Member Function Documentation

createGLObject()

virtual GLuint osg::GLObjectManager::createGLObject ( )

virtual

implementation of the actual creation of an GL object - subclasses from GLObjectManager must implement the appropriate GL calls.

deleteAllGLObjects()

virtual void osg::GLObjectManager::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.

deleteGLObject()

virtual void osg::GLObjectManager::deleteGLObject ( GLuint globj )

pure virtual

implementation of the actual deletion of an GL object - subclasses from GLObjectManager must implement the appropriate GL calls.

Implemented in osg::GLFrameBufferObjectManager, and osg::GLRenderBufferManager.

discardAllGLObjects()

virtual void osg::GLObjectManager::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::GLObjectManager::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::GLObjectManager::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.

scheduleGLObjectForDeletion()

virtual void osg::GLObjectManager::scheduleGLObjectForDeletion ( GLuint globj )

virtual

schedule a GL object for deletion by the graphics thread.
