Member Function Documentation

◆ createNewContextID()

static unsigned int osg::ContextData::createNewContextID ( )

static

Create a contextID for a new graphics context, this contextID is used to set up the osg::State associate with context.

Automatically increments the usage count of the contextID to 1.

◆ decrementContextIDUsageCount()

static void osg::ContextData::decrementContextIDUsageCount ( unsigned int contextID )

static

Decrement the usage count associate with a contextID.

Once the contextID goes to 0 the contextID is then free to be reused.

◆ decrementUsageCount()

void osg::ContextData::decrementUsageCount ( )

inline

◆ deleteAllGLObjects()

virtual void osg::ContextData::deleteAllGLObjects ( )

virtual

Do a GL delete all OpenGL objects.

Note, must be called from a thread which has current the graphics context associated with contextID.

Implements osg::GraphicsObjectManager.

◆ discardAllGLObjects()

virtual void osg::ContextData::discardAllGLObjects ( )

virtual

Discard all OpenGL objects.

Note, unlike deleteAllGLjects discard does not do any OpenGL calls so can be called from any thread, but as a consequence it also doesn't remove the associated OpenGL resource so discard should only be called when the associated graphics context is being/has been closed.

Implements osg::GraphicsObjectManager.

◆ flushAllDeletedGLObjects()

virtual void osg::ContextData::flushAllDeletedGLObjects ( )

virtual

Flush all deleted OpenGL objects.

Note, must be called from a thread which has current the graphics context associated with contextID.

Implements osg::GraphicsObjectManager.

◆ flushDeletedGLObjects()

virtual void osg::ContextData::flushDeletedGLObjects	(	double	currentTime,
		double &	availableTime
	)

virtual

Flush all deleted OpenGL objects within the specified availableTime.

Note, must be called from a thread which has current the graphics context associated with contextID.

Implements osg::GraphicsObjectManager.

◆ get() [1/2]

template<typename T >

T* osg::ContextData::get ( )

inline

Get a specific GL extensions object or GraphicsObjectManager, initialize if not already present.

Note, must only be called from a the graphics context thread associated with this osg::State.

References osg::ref_ptr< T >::get().

Referenced by osg::get().

◆ get() [2/2]

template<typename T >

const T* osg::ContextData::get ( ) const

inline

Get a specific GL extensions object or GraphicsObjectManager if it already exists in the extension map.

Note, safe to call outwith a the graphics context thread associated with this osg::State. Returns NULL if the desired extension object has not been created yet.

◆ getAllRegisteredGraphicsContexts()

static GraphicsContexts osg::ContextData::getAllRegisteredGraphicsContexts ( )

static

Get all the registered graphics contexts.

◆ getCompileContext() [1/2]

osg::GraphicsContext* osg::ContextData::getCompileContext ( )

inline

◆ getCompileContext() [2/2]

static GraphicsContext* osg::ContextData::getCompileContext ( unsigned int contextID )

static

Get the GraphicsContext for doing background compilation for GraphicsContexts associated with specified contextID.

◆ getMaxContextID()

static unsigned int osg::ContextData::getMaxContextID ( )

static

Get the current max ContextID.

◆ getNumContexts()

unsigned int osg::ContextData::getNumContexts ( ) const

inline

◆ getOrCreateCompileContext()

static GraphicsContext* osg::ContextData::getOrCreateCompileContext ( unsigned int contextID )

static

Get existing or create a new GraphicsContext to do background compilation for GraphicsContexts associated with specified contextID.

◆ getRegisteredGraphicsContexts()

static GraphicsContexts osg::ContextData::getRegisteredGraphicsContexts ( unsigned int contextID )

static

Get all the registered graphics contexts associated with a specific contextID.

◆ incrementContextIDUsageCount()

static void osg::ContextData::incrementContextIDUsageCount ( unsigned int contextID )

static

Increment the usage count associate with a contextID.

The usage count specifies how many graphics contexts a specific contextID is shared between.

◆ incrementUsageCount()

void osg::ContextData::incrementUsageCount ( )

inline

◆ newFrame()

virtual void osg::ContextData::newFrame ( osg::FrameStamp * )

virtual

Signal that a new frame has started.

Reimplemented from osg::GraphicsObjectManager.

◆ recomputeStats()

virtual void osg::ContextData::recomputeStats ( std::ostream & out ) const

virtual

Reimplemented from osg::GraphicsObjectManager.

◆ registerGraphicsContext()

static void osg::ContextData::registerGraphicsContext ( GraphicsContext * gc )

static

Register a GraphicsContext.

◆ reportStats()

virtual void osg::ContextData::reportStats ( std::ostream & out )

virtual

Reimplemented from osg::GraphicsObjectManager.

◆ resetStats()

virtual void osg::ContextData::resetStats ( )

virtual

Reimplemented from osg::GraphicsObjectManager.

◆ set()

template<typename T >

void osg::ContextData::set ( T * ptr )

inline

Set a specific GL extensions object pr GraphicsObjectManager.

References osg::deleteAllGLObjects(), osg::discardAllGLObjects(), osg::flushAllDeletedGLObjects(), and osg::flushDeletedGLObjects().

◆ setCompileContext() [1/2]

void osg::ContextData::setCompileContext ( osg::GraphicsContext * gc )

	)

static

Get the GraphicsContext for doing background compilation for GraphicsContexts associated with specified contextID.

◆ setNumContexts()

void osg::ContextData::setNumContexts ( unsigned int numContexts )

inline

◆ unregisterGraphicsContext()

static void osg::ContextData::unregisterGraphicsContext ( GraphicsContext * gc )

static

Unregister a GraphicsContext.
