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

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

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

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

getContextID()

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

inline

References _contextID.

newFrame()

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

inlinevirtual

Signal that a new frame has started.

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

recomputeStats()

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

inlinevirtual

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

reportStats()

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

inlinevirtual

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

resetStats()

virtual void osg::GraphicsObjectManager::resetStats ( )

inlinevirtual

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