Public Member Functions

virtual const char * className () const
 
virtual void init (ViewDependentShadowTechnique *st, osgUtil::CullVisitor *cv)
 Method called upon ViewData instance to initialize internal variables.
 
virtual void cull ()
 Method called by ViewDependentShadowTechnique to allow ViewData do the hard work computing shadows for its associated view.
 
virtual void dirty (bool flag)
 Dirty is called by parent ViewDependentShadowTechnique to force update of resources after some of them were modified in parent technique.
 
 ViewData ()
 Simple constructor zeroing all variables.

virtual void setThreadSafeRefUnref (bool threadSafe)
 Set whether to use a mutex to ensure ref() and unref() are thread safe. More...
 
bool getThreadSafeRefUnref () const
 Get whether a mutex is used to ensure ref() and unref() are thread safe. More...

OpenThreads::MutexgetRefMutex () const
 Get the mutex used to ensure thread safety of ref()/unref(). More...
 
OpenThreads::MutexgetRefMutex () const
 
int ref () const
 Increment the reference count by one, indicating that this object has another pointer which is referencing it. More...
 
int unref () const
 Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it. More...
 
int unref_nodelete () const
 Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it. More...
 
int referenceCount () const

ObserverSetgetObserverSet () const
 Get the ObserverSet if one is attached, otherwise return NULL. More...
 
ObserverSetgetOrCreateObserverSet () const
 Get the ObserverSet if one is attached, otherwise create an ObserverSet, attach it, then return this newly created ObserverSet. More...
 
void addObserver (Observer *observer) const
 Add a Observer that is observing this object, notify the Observer when this object gets deleted. More...
 
void removeObserver (Observer *observer) const
 Remove Observer that is observing this object. More...
 

Public Attributes

OpenThreads::Mutex _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.
 
bool _dirty
 Dirty flag tells this instance to update its resources.
 
osg::observer_ptr< osgUtil::CullVisitor_cv
 View's CullVisitor associated with this ViewData instance.
 
osg::observer_ptr< ViewDependentShadowTechnique_st
 Parent ViewDependentShadowTechnique.

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.
