Member Function Documentation

◆ deleteAllGLObjects()

virtual void osg::GraphicsObjectManager::deleteAllGLObjects ( )
pure virtual

Do a GL delete all OpenGL objects.

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

Implemented in osg::TextureObjectManager, osg::GLBufferObjectManager, osg::GLObjectManager, and osg::ContextData.

◆ discardAllGLObjects()

virtual void osg::GraphicsObjectManager::discardAllGLObjects ( )
pure 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.

Implemented in osg::TextureObjectManager, osg::GLBufferObjectManager, osg::GLObjectManager, and osg::ContextData.

◆ flushAllDeletedGLObjects()

virtual void osg::GraphicsObjectManager::flushAllDeletedGLObjects ( )
pure virtual

Flush all deleted OpenGL objects.

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

Implemented in osg::TextureObjectManager, osg::GLBufferObjectManager, osg::GLObjectManager, and osg::ContextData.

◆ flushDeletedGLObjects()

virtual void osg::GraphicsObjectManager::flushDeletedGLObjects ( double  currentTime,
double &  availableTime 
)
pure 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.

Implemented in osg::TextureObjectManager, osg::GLBufferObjectManager, osg::GLObjectManager, and osg::ContextData.

◆ getContextID()

unsigned int osg::GraphicsObjectManager::getContextID ( ) const
inline

◆ newFrame()

virtual void osg::GraphicsObjectManager::newFrame ( osg::FrameStamp )
inlinevirtual

Signal that a new frame has started.

Reimplemented in osg::TextureObjectManager, osg::GLBufferObjectManager, and osg::ContextData.

◆ recomputeStats()

virtual void osg::GraphicsObjectManager::recomputeStats ( std::ostream &  ) const
inlinevirtual

◆ reportStats()

virtual void osg::GraphicsObjectManager::reportStats ( std::ostream &  )
inlinevirtual

◆ resetStats()

virtual void osg::GraphicsObjectManager::resetStats ( )
