void osg::TextureObjectManager::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.

void osg::TextureObjectManager::discardAllDeletedGLObjects

(

)

void osg::TextureObjectManager::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.

void osg::TextureObjectManager::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.

void osg::TextureObjectManager::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.
