtual void osgShadow::ViewDependentShadowTechnique::ViewData::init ( ViewDependentShadowTechnique *  st, osgUtil::CullVisitor *  cv  )

virtual

Method called upon ViewData instance to initialize internal variables

Member Data Documentation

osg::observer_ptr< osgUtil::CullVisitor > osgShadow::ViewDependentShadowTechnique::ViewData::_cv

View's CullVisitor associated with this ViewData instance

bool osgShadow::ViewDependentShadowTechnique::ViewData::_dirty

Dirty flag tells this instance to update its resources

OpenThreads::Mutex osgShadow::ViewDependentShadowTechnique::ViewData::_mutex

Mutex used to guard _dirty flag from override in case when parent technique calls dirty() simultaneously with ViewData while it is updating resources inside init method.

osg::observer_ptr< ViewDependentShadowTechnique > osgShadow::ViewDependentShadowTechnique::ViewData::_st

Parent ViewDependentShadowTechnique
