Member Function Documentation

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.

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.

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.
